Adiantoideae
3-442.14.00English: Maidenhair ferns; Adiantoid ferns.
Name: adiantum comes from Greek, meaning unwetted.
Clades: Pteridaceae; Pteridales; Pterididae; Polypodianae; Pteridophyta; Plants.
Members: 1 genus, Adiantum; 250 species.
Region: south America, Andes, eastern Asia, China.
Habitat: prefers humus-rich, moist, well-drained sites; bottom land soils to vertical rock walls; epipetric, terrestrial or epiphytic in moist habitats.
Use: ornamental, on rock walls around waterfalls and water seepage areas.Plant theoryAdiantoideae is a subfamily in Pteridaceae. It is placed in Subphase 4. This needs confirmation.TaxonomyAdiantoideae is a subfamily in Pteridaceae. Adiantum is paraphyletic, monophyletic when Adiantum raddianum, and possibly a few other species, are removed.BotanyKeys: rachis often dichotomously branching; sori relatively small and discrete with sporangia borne on the false indusium rather than the leaf blade proper.
Fern.
Stem: dark, brown to black!!
Leaves: bright green, often delicately cut leaf tissue; rhachis dark, often black, often dichotomously branching; slender, shining black stipes.
Sori: submarginally; covered by reflexed flaps of leaf tissue which resemble indusia; dimorphism is subtle; relatively small and discrete with sporangia borne on the false indusium rather than the leaf blade proper.Subgenera • Homotypic
