Cyathea Dealbata
''Alsophila dealbata'', synonym ''Cyathea dealbata'', commonly known as the silver fern or silver tree-fern, or as ponga or punga (from Māori or ),The Māori word , pronounced , has been borrowed into New Zealand English as a generic term for tree ferns. It is also used to refer to tree fern logs when used for landscaping purposes. English speakers generally pronounce the word . is a species of medium-sized tree fern, endemic to New Zealand. The fern is usually recognisable by the silver-white colour of the under-surface of mature fronds. It is a symbol commonly associated with the country both overseas and by New Zealanders themselves. Description This fern is known to grow to heights of or more (though it occasionally takes a rare creeping form). The crown is dense, and mature fronds tend to be about long and have a silver-white colouration on the undersides. This distinctive silver colouration has made them useful for laying along tracks for night walking. The scales ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyathea Atrovirens
''Cyathea'' is a genus of tree ferns, the type genus of the fern order Cyatheales. The genus name ''Cyathea'' is derived from the Greek ''kyatheion'', meaning "little cup", and refers to the cup-shaped sori on the underside of the fronds. Description The species of ''Cyathea'' are mostly terrestrial ferns, usually with a single tall stem. Rarely, the trunk may be branched or creeping. Many species also develop a fibrous mass of roots at the base of the trunk. The genus has a pantropical distribution, with over 470 species. They grow in habitats ranging from tropical rain forests to temperate woodlands. Classification Conant ''et al.'' in 1996, concluded on molecular cpDNA and morphological evidence that a system of three clades – ''Alsophila'', ''Cyathea'' and ''Sphaeropteris'' was the most accurate reflection of evolutionary lineages within the Cyatheaceae, ''Alsophila'' being the most basal and ''Cyathea'' and ''Sphaeropteris'' derived sister groups. In the Pteridophyte P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cyathea Borbonica
''Alsophila borbonica'', synonym ''Cyathea borbonica'', is a tree fern endemic to Mauritius and Réunion. There are several natural forms and varieties. Description It reaches a height of roughly 2 meters, with a dark, hairy, scaly trunk. Its spreading leaves are dark green fronds. Each frond has a relatively small stem (Stipe (botany), stipe). Each leaf also divides only twice (bipinnate): * The central midrib of the frond (rachis) branches into many horizontal leaflets (Frond, pinnae). * Each pinna midrib bears many small leaflets (pinnules). Forms and distribution There are two natural Mauritius, Mauritian varieties, which occur mainly in the upland forest in the higher parts of the island, and are both endangered. There is one natural Réunion, Reunionese variety: * ''A. borbonica var. borbonica'' (Réunion) * ''A. borbonica var. latifolia'' (Mauritius), which bears an umbrella-shaped crown * ''A. borbonica var. sevathiana'' (Mauritius), which bears a funnel-shaped crow ...
