Myriopteris Notholaenoides
''Myriopteris'', commonly known as the lip ferns, is a genus of cheilanthoid ferns. Like other cheilanthoids, they are ferns of dry habitats, reproducing both sexually and apogamously. Many species have leaves divided into a large number of small, bead-like segments, the probable inspiration for the generic name. Hairs and/or scales are often present on both the upper and lower surfaces of the leaf, and their presence and appearance are useful in distinguishing between species. The genus is most diverse in Mexico, but species are found from southwestern Canada south to southern Chile, and one species is endemic to southern Africa. Description No single morphological character divides ''Myriopteris'', as presently circumscribed, from the other cheilanthoids. Convergent evolution in arid environments is thought to be responsible for widespread homoplasy in the morphological characters traditionally used to classify this group. While small, bead-like ultimate segments are associat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Myriopteris Wootonii
''Myriopteris wootonii'', formerly known as ''Cheilanthes wootonii'', is a species of fern in the Pteridaceae family (subfamily Cheilanthoideae) with the common name Wooton's lace fern. Description ''Myriopteris wootonii'' grows fronds from a long creeping rhizome with tan to brown scales. The frond (leaf) is 10-20 cm long and 2-3 cm wide with a narrow stem (stipe) 1-2 mm thick. The leaf blade 3 to 4-pinnate and the leaflets are small and nearly round. Their abaxial (lower) surface is concave and densely covered with cilia and lanceolate-linear scales, and their adaxial (top) surface is glabrous. The leaf viewed from above has the general appearance of a flat array of tiny green pebbles, an appearance that is shared by several other ''Myriopteris ''Myriopteris'', commonly known as the lip ferns, is a genus of cheilanthoid ferns.
