Renanthera caloptera is a species in the family Orchidaceae. It was formerly the only species in the monotypic genus Ascoglossum, abbreviated Ascgm in the horticultural trade. It is endemic to Dinagat Island in the southern Philippines and is critically endangered by collection as an ornamental plant and habitat loss. Its flowers are a vivid purple.
The Royal Horticultural Society uses Renanthera caloptera for hybrid registration purposes.
Before that 2014 taxonomic revision, Ascoglossum formed several different intergeneric hybrids (nothogenera):
Renanthera bella · Renanthera coccinea · Renanthera imschootiana · Early blooming Renanthera · Renanthera monachica · Renanthera storiei · Renanthera
