green, half embracing the base of the club-shaped germen. © 
Calyx-leaves or sepals three, broadly lanceolate, spreading, 
but also incurved, concave, the superior one the narrowest ; 
and with this the two oblong lanceolate petals are connivent. 
Labellum very patent, lying close within the lower sepals, 
shorter than they, plane, or with the sides slightly deflexed, 
glossy, and of a rather darker green, and more deeply 
spotted than the rest of the flowers, deeply trifid at the 
extremity ; the two lateral segments considerably acumi- 
nated ; the intermediate one shorter, thickened, and purple. 
Column porrected, rather short and semicylindrical, with a 
slender, acuminated, subulate point, bearing in front two 
long, acuminated filaments, diverging beyond the middle 
and lying close upon the labellum. Anther-case oval, with 
a subulate point corresponding with that of the column. 
For this beautiful and most interesting species of Cara- 
serum, the Glasgow Botanic Garden is indebted to Mr. 
Lockxnart, who sent the living plant from Trinidad. It 
produced its large spike of flowers in the month of May. 
Professor Linptry has already figured a species. of the 
Genus, (C. cristatum, Bot. Reg. t. 966.) which differed from 
all the then known species of Carasetum in the spreading 
character of the labellum, and in the manner in which the 
sepals are expanded ; but in every other respect, in its habit, 
_ foliage, inflorescence, and especially in the structure of its 
column, it entirely agreed with Caraserum. The same re- 
marks may, with equal propriety, be applied to the present 
individual, which is moreover, as a species, totally distinct 
from C. cristatum.
