Dendrobium section Rhizobium is a section of the genus Dendrobium.[1][2]
Description
[edit]Plants in this section have thick, fleshy to terete leaves produced along a thin and wiry stem.[1]
The section was established in 1851 by John Lindley and Joseph Paxton. Species in this section was included in the genus Dockrilla, named after Alick Dockrill,[3] by authors including David Jones, Mark Clements and Stephan Rauschert for some species formerly included in the genus Dendrobium. A 2008 paper, based on a study the molecular phylogenetics of a wide range of related orchids, concluded that "the splitting of Australasian dendrobiums into various genera by other authors is excessive and unnecessary" moving the species back to the section Rhizobium.[4]
Distribution
[edit]Plants from this section are found in Australia, New Guinea, New Caledonia and Vanuatu.[1][5]
Species
