Bulbophyllum siederi

A rarely recorded Sumatran epiphytic orchid in Bulbophyllum section Biflorae, described by Garay in 1999 from plants cultivated at the Vienna botanic garden. Almost nothing is published on its wild habitat. The care here is generalised from its section and from Sumatran forest conditions, and should be treated as a starting point.
