Acrosorus
''Acrosorus'' is a genus of ferns in the family Polypodiaceae, subfamily Grammitidoideae, according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I). It is known from the Philippines, Malesia, Thailand, and the Pacific islands. Description Members of the genus have radially symmetric (rather than flattened) rhizomes, covered with hairless scales of uniform color. Their leaves may be partly cut, into lobes, or fully divided into pinnae. Their veins are at most a few times forked, and lack hydathodes. Each lobe or pinna of a fertile leaf bears a single sorus near the tip; the edges of the lobes or pinnae are rolled under and fused near the tip to protect the sorus. Leaf hairs may be single seta In biology, setae (singular seta ; from the Latin word for " bristle") are any of a number of different bristle- or hair-like structures on living organisms.

Polypodiaceae
Polypodiaceae is a family of ferns. In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), the family includes around 65 genera and an estimated 1,650 species and is placed in the order Polypodiales, suborder Polypodiineae. A broader circumscription has also been used, in which the family includes other families kept separate in PPG I. Nearly all species are epiphytes, but some are terrestrial. Description Stems of Polypodiaceae range from erect to long-creeping. The fronds are entire, pinnatifid, or variously forked or pinnate. The petioles lack stipules. The scaly rhizomes are generally creeping in nature. Polypodiaceae species are found in wet climates, most commonly in rain forests. In temperate zones, most species tend to be epiphytic or epipetric. Notable examples of ferns in this family include the resurrection fern (''Pleopeltis polypodioides'') and the golden serpent fern ('' Phlebodium aureum''). Taxonomy Two distinct circumscriptions of the family are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
