Acrosorus Sclerophyllus
''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 setae (bristles), single catenate hairs (consisting of chains of cells), or branched catenate hairs, with setae for branches. Taxonomy The genus was created by Edwin Copeland in 1906, to accommodate a group of ferns similar to '' Prosaptia'' and until then classified in ...

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. Animal setae Protostomes Annelid setae are stiff bristles present on the body. They help, for example, earthworms to attach to the surface and prevent backsliding during peristaltic motion. These hairs make it difficult to pull a worm straight from the ground. Setae in oligochaetes (a group including earthworms) are largely composed of chitin. They are classified according to the limb to which they are attached; for instance, notosetae are attached to notopodia; neurosetae to neuropodia. Crustaceans have mechano- and chemosensory setae. Setae are especially present on the mouthparts of crustaceans and can also be found on grooming limbs. In some cases, setae are modified into scale like structures. Setae on the legs of krill and other small crustaceans help them to gather phytoplankton. It captures them and allows th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Davallia
'' Davallia'' (deersfoot fern, hare's foot fern, shinobu fern, rabbit foot fern, ball fern) is a genus of about 40 species of fern. In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), it is the only genus in the family Davalliaceae, which is placed in the suborder Polypodiineae, order Polypodiales. Alternatively, the family may be placed in a very broadly defined family Polypodiaceae ''sensu lato'' as the subfamily Davallioideae. The family is sister to the largest family of ferns, Polypodiaceae, and shares some morphological characters with it.Karl U. Kramer. 1990. "Davalliaceae". pages 74-80. In: Klaus Kubitzki (general editor); Karl U. Kramer and Peter S. Green (volume editors) ''The Families and Genera of Vascular Plants'' volume I. Springer-Verlag: Berlin;Heidelberg, Germany. Species are epiphytic ferns, with fronds arising from long aerial rhizomes which grow on and over thick bark on trees or on rock crevices. Description Usually epiphytic or epipe ...
