All terete leaved ''Dendrobium'' species from Australia and Papua New Guinea have been moved into a newly created genus, ''Dockrillia'', named after Alick Dockrill, a contemporary Australian orchidologist. Dockrillia are ephiphytic or lithophytic plants, and found mainly along the east coast of Australia. :"The genus was recently reinstated as distinct from ''Dendrobium'' based on absence of pseudobulbs, single fleshy leaf terminal on a short stem, multiflowered inflorescence arising from near the base of a leaf and flowers with a 3-lobed labellum. Pollination by native bees."〔''A complete Guide to Native Orchids of Australia, including the island territories'', p. 388. David L. Jones. 2006. New Holland Publishers, Frenchs Forest, N.S.W. 2086 Australia. ISBN 1-877069-12-4.〕 :"Although the name ''Dockrillia'' was established as far back as 1981, it is only in recent years that the name has been resurrected. The genus ''Dockrillia'' has been split off from ''Dendrobium'' and comprises the "terete-leaved" group of "dendrobes". This revision has been generally accepted in Australia. Species in ''Dockrillia'' are characterised by succulent leaves which are rounded in cross-section (terete) and which arise from a creeping rhizome. Currently about 28 species are recognised. ''Dockrillia'' is named after Alick Dockrill."〔(Australian Plants Online. "What is a ''Dockrillia''?" )〕 Current Situation: The claim that ''Dockrillia'' is generally accepted in Australia is disputed. The Australian Orchid Council (AOC) follows the Checklist of Selected Plant Families accepted nomenclature and the RHS Hybrid Orchid Registration system, both of which list ''Dendrobium'' as the accepted genus and Dockrillia as a synonym. The major orchid growers association AOC and the AOC orchid judging system as well as the Australian National body for Australasian orchids, ANOS accepts ''Dockrillia'' as a synonym. 〔AOC〕 There are about 29 species, 17 in Australia, with the others in Timor, New Guinea, New Caledonia, Vanuatu, Fiji, Samoa and Tahiti.〔''A complete Guide to Native Orchids of Australia, including the island territories'', p. 388. David L. Jones. 2006. New Holland Publishers, Frenchs Forest, N.S.W. 2086 Australia. ISBN 1-877069-12-4.〕 ''Dockrillia'' crosses readily with ''Dendrobium'' to make Dockrilobium. Most ''Dockrillia'' plants are easily propagated by rhizome division. == Selected species == * ''Dockrillia wassellii'', the Furrowed Pencil Orchid. * ''Dockrillia cucumerina'', the cucumber orchid has leaves shaped like little cucumbers. * ''Dockrillia linguiformis'' the tongue orchid - from Latin: ''lingua'' which means 'tongue', and ''formis'' which means 'shaped'. The thick and leathery leaves grow from a creeping rhizone, either as an epiphyte or as a lithophyte. * ''Dockrillia pugioniformis'', the dagger orchid, from the shape of its leaves. Plants can grow to very large specimens, often completely covering a large branch of a large tree. * ''Dockrillia teretifolia'', the pencil orchid, from the shape of its leaves. It has a pendulous growth and is sometimes known as the bridal veil orchid. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Dockrillia」の詳細全文を読む スポンサード リンク
