orchids which contain pseudobulbs. The tribe contains two genera, '' Dendrobium'' and '' Bulbophyllum'', which are both among the largest genera of orchids, and are common in cultivation. Previously, other genera were included in the tribe, which are now subsumed in ''Dendrobium'' and ''Bulbophyllum''.

Features

''Dendrobieae'' are mostly small,

orchids. The roots are covered by velamen. There are usually pseudobulbs present, with leaves at the top; sometimes the species lacks pseudobulbs and the leaves are spread across the stem or the plant is leafless. The

flowers A flower, sometimes known as a bloom or blossom, is the reproductive structure found in flowering plants (plants of the division Angiospermae). The biological function of a flower is to facilitate reproduction, usually by providing a mechani ...

called for a review of ''Dendrobieae'' to be placed in the more monophyletic groups. Thus Bulbophyllinae was positioned earlier while

in its original position. He placed the genus Epigeneium in a separate monophyletic subtribe, Epigeneiinae, after ''Dendrobieae''. The genus ''Dendrobium'' is split further: The species of the section ''Oxystophyllum'' were placed under ''Podochileae'', the
