Haplopteris Guineensis
''Haplopteris'' is a genus of vittarioid ferns, a member of subfamily Vittarioideae and family Pteridaceae. Description Like other vittarioids, the members of ''Haplopteris'' are epiphytes. The rhizome has a distinct upper and lower side, lacking radial symmetry, a characteristic that separates it from ''Radiovittaria''. Leaves are borne in two ranks in a single plane, and are usually simple, occasionally forked. The leaves have a distinct costa (midrib). Most species have netlike leaf veins which form two rows of areolae (the "gaps" in the net) on either side of the midline; two species bear a single leaf vein only. The linear sori, in most species, are confined to a commissural vein (paralleling the edge of the leaf margin and set just back from it, joining the ends of the netted veins); in the two species with a single vein, the sori follow that vein. The sori bear paraphyses (minute hairs) with a cell at the tip shaped like an inverted cone, separating it from ''Vittaria'' ...

Pteris Scolopendrina
''Pteris'' (brake) is a genus of about 300 species of ferns in the subfamily Pteridoideae of the family Pteridaceae. They are native to tropical and subtropical regions, southward to New Zealand, Australia, and South Africa, north to Japan and North America. 78 species (35 endemic) are found in China. Some species of Pteris have considerable economic and ecological value, such as Pteris multifida, Pteris ensiformis, Pteris vittata can be used for ornamental purposes; as a hyperaccumulator, Pteris multifida and Pteris vittata can be used to control soil pollution. Many of them have linear frond segments, and some have sub-palmate division. Like other members of the Pteridaceae, the frond margin is reflexed over the marginal sori. The outermost layer is the single layered epidermis without stomata. The cortex is differentiated into outer and inner cortical region. The vascular cylinder is an amphiphloic siphonostele. The term "brake", used for members of this genus, is a Midd ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
