Names
[family ADIANTACEAE]
Information
Terrestrial ferns with solenostelic or less often dictyostelicscaly rhizomes. Fronds spaced or tufted; stipes mostly dark, often shining, with U-shaped or variously dissected vascular strands, not articulated; lamina simple or 1–4 pinnate or pinnatifid, glabrous or pubescent to densely velvety, sometimes with branched hairs and occasionally densely scaly; veins free or anastomosing. Sori discrete or forming soral lines along the margins or along the veins, sometimes borne on special flaps which form pseudo-indusia; indusia sometimes formed from reflexed pinnule margins; paraphyses often present.
Range
As treated here the family contains about 20 genera and 450 species, mostly pantropical but with many species extending to the temperate regions.
Notes
Hardly any authorities agree on the taxa included in this family. Pichi Sermolli treats Negripteris in a separate family and restricts Adiantaceae to Adiantum alone, and refers the other genera to Sinopteridaceae (Cheilantheae) and elsewhere. R.M. Tryon in Kubitzki, Fam. Gen. Vasc. Pl. 1: 230 (1990) has an extended family Pteridaceae with the genera treated here scattered among subfamilies Taenitoideae, Cheilanthoideae and Adiantoideae (the latter containing only Adiantum). Others have treated Cheilanthes and Doryopteris in a restricted Pteridaceae e.g. Shieh in Fl. Taiwan ed. 2 (1975). The very wide view of Adiantaceae of Schelpe (Contr. Bolus Herb. 1: 44–86 (1969)) includes families dealt with separately in this flora: Parkeriaceae and Actiniopteridaceae (also included in the extended Pteridaceae of Tryon).
