Esq., who also imported it from Brazil. From both these 
establishments, where it flowers during the winter months, 
it has been obligingly communicated to me. At the time 
I described this plant in the Exotic Flora, I was not aware 
of its having been published two years previously by Dr. 
Nees von Esenseck in the work above quoted. I now 
gladly adopt his name. His plant differs in no respect from 
ours, save in the fewer and narrower leaves. I may here 
observe, that the flowers of the spike in the accompanying 
figure (taken from Mr. Surpnern’s specimen) being con- 
siderably advanced, the segments of the perianth are on 
that account more deflexed than in an earlier stage of per- 
fection, and their margin reflexed. Our figure 1, from 
Mr. Horsratu’s plant, represents the more perfect form of 
the flower. 
Descr. The bulbs and foliage of this plant are similar 
to those of the other species of the Genus: and the distin- 
guishing marks of the flowers are better understood by a 
reference to the figure than by words. They are, perhaps, 
the smallest of the concave-lipped species, and of an uni- 
form pale yellow-green colour, the inside of the lip only 
excepted, which is of a purplish-brown colour. The lip 
itself is superior, remarkably contracted at the mouth, the 
margin at the extremity destitute of teeth, the sides denti- 
culate. The sepals are ovate, concave, and as well as the 
petals directed downwards, so as only to enclose the lower 
part of the labellum with their concave bases, in age they 
are still more deflected, and the margins turned outwards.
