Gymnosphaera Poolii

	Gymnosphaera Poolii Gymnosphaera is a genus of tree ferns in family Cyatheaceae. Taxonomy The genus was originally described by Carl Ludwig Blume in 1828. It was frequently treated by later authors as a synonym of '' Cyathea'' or '' Alsophila''. In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), ''Gymnosphaera'' was left as a synonym of ''Alsophila'', as evidence to support its reliable separation was lacking. More recently, Shi-Yong Dong and collaborators proposed the revival and recircumscription of the genus based on additional phylogenetic evidence, an act subsequently accepted by other tree fern workers.

	Carl Ludwig Blume Charles Ludwig de Blume or Karl Ludwig von Blume (9 June 1796, Braunschweig – 3 February 1862, Leiden) was a German-Dutch botanist. He was born at Braunschweig in Germany, but studied at Leiden University and spent his professional life working in the Dutch East Indies and in the Netherlands, where he was Director of the Rijksherbarium (state herbarium) at Leiden. His name is sometimes given in the Dutch language form Karel Lodewijk Blume, but the original German spelling is the one most widely used in botanical texts: even then there is confusion, as he is sometimes referred to as K.L. Blume (from Karl). He carried out extensive studies of the flora of southern Asia, particularly in Java, then a colony of the Netherlands. From 1823 to 1826 Blume was Deputy Director of Agriculture at the botanic garden in Bogor (Buitenzorg) in Java. In 1827 he became correspondent of the Royal Institute of the Netherlands. In 1855, he was elected a foreign member of the Royal Swedish Ac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]

	Gymnosphaera Glabra ''Alsophila glabra'', synonym ''Cyathea glabra'', is a species of tree fern native to Borneo, western Java, Sumatra and the Malay Peninsula, where it grows in lowland swamp forest and montane forest at an elevation of up to 1500 m. The trunk of this plant is erect and 2–4 m tall. Fronds are bi- or tripinnate and 1–2 m in length. Characteristically of this species, the lowest pinnae may be significantly reduced. The stipe is very dark and bears basal scales. These scales are dark, glossy and have a paler margin and fragile edges. Sori are produced in groups of one to three on fertile pinnule veins. They lack indusia. Large and Braggins (2004) note that ''A. glabra'' is very similar to '' Alsophila gigantea'' and appears to form part of a complex that also includes ''Alsophila podophylla'' and ''Alsophila subdubia Alsophila may refer to: * ''Alsophila'' (moth), a genus of moth * ''Alsophila'' (plant), a genus of tree ferns {{Taxonomy disambiguation ...''.

It grows in forest, on stream banks, and in forest margins at an elevation of about 600 m or higher. , Plants of the World Online treated this species under the name ''Alsophila denticulata''. Description The trunk of the ''Alsophila acaulis'' plant is either prostrate or short and erect. Fronds may be bi- or tripinnate and up to 1.5 m in length.

	Gymnosphaera Commutata ''Gymnosphaera commutata'' is a Malesian species of tree fern found in wet and swampy forests. Description The trunk is erect and rarely taller than 3 m.

The stipe itself is dark and bears dark, glossy basal scales with thin, fragile edges. Fertile pinnules are notably smaller than sterile ones. Sori occur near the fertile pinnule midvein and lack indusia. Distribution and habitat ''Gymnosphaera commutata'' is native to the Malay Peninsula, central and southern Sumatra and Borneo, where it grows in acidic peat Peat (), also known as turf (), is an accumulation of partially decayed vegetation or organic matter.
