Antrophyum

provided by wikipedia EN

Antrophyum is a genus of ferns in the family Pteridaceae.[1] They are commonly known as lineleaf ferns.[2]

Description

Like most other vittarioid ferns, members of the genus have simple, straplike leaves. Most species lack a costa (midrib), although a few have a partial one, and the leaves are generally more than 1 centimetre (0.4 in) wide. The leaves have netlike venation, with three or more rows of areolae ("gaps" in the net of veins) on either side of the midline. Linear sori are borne along the veins throughout the underside of the leaf. Paraphyses (miniature hairs) are present on the sori (separating the genus from Polytaenium); the cells at the tips of the paraphyses may be spherical or slender, and spores are trilete. (By comparison, Scoliosorus and Antrophyopsis always have spherical cells at the tips of their paraphyses, and monolete spores.)[3]

Taxonomy

The genus was first described by Georg Friedrich Kaulfuss in 1824. He included in it several species placed in Hemionitis by Carl Ludwig Willdenow, distinguishing them on the basis of their reticulate, indusiate sori sunken into the leaf tissue. The name means "growing from a cavity",[4] a reference to the growth of the sori from a groove in the leaf. In 1875, John Smith designated Antrophyum plantagineum as the lectotype for the genus.[5] Species include:[6][7]

The subgenus Antrophyopsis, containing the species A. bivittatum C. Chr., A. boryanum Willd., and A. mannianum Hook. (later treated in Scoliosorus), was elevated to a genus in 2016.[3]

Distribution

Most species occur in tropical Asia and the Pacific, but A. immersum and A. malgassicum are known from Africa and the Indian Ocean.[3]

Antrophyum ( Spanish; Castilian )

provided by wikipedia ES

Antrophyum es un género de helechos de la familia Pteridaceae.[4]​ Tienen una distribución Pantropical.

Descripción

Son helechos con hábitos de epífitas o raramente rupícolas; con rizoma suberecto a rastrero, y escamoso, generalmente oscurecido por raíces enmarañadas y densamente pelosas; raíces no prolíferas; pecíolo ausente o muy reducido; lámina linear o elíptica a oblanceolada, simple, entera, cartácea a carnosa, glabra, con idioblastos espiculares visibles en el haz; nervaduras areoladas, las aréolas alargadas, poligonales, sin nérvulos incluidos; soros alargados a lo largo de las nervaduras formando un patrón reticulado; parafisos ausentes o (en A. ensiforme y especies del Viejo Mundo) presentes, simples o ramificados, con o sin una célula apical agrandada; esporas triletes o monoletes; el número cromosomático es de. x=60.[5]

Antrophyum se reconoce por su nervación areolada y soros que siguen las nervaduras, generalmente formando un patrón reticulado. Las especies neotropicales fueron estudiadas por Benedict (1907, 1911), y la aplicación de varios nombres fue aclarado por Tryon (1964a).

Taxonomía

Antrophyum fue descrito por Georg Friedrich Kaulfuss y publicado en Enumeratio Filicum 197, 282. 1824.[5]​ La especie tipo es: Antrophyum plantagineum (Cav.) Kaulf.
