ADENONCOS VIRENS, Blume, Bijdr. p. 81. Mangrove swamps,

A common mangrove-tree epiphyte in Singapore. I do not 
see that it can belong to the genus JMierosaccus, to which it 
is referred by Sir Joseph Hooker in the ‘ Flora of British India.’ 
The base of the lip is a little depressed, but there is no spur. It 
has yellowish-green flowers with a strong scent of Friar’s balsam.

including var. aurea, with more yellow on the lip and on the base 
of the sepals ; and a pure white form with no yellow even on the 
lip.
