Renanthera elongata (in situ)

This widespread species grows to a really large size and needs plenty of space. The one pictured below is several feet long and flowering on the longest “vine” on a tree. A friend once found it growing as a terrestrial scrambling across an open exposed area so it’s been found both as a ground orchid as well as an epiphyte. The small red flowers are borne on a multi-branched inflorescence and last for roughly two weeks.
