Dockrillia
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." "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."
