blunt and fleshy. 
A very distinct species of Cleisostome, imported from some part of the East Indies, probably 
Moulmein, by Messrs. Veitch and Co. Tt is remarkable for its thick tough aloe-like leaves, and 
panicles of dense sea-green flowers, singularly enlivened by a rose or violet lip. The inflorescence, 
too, although, as is customary among Cleisostomes, consisting of small flowers collected into dense 
spikes at the end of the branches, has a peculiar curved or drooping appearance, by which the 
species may be known irrespective of its foliage. 
Sepals oval, blunt, nearly equal, spreading. Petals with a similar form and the same direction, 
but very much smaller. Lip with a blunt oblong spur, filled with honey, one-celled, and twice as 
long as the limb, of which the lateral lobes are very short and erect, and the middle one rounded, 
with a minute tooth near the base on each side, while the point is so much reflexed as to be hidden 
unless the lip is lifted up. At the base of the column stands the characteristic tooth in the form of 
a blunt fleshy process, partly closing up the entrance to the spur. The pollen-masses are four, very
