Gymnosphaera Biformis
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. List of species , the following species are accepted in the genus as currently circumscribed by the Checklist of Ferns and Lycophytes of the World: *'' Gymnosphaera acrostichoides'' (Alderw.)

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] |
