Hab. in Guayana, Schomburgk. (hab. s. sp. comm. indefessus inventor.) 
A beautiful plant with flowers of a lively rose colour and 2j inches long. 
Mr. Schomburgk gives me the following note upon this plant made during 
his stay in Guayana. 
“ I found this pretty species at the Savannahs adjacent to the lake 
Capooey, Arabisee Coast of Essequibo, where it appeared to be in great 
abundance. It is from 3 to 5 feet high, its leaves lanceolate, acute, 
amplexicaul, marginate, smooth, entire; the scape terete and smooth; 
leaves and scape glaucous; the flowers in the bosom of the leaf. "There is 
a gland where the flowerstalk is connected with the scape. ‘Ihe sepals 
are recurved, greenish outside, lake coloured inside, the floral envelopes 
a lilac approaching pink ; at the base of the crested lip there are two 
ovate glands of a whitish colour; it is likewise remarkable for a hairy 
canal with which the column appears to be connected; The column is 
white and appears almost succulent. The tuber is oblong and as far as I 
have observed uni-gemmiparous.
