jection to it. The flowers, however, when gathered are 
handsome. 
186, PLEUROTHALLIS gelida; folio oblongo carnoso concavo basi atte- 
nuato caule tereti laxé 1-ochreato eequali v. longiore, spicis geminis erec- 
tis secundis folio subsequalibus e spatha brevi univalvi exsertis, floribus 
cylindraceis, sepalis carnosis intus pilosis lateralibus semiconnatis, pe- 
talis minimis glabris subrotundo-oblongis apice denticulatis, labello 
etiam breviore lineari cuneato bilamellato apice rotundato plano, co-

A plant with all the habit of Pl. racemiflora, but the 
spikes appear in pairs, and are hardly so long as the leaf, 
and the structure of the flowers is different. The whole 
plant is fully a foot high. Messrs. Loddiges obtained it from 
Jamaica. 
187. PLEUROTHALLIS sicaria; folio oblongo angusto plano in caulem 
tripld longiorem triquetrum canaliculatum deorstim attenuatum angus- 
tato, pedunculis brevibus 2-3-floris cernuis aggregatis, sepalis lineari-lan- 
ceolatis patulis chartaceis lateralibus ad apicem usque cohzerentibus sed 
facilé separabilibus, petalis ovalibus acutissimis serratis, labello lanceo- 
lato acutissimo bilamellato utrinque unidentato, clinandrio serrato. 
A native of Trinidad. In habit this species is most re- 
markable, its stem being exactly like a bayonet blade (sica) 
with the point downwards. It grows nearly a foot high. 
The flowers are greenish yellow with pale purple stripes along 
the sepals, much deeper stripes on the petals, and none at all 
on the labellum. 
188. PLEUROTHALLIS fragilis ; folio ovato-oblongo plano carnoso caule 
compresso canaliculato dupld breviore, pedunculis aggregatis brevibus 
(2-floris) folio adpressis, floribus carnosis fragilibus glaberrimis, sepalis 
lateralibus ad apicem usque coherentibus supremo lineari recto, petalis 
cuneatis apiculatis columnee apice denticulate subzequalibus, labello 
lineari apice rotundato basi utrinque paululum dilatato et denticulato 
superficie leevigata. 
This little plant has the habit of P. prolifera; but its 
leaves are flat, not folded together, and it is not proliferous. 
The flowers are bright orange-yellow, and very brittle, like 
wax; with a double row of minute purple dots along the 
middle of the labellum. Messrs. Loddiges have obtained it 
from Rio (11).
