380 MR. HENRY RIDLEY ON ORCHIDEEX AND 
This very rare little plant has deep red leaves and pink 
flowers. It is so closely allied to Thriaspermum that, in spite of 
its curious entire lip and apparent absence of column foot, it 
can, I think, hardly be generically separated. 
DENDROCOLLA. 
Dendrocolla, Blume, Bijdr., p. 291, partim (Sectio Forni- 
carta). 
Strictly speaking the species of this genus have no spur and 
sometimes not even a saccate portion to the lip; but their 
affinity with Thriespermum (which has the saccate lip of Aerides) 
cannot be doubted. The number of species described which I 
can certainly refer to this genus is but small; probably many 
more will be met with when more attention is paid to these 
small fugacious flowered plants. Besides the species described or 
mentioned below, the following should, I think, be referred 
here.

Of some of these species, the flowers are only partially 
described, and in some not described at all. The species seem 
to have a remarkable predilection for orchard trees, especially 
mangosteens, and some are rarely to be met with elsewhere.
