A. Cronquist (1969) placed Carex capitata in Utah; the species is not listed by B. J. Albee et al. (1988), nor have specimens been seen from there.

In Scandinavia (L. Reinhammar 1999) and Russia (T. V. Egorova 1999), Carex arctogena is distinguished from C. capitata on ecologic and morphologic grounds and also by allozymes at the rank of species. In North America the distinctions are not clear; two taxa can be observed, but there are also numerous specimens of uncertain determination. When making new collections, it is important to evaluate the differences seen elsewhere and to pay close attention to habitat and habit (see below). Separate status at some rank may be appropriate for the taxon “arctogena” in North America too. If C. antarctogena Roivainen from Tierra del Fuego is placed within C. capitata as D. M. Moore and A. O. Chater (1971) and D. M. Moore (1983) have done, then the species occurs at both the northern and the southern extremes of the Americas.

Carex capitata and C. arctogena differ in habitat (boreal mires versus alpine heaths), habit (mat-forming versus tufted), and morphology of the pistillate scales (much shorter and narrower than perigynia and with narrow hyaline margins versus as long as perigynia and with broad hyaline margins) and perigynia (beak gradually formed and smooth versus beak and may be sparingly serrulate).

Description ( Inglês )

fornecido por Fire Effects Information System Plants
More info for the terms: achene, caespitose, culm, graminoid, monoecious

Capitate sedge is a native, perennial, monoecious graminoid [8,10]. It
is loosely to densely caespitose [8,11]. Culms are 4 to 14 inches
(10-35 cm) tall [1,10]. Leaves are one to four per culm [8] and 0.02
inches (0.5 mm) wide or less [1,14,18]. The first foliage leaves arise
well above the base of the plant [10]. The inflorescence is a solitary
terminal spike [10] 0.16 to 0.39 inches (4-10 mm) long [8,14]. The
achene is 0.06 inches (1.5 mm) long [8]. The perigynia surrounding the
achene is ovate and 0.08 to 0.12 inches (2-3 mm) long [1,14]. There are
6 to 25 pergynia per spike [7,9]. Capitate sedge has short creeping
rhizomes [8] on which the culms are closely spaced [23].

Fire Ecology ( Inglês )

fornecido por Fire Effects Information System Plants
More info for the term: fire regime

Since capitate sedge can reproduce vegetatively [8,10], it probably
sprouts from rhizomes after aerial portions are burned. Where thick
tufts form, they may protect basal buds from fire-caused damage.

Habitat characteristics ( Inglês )

fornecido por Fire Effects Information System Plants
Capitate sedge is found in arctic and alpine environments [10] on marshy
meadows to dry alpine slopes [14,23]. It grows on acidic rocky,
gravelly [7], sandy [15], or peaty [5] soils.

In the alpine zone of the eastern Cascade Range in southern interior
British Columbia capitate sedge is dominant where the soil is strongly
acid (pH 4.9-5.3) and coarse textured, with loamy sand predominating
[15]. In the alpine zone of Mt. Baker, Washington, capitate sedge only
grew in the drier eastern region, on sites with the least snow
accumulation. However, the soils there remained moist well into summmer
because of drainage from upslope [3].

Capitate sedge is found at the following elevations:

Elevation (feet) Elevation (m)

AK 0- 3,281 0-1,000 [11]
CA 6,234-12,900 1,900-3,932 [9,14]

More info for the terms: fruit, seed

Capitate sedge blooms from July 1 to August 30 in New England [18] and
from late June to August in adjacent Canada [5].

Capitate sedge showed little phenological variation due to aspect in the
alpine zone of the eastern Cascade Range in southern interior British
Columbia. Snow had melted from the site by the third week of June in
1980. Capitate sedge broke dormancy the last week of June and grew
vegetatively until the first week of July. At that time it began to
flower, and continued to do so until the second week of August (except
at one site, where flowering ended August 3). It set fruit until the
first week of September, and dispersed seed after that time [16].

Carex capitata ( Checo )

fornecido por wikipedia CZ

Carex capitata L. je druh jednoděložné rostliny z čeledi šáchorovité (Cyperaceae).

Popis

Jedná se o vytrvalou trsnatou rostlinu, která dosahuje výšky 15-30 cm.[1] Listy jsou střídavé, přisedlé, s listovými pochvami. Čepele listu jsou žlábkovité a štětinovité.[1] Carex capitata patří mezi jednoklasé ostřice, to znamená, že na vrcholu lodyhy je pouze 1 klásek, který je hlávkovitý, asi 5–8 mm dlouhý. Je to rostlina jednodomá, v horní části klásku se nacházejí samčí květy, v dolní samičí. Okvětí chybí. V samčích květech jsou zpravidla 3 tyčinky. Blizny jsou většinou 2. Plodem je mošnička, která je asi 2–4 mm dlouhá a 1,5–1,8 mm široká, na vrcholu zakončená krátkým zobánkem.[2] Každá mošnička je podepřená plevou, která je kratší než mošnička a na okraji je úzce až široce lemovaná. Počet chromozómů: 2n=50.[2]

Rozšíření

Jedná se o severský a horský druh. Roste na Islandu, v Grónsku, ve Skandinávii, v severním Rusku, na Sibiři, na jihu jen izolovaně Kavkaz a Alpy. Dále roste v Severní Americe, hlavně Aljaška a Kanada. Další rozšíření je v Jižní Americe, Patagonie, Ohňová země.[3][2] Evropští autoři někdy odlišují blízce příbuzný druh Carex arctogena, jinými autory je uznáván jen jako poddruh Carex capitata. V Severní Americe se zdá, že jsou taxony méně vyhraněny.[2] Liší se i ekologicky, Carex capitata roste většinou na mokřinách, zatímco Carex arctogena na suchých vřesovištích.[2] Carex arctogena je známa hlavně ze Skandinávie, Grónska a Kanady, v Alpách neroste.[4] V ČR neroste ani jeden z druhů.

Kopf-Segge ( Alemão )

fornecido por wikipedia DE

Die Kopf-Segge (Carex capitata)[1][2] ist eine Pflanzenart aus der Gattung der Seggen (Carex) innerhalb der Familie der Sauergrasgewächse (Cyperaceae).[1] Sie ist auf der Nordhalbkugel in Eurasien und Nordamerika verbreitet.[3]

Beschreibung

 src=
Carex capitata im Botanischen Garten
 src=
Jeder Fruchtstand umfasst nur ein Ährchen

Die Kopf-Segge ist eine sommergrüne,[2] ausdauernde krautige Pflanze und erreicht Wuchshöhen von 15 bis 25 Zentimetern.[1] Sie besitzt kein Ausläufer und bildet kleine, feste Horste.[1] Die starr aufrecht Stängel sind dreikantig, und unter dem Blütenstand fühlbar rau.

Die Kopf-Segge ist eine einährige Segge. Das dichtblütige Ährchen ist kugelig mit einer Länge von bis zu 8 Millimetern.[1] Die Schläuche sind 2,3 bis 3 Millimeter lang und bis zu 2 Millimeter breit, sie laufen in einen kurzen Schnabel aus, der länger ist als die Spelzen.[1] Es sind zwei Narben vorhanden.[1]

Die Chromosomenzahl beträgt 2n = 50.[4]

Ökologie

Bei der Kopf-Segge handelt es sich um einen Hemikryptophyten.[1][2] Die Blütezeit reicht von Mai bis Juni.

Vorkommen

Carex capitata ist auf der Nordhalbkugel in Eurasien und Nordamerika verbreitet.[3] In Skandinavien kommt die Kopf-Segge noch bestandsbildend vor.[5] In Mitteleuropa muss die Kopf-Segge als Eiszeitrelikt angesehen werden.[5] Sie gedeiht in Gesellschaften der Ordnung Tofieldietalia.[4] In Mitteleuropa ist sie schon seit der Jahrhundertwende selten und nur von wenigen Fundorten des Alpenvorlands und aus Tirol bekannt.[5] Die Kopf-Segge wurde außerhalb der Alpen durch Trockenlegen von Mooren vermutlich vernichtet, und sie hat heute vermutlich in Mitteleuropa keinen Dauerwuchsort mehr.[5] In der Roten Liste der gefährdeten Pflanzenarten Deutschlands wurde die Kopf-Segge 1996 als ausgestorben oder verschollen bewertet.[1] Mit Sicherheit sind die Standorte im Bayerischen Alpenvorland und im Bodenseegebiet seit etwa 1950 nicht mehr bestätigt worden.[2] Eventuell gibt es noch Vorkommen bei Nauders im oberen Inntal.[5]

Die Kopf-Segge wächst auf nassen, mäßig sauren, aber nährstoffreichen Untergrund.[5] Sie besiedelt daher vor allem Zwischen- und Flachmoore, sie geht aber auch in Schlenken junger Hochmoore.[5]

Obwohl eine Neuansiedlung unwahrscheinlich ist, darf man sie doch nicht völlig ausschließen, denn ihre Früchte werden durch ziehende Wasservögel ausgebreitet.[5]

Die Zeigerwerte nach Ellenberg sind: Lichtzahl L9 = Volllichtpflanze; Temperaturzahl T4 = Mäßigwärme- bis Kühlezeiger; Kontinentalitätszahl K7 = subkontinental bis kontinental, gemäßigtes Steppen- bis Steppenklima zeigend; Feuchtezahl F8w = Feuchte- bis Nässezeiger; Feuchtewechsel = stark wechselnde Feuchte zeigend, Wechselfeuchtezeiger; Reaktionszahl R7 = Schwachsäure- bis Schwachbasenzeiger; Stickstoffzahl N1 = stickstoffärmste Standorte anzeigend; Salzzahl S0 = nicht salzertragend; Schwermetallresistenz = nicht schwermetallresistent.[1][2]

Lettonuppisara ( Finlandês )

fornecido por wikipedia FI

Lettonuppisara eli nuppisara (Carex capitata) on sarojen (Carex) sukuun kuuluva kasvilaji. Se kasvaa pienehköinä mättäinä ja sen varret ovat kasvutavaltaan selvästi pystyjä. Lettonuppisaran kukintona on yksi tähkä, joka sijaitsee varren päässä. Tähkän yläosassa on hedekukkia ja alaosassa emikukkia. Emikukat ovat kaksiluottisia. Pullakot ovat vihertäviä sekä leveitä, ja niissä on lyhyt sekä sileä suuota.[1]

Lettonuppisaran alalajina tai muunnoksena on aiemmin ja joskus myös nykyäänkin pidetty tunturinuppisaraa (Carex arctogena), mutta lajit ovat erotettavissa kukintotähkän koon sekä pullakoiden värityksen, muodon ja suuodan ulkonäön perusteella.[1]

Lettonuppisara on tunturinuppisaran tavoin harvinainen, joskin sitä selvästi yleisempi, ja kasvaa pohjoisessa kosteilla kalkkipitoisilla kasvupaikoilla.[1] Suomessa lettonuppisaraa tavataan eri puolilla Lapin maakuntaa, yleisimmin Enontekiöltä, mutta muutamia havaintoja on myös etelämpää, Kainuusta.[2]

Lettonuppisara on löydetty Ruotsissa Lapista ja löytö on julkaistu vuonna 1759.[1]

Huvudstarr (Carex capitata) är en flerårig gräslik växt inom släktet starrar och familjen halvgräs. Huvudstarr växter tätt tuvad och har rödbruna basala slidor, med strån ofta upprätta. De blekgörna smala bladen är kortare än ståna. De brungröna axen blir från sex till nio mm, är klotrunda och har några hanblommor i toppen. De gulbruna axfjällen blir cirka två mm, är äggrunda, trubbiga och har en hinnkantad spets. De blekgröna till gulbruna fruktgömmena blir från 3 till 3,5 mm, är släta och utan nerver, med en kort slät näbb. Huvudstarr blir från 10 till 40 cm hög och blommar från juni till juli.

Utbredning

Huvudstarr är ganska sällsynt i Norden, men kan återfinnas på fuktig, kalkrik torvmark, såsom kalkkärr, våtkärr, klippor, hedar, stränder och bäckkanter. Dess utbredning i Norden sträcker sig till ej kustnära områden i norra Finland, norra och mellersta Sverige, Nordnorge och så gott som hela Island.

Мешочки уплощённо плоско-выпуклые, яйцевидные, округло-яйцевидные или широко-эллиптические, (2,5)3,3—3,7(4) мм длиной, перепончатые, зелёные (или кверху буроватые), возможно лоснящиеся, зрелые слабо отклонённые от оси колоска, без жилок, сидячие, по краям гладкие или рассеянно-шероховатые, с коротким цельным или коротко-двузубчатым гладким носиком. Рылец 2.

Плод при основании с осевым придатком. Плодоносит в июле—августе.

Число хромосом 2n=50.

Вид описан из Европы.

Советскими и российскими ботаниками в отдельный вид Carex arctogena H.Smith, описанный из Швеции в 1940 г., выделяются растения отличающиеся более тёмными и мелкими колосками (4—6 мм длиной и 4—5 мм в диаметре, а не 6—10 мм длиной и (4)5—6 мм в диаметре), более длинными и широкими кроющими чешуями и более мелкими мешочками (2,5—3 мм длиной, а не (3)3,3—3,7(4) мм), кроме того у Carex arctogena H.Smith края мешочков гладкие, а не рассеянно-шероховатые, форма мешочков округло-яйцевидная или широко-эллиптическая, а не яйцевидная, а плод почти полностью заполняет мешочек, а не на 2/3. Также в отдельный вид Carex antarctogena Roivainen, возможно идентичный Carex arctogena H.Smith, выделяются растения, произрастающие на Огненной Земле.
