280 MR. HENRY RIDLEY ON ORCHIDEZ AND 
The commonest species here, often densely covering branches 
of trees. The flowers are of a pale straw-colour. It is very 
floriferous and easy of cultivation.

This is a very distinct little species, and, though the flowers 
are small, is really pretty. The lateral sepals are so bent and 
connate at the base as to form a tube with a circular mouth, over 
which hangs the small violet lip. Their apices are separate 
and hang down, and are very slender and setaceous. The 
petals are rather long in proportion and strongly ciliate. The 
flowers form a perfect circle and look like a series of very small 
parrots’ heads, the lip representing the beak. They are (as 
indeed all the Cirrhopetala are) fertilized by a minute Dipteron, 
which usually settles upon the long pendent sepals and climbs 
up them till it reaches the lip upon which it sits, and when it 
has got beyond the balancing point of the lip is pitched off upon 
the column, where it receives the pollinia. I have seen one fly 
ride on the lips of all the flowers in an umbel in turn, but as a 
rule only one or two flowers at most are feriilized. 
C. Loncisstuum, Ridl., sp. nova. Rhizoma crassiusculum.
