Comprehensive Description

provided by Smithsonian Contributions to Botany
Adiantum raddianum Presl

Adianthum raddianum Presl, Tent. Pterid. 158, 1836.—Tryon, Contr. Gray Herb. 144:169, 1964.—Hoshizaki, Baileya 17:134, 1970.

Adiantum cuneatum Langsdorff & Fischer, Ic. Fil. 23, t. 26, 1810.—Fosberg, Bull. Torr. Bot. Cl. 70:387, 1943; Occ. Pap. Bishop Mus. 24:11, 1969 [non A. cuneatum Forster, Prodr. 84, 1786].

According to Hoshizaki this is the plant commonly known in cultivation as A. cuneatum, and undoubtedly the plant widely escaped and naturalized in the Hawaiian Islands. Her illustration shows precisely the pinnule shape and the veins terminating in the sinuses between the lobes on sterile portions of the distal margins of the pinnules shown by the plant introduced in Hawaii. There are numerous horticultural varieties of this species, some of which are illustrated by Mrs. Hoshizaki.

Tryon was apparently the first to indicate that A. raddianum Presl is the earliest available name for this species, since A. cuneatum is antedated by A. cuneatum Forster. We may further point out that A. cuneatum Langsdorff & Fischer and A. raddianum Presl are nomenclaturally equivalent, as the latter is based on a supposed A. cuneatum Raddi (1825: [59, 100] pl. 78, 2a, b). Raddi was merely using Langsdorff’s and Fischer’s name, though ascribing it to Willdenow (1810:450). Willdenow merely included A. cuneatum Langsdorff & Fischer in his account of the genus. Raddi’s illustration, though not showing venation, seems clearly to apply to the plant described by Langsdorff and Fischer.

Adiantum raddianum

provided by wikipedia EN

Adiantum raddianum, the Delta maidenhair fern, is one of the most popular ferns to grow indoors.[3] It is native to South America and its common name comes from its shiny, dark leafstalks that resemble human hair.[4] It typically grows about 17–19 in (43–48 cm) tall and up to 22 in (56 cm) wide.[5] In the wild, it is found on forest floors, rock crevices, river banks, coastal cliffs, and basalt banks along trails and streams.[6] The triangular fronds are semi-erect in the beginning then droop gracefully as they age and can be up to 12 inches (30 cm)[7] long by 6 inches (15 cm) wide. The genus name Adiantum comes from the Greek word "adiantos", meaning "unwetted" (in reference to the leaves).[5]

This plant is hardy down to 5 °C (41 °F), so must be grown indoors in temperate regions. However it may be placed outside in a sheltered spot during the summer months.[8] It requires high humidity, well-drained soil, bright indirect light, and a fairly constant temperature.[3] It prefers neutral or slightly alkaline soil and is suitable for USDA hardiness zones 10 and 11.[9] It can be susceptible to scale and mealybug.[4] The cultivars ‘Brilliantelse’ and ‘Kensington Gem’ have won the Royal Horticultural Society's Award of Garden Merit.[8][10]

A. raddianum is sometimes considered invasive in Hawaii and French Polynesia.[6]

Adiantum raddianum ( Galician )

provided by wikipedia gl Galician

Adiantum raddianum tamén coñecida cos nomes vulgares de coantriño, cuadrillo ou cabelo de venus[1] é unha especie de fento de orixe americana pertencente á familia Pteridaceae. É un dos fentos máis populares para cultivo coma planta de interior[2][3] Aseméllase moito á especie europea capilaria (Adiantum capillus-veneris), coa que ás veces se confunde, a diferenza está na marxe das follas, na capilaria son máis dentadas.

As frondes son triangulares, semierectas no inicio, curvándose á medida que envellecen, podendo atinxir 8 cm de longo e 6 cm de largura[4].

Hábitat

Paredes de rocha sombrías e húmidas, fendas, cantís e cavorcos ao longo de ríos e fervenzas.

Distribución

Orixinaria de América do Sur tropical, espallouse polos seres humanos grazas ao seu valor decorativo a outras zonas como Hawai, África tropical e incluso á Europa atlántica (Holanda, Azores, Madeira, Galicia...)

Taxonomía

A especie foi descrita por Carl Bořivoj Presl e publicada en Tentamen Pteridographiae 158. 1836., no ano de 1836.[5]

Non se encontra protexida pola lexislación europea.

Fijn venushaar ( Dutch; Flemish )

provided by wikipedia NL

Het fijn venushaar (Adiantum raddianum) is een varen uit de lintvarenfamilie (Pteridaceae). De plant is oorspronkelijk uit Zuid-Amerika afkomstig, maar is ondertussen over andere tropische streken verspreid. De varen wordt in Nederland verwilderd aangetroffen.

Naamgeving en etymologie

  • Engels: Delta maidenhair

De botanische naam Adiantum is afgeleid van het Oudgriekse ἀδίαντος, adiantos (niet-bevochtigd), vanwege de waterafstotende blaadjes. De soortasanduiding raddianum is een eerbetoon aan Giuseppe Raddi (1770–1829), een Italiaanse botanicus uit Florence.

Kenmerken

Het fijn venushaar is een overblijvende, hemikryptofiete varen met korte, kruipende, vertakte en geschubde rizomen waaruit tot 60 cm lange bladen ontspringen. De stevige bladstelen zijn iets langer dan de bladschijf, aan de basis eveneens geschubd, donker van kleur.

 src=
Fijn venushaar, met sporenhoopjes onder de omgekrulde bladtoppen.

De bladschijf is ovaal tot breed ovaal van vorm, tot driemaal geveerd. De individuele bladslipjes zijn gesteeld, symmetrisch, smal of breed wigvormig, tot 1 cm lang, dun, ondiep gelobd of onregelmatig ingesneden, de lobben fijn getand. De nerven eindigen tussen de tandjes op de bladrand.

De sporenhoopjes zijn rond of niervormig en liggen aan de toppen van de onderzijde van de bladen, onder de omgerolde bladranden. Er is geen dekvliesje.

Habitat

Het fijn venushaar is een terrestrische of lithofytische plant die, net als het echt venushaar, vooral voorkomt op vochtige en halfbeschaduwde rotswanden, zoals in rotsspleten en op kliffen langs rivieren en watervallen, en op oude, vochtige muren. In tegenstelling tot het echt venushaar komt hij echter ook op silicaatrijke gesteentes voor, zoals op graniet.

Voorkomen

Het fijn venushaar komt van oorsprong uit tropisch Zuid-Amerika, maar is ondertussen door de mens omwille van zijn decoratieve waarde, ook over andere tropische streken verspreid, zoals in Hawaï en tropisch Afrika.

De soort is in Nederland verwilderd aangetroffen op oude muren, zoals in Delft en mogelijk in Utrecht.

Verwante en gelijkende soorten

Het fijn venushaar kan gemakkelijk verward worden met het echt venushaar (Adiantum capillus-veneris), dat ook nogal eens verwilderd wordt aangetroffen op oude muren.

Het duidelijkste verschil zijn de nerven van het fijn venushaar, die tussen de tandjes op de bladrand eindigen, terwijl die van het echt venushaar in de tandjes eindigen.
