Belongs within: Athyriaceae. Diplazium is a cosmopolitan genus of rhizomatous ferns with sori elongate along veins (Harden 1990). Characters (Harden 1990): Rhizome erect or short-creeping, thick, covered with dark brown or black scales. Stipes clustered, stout, erect; rachises grooved above, grooves confluent with grooves of secondary rachises; lamina membranous to more or less leathery, simple to 2-pinnate with… Continue reading Diplazium

Belongs within: Leptosporangiatae. The Salviniaceae are a family of small, free-floating aquatic ferns. There are two distinctive living genera, Azolla and Salvinia. Salvinia species have large leaves, about two centimetres long, covered in long papillae, whereas Azolla have small leaves, one or two millimetres long, that are imbricate in two rows (Harden 1990). Characters (Smith et al. 2006): Plants… Continue reading Salviniaceae

Belongs within: Leptosporangiatae. The Marsileaceae, water clovers and pillworts, are a family of semi-aquatic, rhizomatous ferns. Characters (Harden 1990): Semiaquatic ferns; rhizome creeping, often branched, covered with hairs. Sterile fronds either with four or two leaflets at apex of stipe or filiform, vernation circinate. Sori borne within thick-walled, nut-like sporocarp; sporangia bearing spores of two kinds. <==Marsileaceae… Continue reading Marsileaceae

Belongs within: Polypodiales.Contains: Acrostichum, Pteris, Vittariaceae, Adiantum, Cheilanthes, Pellaea. The Pteridaceae are a cosmopolitan family of ferns with abaxial sori lacking indusia or protected by a reflexed or revolute leaf margin (M. D. Windham). Molecular phylogenetic analysis suggests that the Pteridaceae may be paraphyletic with regard to the Vittariaceae (Schneider et al. 2004). The Pteridaceae also… Continue reading Pteridaceae

Belongs within: Polypodiales. The Aspidiaceae is a large but often poorly defined family of ferns. The separation or otherwise of this family from others such as Dryopteridaceae has often been contentious, but Wang (1965) pointed out the raised costa of the leaves in Aspidiaceae as a significant distinction. Members typically have round sori that may… Continue reading Aspidiaceae

Belongs within: Polypodiaceae.Contains: Grammitis. The Grammitidaceae are a mostly epiphytic family of ferns. Many species are found in montane cloud forests. Members typically bear scaled rhizomes and rounded, abaxial sori. Characters (A. R. Smith): Plants perennial, mostly small, on rock or commonly epiphytic [rarely terrestrial]. Stems long- to short-creeping or suberect, usually unbranched, bearing scales [rarely… Continue reading Grammitidaceae

Belongs within: Pteridaceae. Pteris, brakes, is a cosmopolitan genus of rhizomatous ferns producing sporangia in linear, submarginal sori (Harden 1990). Characters (Harden 1990): Rhizome tufted or shortly creeping, covered with scales. Fronds 1–4-pinnate; lamina glabrous or sometimes with jointed hairs; rachis deeply grooved; veins free or anastomosing. Sori linear and submarginal, true indusia absent, recurved margin of… Continue reading Pteris

Belongs within: Leptosporangiatae. The Dicksoniaceae are a group of mostly terrestrial (occasionally epiphytic) ferns, most of which are tree ferns though some have creeping rhizomes. They are distinguished from other tree ferns in the Cyatheaceae by having hairs rather than scales on the trunk. Members of the Dicksoniaceae are found in the tropics, as well… Continue reading Dicksoniaceae
