Grindelia squarrosa is probably native to the Great Plains and, perhaps, Rocky Mountain areas; it is widely introduced in other areas. Some plants are intermediate between it and G. hirsutula (i.e., between G. squarrosa and G. perennis, which has been treated as a variety of G. squarrosa). Plants of G. squarrosa with relatively narrow leaf blades (lengths mostly 5–8 times widths), mostly from the western part of the range of the species, have been treated as G. squarrosa var. serrulata. G. L. Nesom (1990i) and others have treated discoid plants included here in G. squarrosa as distinct (as G. aphanactis, G. nuda, and/or G. nuda vars. aphanactis and nuda); Nesom reported cypselae to be dimorphic in heads of radiate plants and monomorphic in discoid plants and noted that populations with discoid plants occur mostly south and west of populations with radiate plants. According to Nesom, plants of G. nuda with stems usually reddish (versus sometimes greenish), lengths of blades of mid-cauline leaves 4–10 (versus 1.5–4) times widths, and cypselae ± deeply furrowed (versus striate to shallowly furrowed) should be called G. nuda var. aphanactis.

Hybrids between Grindelia squarrosa (nuda) and G. arizonica have been recorded from Arizona and New Mexico.

Habitat characteristics ( Inglês )

fornecido por Fire Effects Information System Plants
Curlycup gumweed favors dry areas, but grows on moist soils that lack
other vegetation [17].  It is most common in dry prairies, waste places,
roadsides, railroads, depleted rangelands, and abandoned croplands.  It
often forms almost pure stands [14,15,31].

Curlycup gumweed growth is poor to fair on gravel, clay, and dense clay,
and good in sandy loam, loam, and clayey loam.  It makes fair growth on
saline soils, good growth on gentle and moderate slopes, and fair growth
on steep slopes.  Optimum soil depth is 10 to 20 inches (25-50 cm) [8].

In eastern North Dakota, curlycup gumweed occurred on saltflats and in
wet lowlands where salinity ranged up to 1.3 percent [28].

Curlycup gumweed occurs at the following elevations [8,15,29]:

                   Elevation (feet)    Elevation (m)

          CO         3,500-8,500        1,067-2,590

More info for the term: cover

Curlycup gumweed increases with grazing [18] and has a negative economic
impact on rangelands [8].  It forms dense, brushlike cover in rangelands
where there is much broken sod [35].  In the Central Great Plains, it is
not usually found on ranges of excellent or good condition, but is found
on ranges in fair condition [20].

Curlycup gumweed stems, leaves, and flowers produce a sticky exudate.
The coats of livestock can become gummed with it [2].

Curlycup gumweed is drought resistant due to deep roots and resinous
secretions [1].

Curlycup gumweed is a facultative selenium absorber [1].

Native Americans used curlycup gumweed extracts to treat asthma,
bronchitis, colic, and skin rash [17].  The Pawnees boiled the flower
heads and leaves, and used the decoction for bathing saddle sores and
other skin irritations [1].  Today, medicinal uses include treatment of
bronchial spasm, whooping cough, asthma, and rashes caused by poison ivy
(Toxicodendron radicans) [17].  Curlycup gumweed extract is valuable as
a stimulant, sedative, astringent, purgative, emetic, diuretic,

Curlycup gumweed forms a rosette the first year.  The next summer, the
plant grows erect stems which branch considerably and produce many
flower heads [12,35].

Curlycup gumweed flowering times are [1,10,14,22,23,31]:

                    Begin         Peak           End
                  Flowering     Flowering     Flowering

     CA             July          ----        September

     WY             July         August       September
     Great Plains   July          ----          ----
     New England    July          ----        September

In North Dakota, curlycup gumweed began growth in May, and by the end of
May had attained 50 percent of its yearly growth [13].  Curlycup gumweed
attained maximum height in August.  The average length of flowering
period was 41 days; the median date when flowering was 95 percent
complete was September 4 [4].

Plant Response to Fire ( Inglês )

fornecido por Fire Effects Information System Plants
More info for the terms: cover, natural, wildfire

Curlycup gumweed colonizes disturbed areas, and establishes or increases
after fire.

Curlycup gumweed was a trace species with 0.1 percent cover before a
natural range fire occurred in a cheatgrass (Bromus tectorum)-sand
dropseed (Sporobolus cryptandrus)-red threeawn (Aristida longiseta)
community during the summer of 1956.  It was not present the first
growing season following the fire, in 1957.  At the end of the next
growing season, its cover was 1.2 percent.  During the next
2 years it was present only in trace amounts [5].

Curlycup gumweed populations increased following a 1983 or 1984 wildfire
of unknown intensity and season in a 9,600 square foot (800 sq m) area
in central Utah [21].

Successional Status ( Inglês )

More info for the terms: association, climax, forbs, succession

Curlycup gumweed is subdominant in climax prairie communities [6].  It
also occurs on disturbed sites [14].  It is highly drought resistant,
and may be abundant after dry periods [17].  However, by 1943 curlycup
gumweed in the mixed-grass prairie of Kansas showed only partial
recovery from the great drought of the 1930s [7].

In a black-tailed prairie dog town in a tallgrass prairie in
southwestern Oklahoma, prairie dogs of one colony progressively
retreated from the outside of the colony toward its center prior to
abandoning it.  Plant succession at this site was studied the summer
after the animals left.  Order of succession was apparent in concentric
rings of vegetation circumscribing a bare area at the center of the
colony.  Curlycup gumweed did not occur in the most recently abandoned
area, the colony center.  It did occur in longer-abandoned, surrounding
rings in association with annual threeawn (Aristida oligantha) and other
short grasses, forbs, and mid-sized grasses such as sideoats grama.  It
was not found in the undisturbed peripheral rings, which supported
climax tall grasses such as big bluestem [25].

Curlycup gumweed occurred in only trace amounts on unreclaimed and
reclaimed bentonite mine spoils in southeastern Montana.  It occurred in
greater abundance on adjacent grasslands [30].

Curlycup gumweed was used in a roadside reseeding project in southern
Wisconsin.  It showed a high ability to survive and grow under adverse
conditions.  Seedlings transplanted easily to the field and grew
rapidly.  Results for both direct seeding and seedling transplant were
excellent [24].

Úbor bez ligul Grindelia squarrosa nuda

Grindélie rozkladitá (Grindelia squarrosa) je okrasná dvouletá rostlina vysoká až 1 m, která v letních měsících květe žlutými květy sestavenými až do 20 úborů. Pochází ze Severní Ameriky, kde roste od jihu Kanady přes většinu území Spojených států až po střední Mexiko. Je pravděpodobné, že před rozsáhlým severoamerickým rozšířením se vyvinula na území Velkých planin a oblastí Skalnatých hor, kde se dosud vyskytuje do nadmořské výšky 2500 m n. m.

Tato nenáročná, hezky kvetoucí rostlina byla dovezena do Evropy a začala být pěstována v okrasných zahradách. Později byla rozšířena na Kavkaz, do Číny i na ruský Dálný východ, došlo k tomu pravděpodobně lidským přičiněním. Je bylinou s malých invazním potencionálem. Přestože je pěstována v okrasných zahradách, nejsou v České republice dosud důkazy pro to, že zplaňuje a uniká z kultivace do volné přírody.[1][2][3]

Ekologie

Je vhodnou květinou pro lehkou písčitou a středně těžkou, hlinitou půdu, která obsahuje jen málo živin. Půda může být kyselá, neutrální i zásaditá, důležitou podmínkou je však její dobré odvodnění, upřednostňuje spíše sucho než mokro. Na místech s výživnou a průběžně mírně vlhkou půdou vyrůstá rostlina do větší výšky a bývá rozložitější. Potřebuje dostatek slunce, ale na klima a nadmořskou výšku není příliš náročná. Období sucha dokáže dospělá rostlina přežít snížením emise vodní páry z listů.

Ve své domovině se obvykle vyskytuje na horských pastvinách, prériích, horských svazích, opuštěných polích, podél silnic, železničních tratí, na překladištích, skládkách a na jiných místech, kde byla v nedávné minulosti půda často narušována. Patří mezi prvé rostliny, které takovéto stanoviště osídlují, někdy se stává vážným plevelem pastvin. V prvém roce vyroste ze semene bazální růžice a druhým rokem se z kořenového systému vyvine jeden nebo více květonosných lodyh. Kvete od června do září. Ploidie druhu je 2n = 12.[1][2][4]

Popis

Dvouletá až krátce vytrvalá bylina s lodyhou vysokou 40 až 100 cm, vyrůstající z hrubého kořene s mnoha bočními vláknitými kořínky. Lodyha je pevná, vzpřímená, bohatě rozvětvená, lysá, zelená, nažloutlá nebo nafialovělá. Je porostlá střídavými, jednoduchými, přisedlými listy s čepelí podlouhlou, kopinatou nebo podlouhle vejčitou, dlouhou 3 až 5 cm, širokou 1 až 3 cm a lodyhu mírně objímající. Listy jsou poněkud zkroucené, na vrcholu zašpičatělé, po obvodě jemně zubaté s tupými žláznatými špičkami a na povrchu žláznatě tečkované, na dotek jsou mírně lepkavé a mají výraznou střední žilku. V horní části lodyhy jsou listy menší, více podlouhlé a někdy bývají po obvode hladké. Po poranění rostlina silně mlečí.

Na konci lodyhy a jejich větví vyrůstají samostatně nebo v chocholíku polokulovité úbory 2,5 až 3,5 cm velké s mnohořadým zákrovem, květenství mívá 3 až 20 úborů se sytě žlutými květy. Lůžko úboru je ploché nebo jen mírně vypouklé, uprostřed jsou oboupohlavné květy s pětičetnou korunou srostlou do trubky. Po obvodě je 24 až 36 jazykovitých, samčích květů s podlouhlou, jasně žlutou ligulou až 10 mm dlouhou a 3 mm širokou, která je zakončena třemi malými zuby. Zákrov úboru má silně lepkavé, namodralé, čárkovité, nazpět silně ohnuté nitkovité zákrovní listeny uspořádané v pěti či šesti řadách. Květy obsahují dostatek pylu i nektaru a jsou opylovány hlavně včelami i čmeláky.

V opylených květech vznikají plody, což jsou nažky 2 až 4 mm dlouhé, šedé až světle hnědé, podélně rýhované, s chmýrem 3 až 6 mm dlouhým.[1][2][4][5][6]

Rozmnožování

Rostliny se rozmnožují semeny (nažkami), která se vysévají na podzim, při jarním výsevu se pro dobré vzklíčení doporučuje tříměsíční stratifikace v chladu. Během prvého roku po vzejití semen se vytvoří jen nízká listová růžice s několika listy, která vytvoří hluboký kořínek. Během druhého roku z kořene vyroste jedna nebo více světle zelených, květných lodyh. Na stanovištích se rostliny většinou samy ze semen obnovují.[7]

Taxonomie

Grindélie rozkladitá se v Severní Americe vyskytuje ve třech poddruzích:

  • Grindelia squarrosa Pursh subs. squarrosa,
  • Grindelia squarrosa Pursh subs. nuda (Wood) A. Gray - úbory postrádají na vnějších květech liguly,
  • Grindelia squarrosa Pursh subs. serrulata (Rydb.) Steyerm. - má lodyhu porostlou větším počtem úzkých listů,

Nominátní poddruh squarrosa roste v celém areálu, ostatní poddruhy se vyskytují pouze ostrůvkovitě.[4][5][6][8]

Význam

Rostlina v současnosti slouží hlavně jako okrasná bylina nenáročná na substrát i klimatické podmínky. Obsahuje saponiny, oleanolové a grindelové kyseliny, pryskyřice, silice (borneol), flavonoidy třísloviny a mnohé minerální látky. V Americe byla dříve používána v léčitelství, má zklidňující a protikřečové účinky, snižuje srdeční frekvenci a podporuje při léčbě uvolňování hlenů a jejich vykašlávání, ceněna je hlavně při léčbě bronchiálního astmatu. Z listů a kvetoucích stonků se připravuje roztok používaný v homeopatii. Z kvetoucích úborů a nezralých plodů se získává žluté a zelené barvivo, listy jsou vhodné též k léčbě kožních ekzémů a popálenin. Grindelia squarrosa je schopná extrahovat z půdy selen.[1][2][7][9]

Grindelia squarrosa ( Alemão )

fornecido por wikipedia DE

Grindelia squarrosa ist eine Pflanzenart aus der Gattung Grindelia in der Familie der Korbblütler (Asteraceae). Sie gedeiht in den Steppen der Great Plains. Sie ist vor allem wegen ihres Harzes bekannt, das von den amerikanischen Ureinwohnern als Heilmittel verwendet wurde und in der Homöopathie eingesetzt wird. Der Gattungsname ehrt den deutsch-baltischen Arzt, Apotheker und Botaniker David Hieronymus Grindel (1776–1836).[1]

Blütenkorb im Detail

Vegetative Merkmale

Grindelia squarrosa wächst als zweijährige bis ausdauernde, krautige Pflanze oder Halbstrauch. Sie blüht allerdings für gewöhnlich schon im ersten Jahr und ist kurzlebig. Sie erreicht Wuchshöhen von selten nur 10 bis meist 40 bis 100 Zentimetern. Die selbstständig aufrechte Sprossachse ist kahl und weißlich oder strohfarben, selten rötlich oder gräulich.[2]

Die wechselständig an den Sprossachsen verteilt angeordneten Laubblätter sind im unteren Bereich gestielt, weiter oben sitzend. Die Blattbasis ist mehr oder weniger stängelumfassend. Die Blattspreite ist bei einer Länge von selten 10 bis überwiegend 15 bis 70 Millimetern zwei- bis fünf-, selten bis zu zehnmal so lang wie breit. Die Form wird als oval, eiförmig, verkehrt-eiförmig oder länglichen bis spatelförmig, verkehrt-lanzettlich, lanzettlich oder linealisch beschrieben. Der Blattrand ist vorwiegend gekerbt bis gesägt, mit drei bis sechs oder mehr gerundeten bis stumpfen, harzigen Zähnen pro Zentimeter. Seltener ist er ganzrandig. Das obere Ende der Spreite ist stumpf oder spitz und beide Seiten sind kahl und stark drüsig punktiert.[2]

Generative Merkmale

Die Blütezeit reicht in Nordamerika von Juli bis September oder manchmal Oktober.[2] Die körbchenförmigen Blütenstände stehen selten einzeln, sondern meist in offenen oder gedrängten schirmtraubigen Gesamtblütenständen zusammen. Der Hüllkelch (Involucrum) ist bei einer Höhe von 6 bis 11 Millimetern sowie einem Durchmesser von 8 bis 20 Millimetern breit-krugförmig bis halbkugelig oder kugelförmig. Die in fünf oder sechs Reihen stehende Hüllblätter (Involucralblätter) sind zurückgebogen bis ausgebreitet oder angedrückt. Die Hüllblätter sind fadenförmig oder linealisch bis lanzettlich-linealisch oder lanzettlich-pfriemlich, mit pfriemlichem bis zylindrischem Querschnitt. Ihr oberes Ende ist nach außen oft mehr oder weniger umgebogen bis hakenartig oder eingerollt, seltener fast gerade. Die Hüllblätter sind moderat bis stark harzig.[2]

Ein Blütenkorb enthält 24 bis 36 (12 bis 40) Zungenblüten, zuweilen fehlen Zungenblüten ganz, und viele Röhrenblüten. Die Zungen der Zungenblüten sind 8 bis 14 Millimeter lang.[2]

Früchte

Die weißlichen, strohfarbenen, braunen oder grauen Achänen sind 1,5 bis 4,5 Millimeter lang sind. Ihre oberen Enden sind glatt, kronenartig oder knaufartig. Ihre Seiten sind glatt, streifig oder ± gefurcht. Der Pappus besteht aus meist zwei oder drei, selten bis zu acht Schuppen oder Grannen. Die glatten oder bärtigen, ahlenförmigen Schuppen können gerade, gewunden oder gekraust sein. Die Grannen sind borstenförmig. Der Pappus ist mit einer Länge von 2,5 bis 5,5 Millimetern kürzer als die Röhrenblüten.[2]

Chromosomenzahl

Die Chromosomengrundzahl beträgt x = 6; es liegt Diploidie mit einer Chromosomenzahl von 2n = 12 vor.[3][2]

Vorkommen

Ursprünglich war Grindelia squarrosa wohl in den Great Plains und an den Rocky Mountains verbreitet. Von dort aus hat sie sich stark ausgebreitet und ist in Nordamerika vom südlichen Kanada über die gesamten Vereinigten Staaten mit Ausnahme des Südostens bis in den nördlichen mexikanischen Bundesstaat Chihuahua weitverbreitet.[2]

Neophytische Vorkommen wurden auch aus der Ukraine und aus Mitteldeutschland[4][5] gemeldet.

Grindelia squarrosa gedeiht auf Ödland und an Wegrändern auf bevorzugt trockenen Böden, aber auch auf feuchterem Untergrund. Auf überweideten Arealen ist diese Art oft bestandsbildend.

Systematik

Die Erstveröffentlichung erfolgte 1813 unter dem Namen (Basionym) Donia squarrosa durch Frederick Traugott Pursh in Flora Americae Septentrionalis; or, ..., 2, Seite 559. Die Neukombination zu Grindelia squarrosa (Pursh) Dunal wurde 1819 durch Michel Félix Dunal in Mémoires du Muséum d’Histoire Naturelle, 5, Seite 50 veröffentlicht.[6] In der Flora of Northamerica 2010 gelten Grindelia aphanactis Rydberg, Grindelia nuda Alph.Wood, Grindelia nuda var. aphanactis (Rydberg) G.L.Nesom, Grindelia serrulata Rydberg, Grindelia squarrosa var. nuda (Alph.Wood) A.Gray, Grindelia squarrosa var. serrulata (Rydberg) Steyermark als Synonyme für Grindelia squarrosa (Pursh) Dunal.[2]

Von Grindelia squarrosa wurden Varietäten beschrieben, die allerdings von vielen Autoren[2] nicht anerkannt sind:

  • Grindelia squarrosa (Pursh) Dunal var. squarrosa
  • Grindelia squarrosa var. serrulata G.L.Nesom
  • Grindelia squarrosa var. nuda (Alph.Wood) A.Gray – Umstritten ist auch, ob es sich bei diesen Pflanzenexemplaren ganz ohne Zungenblüten um eine eigene Art Grindelia nuda Wood handelt.[2]

Grindelia squarrosa bildet natürliche Hybriden mit Grindelia arizonica in Arizona und New Mexico.[2]

Heute sind vier Arten, die gemeinsam als Kalifornische Grindelien bezeichnet werden und Stammpflanzen für die pharmazeutische Droge Grindelia herba bzw. Grindeliakraut sind:

Verwendung

Grindelia squarrosa wurde von vielen nordamerikanischen Ureinwohnern als Medizinpflanze verwendet. Die Blackfoot verwendeten Wurzelextrakte bei Leberbeschwerden. Die Cheyenne setzten das Blütenharz bei Hautkrankheiten ein. Andere Völker verwendeten Extrakte aus dem Harz der Pflanzen bei Erkältungen, Bauchschmerzen oder als Verhütungsmittel.[7]

Die Pflanze wird aufgrund ihres hohen Gehalts an Mono- und Di-Terpenen, die in einen Kerosin- oder Düsentreibstoff ähnlichen Treibstoff umgewandelt werden können, als potenzielle Quelle für Biokraftstoffe untersucht.[8] Die Anpassung der Pflanze an das trockene Klima macht sie attraktiv, da ihr Anbau in Wüstengebieten nicht mit traditionellen Nahrungspflanzen konkurrieren würde.

Grindelia nuda ( Inglês )

fornecido por wikipedia EN

Grindelia squarrosa, also known as a curly-top gumweed or curlycup gumweed, is a small North American biennial or short-lived perennial plant.[2]

Description

G. squarrosa is a decumbent to erect, much-branched perennial herb or subshrub growing up to 100 centimetres (39+12 inches) tall. The leaves are 1.5–7.5 cm (12–3 in) long,[3] gray-green, crenate with each tooth having a yellow bump near its tip, and resinous.[4][5]

The plant produces numerous flower heads in open, branching arrays. Each head usually contains 12–40 yellow ray flowers, though sometimes the rays are absent. These surround many small disc flowers. The plant blooms from July through late September.[4][6][5] The brown seed is usually four-angled, with loose scales.[3]

A form with rayless flowers is sometimes considered a distinct species.

Varieties

  • Grindelia squarrosa var. quasiperennis[7]
  • Grindelia squarrosa var. serrulata[8]
  • Grindelia squarrosa var. squarrosa[9]

Distribution and habitat

The species is native to western and central North America, from British Columbia east to Québec and New England, and south as far as California, New Mexico, Arizona, Chihuahua, and Texas. The species may possibly be naturalized in much of the eastern part of that distribution.[10][11][4][12]

It is often found in dry, open areas[3] and disturbed roadsides and streamsides, occurring between 700 metres (2,300 feet) and 2,300 metres (7,500 feet) in elevation.[4]

Ecology

The species is listed by the Lady Bird Johnson Wildflower Center Native Plant Information Network as of "Special Value to Native Bees."[12]

Toxicity

The plant concentrates selenium from the soil,[3] and can be toxic when ingested by cattle, humans, and other mammals.[4]

Uses

The flowers and leaves are used by Great Plains Tribes as a medicinal herb to treat illnesses such as asthma, bronchitis or skin rashes.[12][13][14] The powdered flowers were also once smoked in cigarettes to ease asthmatic symptoms.[15]

It is used as a traditional medicinal plant by Shoshone peoples in various regions.[13] The Gosiute language name for the plant is mu’-ha-kûm.[16] The Lakota language name for the plant is pteíčhiyuȟa.

Hispanos of New Mexico boiled the buds to make a drink to treat kidney disorders.[3] Extracts have been made to treat skin irritations, asthma, and rheumatism.[3] The resin has been used to treat poison ivy rashes topically.[17]

The plant is being explored as a potential source of biofuel due to its high content of mono- and di-terpenes which can be converted to a fuel analogous to kerosene or jet fuel.[18] The plant's adaptation to arid climates makes it an attractive option as its cultivation in desert areas would not compete with traditional food crops.

Гринделія розчепірена ( Ucraniano )

fornecido por wikipedia UK

Морфологічна характеристика

Стебло розгалужене, до 60 см заввишки. Листки довгасті, стеблообгортні, цілісні. Квітки жовті, в кошиках, що утворюють волоте- або щиткоподібне смолянисте суцвіття; крайові квітки — язичкові, неплідні; серединні — трубчасті, двостатеві. Цвіте у червнівересні. Плідсім'янка.

Поширення

Росте повсюди як бур'ян, найчастіше уздовж доріг на сухих місцях.

Спочатку цей вид був, ймовірно, поширений на Великих рівнинах і Скелястих горах. Звідти він поширювався і далі, розповсюдився по всій території Сполучених Штатів, за винятком південного сходу, на півдні Канади і на півночі Мексики. Пізніше, випадки поширення гринделії, було зареєстровано в Україні і Центральній Німеччині [1].[1]

Використання

Грінделія використовувалася багатьма племенами індіанців як лікарська рослина. Кореневі екстракти застосовували Blackfoot, під час скарг на печінку. Cheyenne, прикладали смоляні квіти, у разі шкірних захворювань. Екстракти смоли рослини, вживали за застуди, під час бронхіту або як контрацептиви. [2][2]

Для лікарських потреб заготовляють надземну частину рослини під час цвітіння.

Рослина містить глікозиди, борнеол, сапоніни, флавоноїди, фітостерол, фенол, селен.

Галенові препарати гринделії розчепіреної мають спазмолітичні, антисептичні, протиалергічні, відхаркувальні, сечогінні властивості. Застосовують при фарингіті, трахеїті, бронхіті, набряках, гіпотонії, алергії.

Внутрішньо — настій трави гринделії розчепіреної (20 г сухої трави заливають 200 мл окропу, настояти 50 хв) пити по 1 ст ложці 4 рази на день. Настоянку трави гринделії (10 г сухої трави на 50 мл 70 % розчину спирту, настоювати 5 днів) приймати по 40 крапель тричі на день. Зовнішньо — настоянку гринделії розчепіреної (1:5 на 70 % розчині спирту) для компресів та примочок перед застосуванням її розводять кип'яченою водою (1:3). Добрий ефект дає настоянка розведена на воді 1:2 при вуграх, гноячкових пошкодженнях шкіри обличчя.
