 tis secundis folio subcequalibus e spatba brevi univalvi exsertis, floribus

A plant with all the habit of PI. 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; fobo oblongo angusto piano in caulem 

 triplo longiorem triquetrum eanaliculatum deorsum attenuatum angus- 

 tato, pedunculis brevibus 2-3-floris cernuis aggregatis, sepalis lineari-lan- 

 ceolatis patulis cbartaceis lateralibus ad apicem usque cobserentibus sed 

 facile 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 piano carnoso caule 

 compresso canaliculato duplo breviore, pedunculis aggregatis brevibus 

 (2-floris) folio adpressis, floribus carnosis fragilibus glaberrimis, sepalis 

 lateralibus ad apicem usque cohserentibus supremo lineari recto, petalis 

 cuneatis apiculatis columnar apice denticulatse subsequabbus, labello 

 lineari apice rotundato basi utrinque paululum dilatato et denticulato 

 superficie laevigata. 



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).
