It is not easy to refer this plant to any genus. In the form 
of the sepals and petals it resembles such a Vanda as V. insignis, 
Blume, but is not so firm in texture. The lip is quite distinct 
from that of any Panda. The spur opens between the two 
lateral lobes of the lip aud not at the base, and in this and the 
form of the lateral lobes it resembles Renanthera, but the mid- 
lobe is that of a Trichoglottis. At its base are two linear 
spreading pubescent lobes. In front it is pinched up and 
thickened like that of some Phalenopsis ; a groove runs along 
the ridge and ends in a raised portion, while the apex is deflexed 
so that the lip is thickest at the end. The column is longer and 
slenderer than usual in this group, and the pollen-masses are 
borne on an oblong pedicel ending in an unusually large disc.
