chased at Mr. Skinner's sale, and which, if there is no 
mistake in the matter, must have come from Guatemala. It 
is, however, so exactly like specimens found in Popayan by 
Mr. Hartweg, that we cannot help suspecting some error. 
Its general appearance may be understood by its having been 
mistaken for a Trichopilia. Its flowers are produced in loose 
erect racemes, out of broad obtuse short membranous spotted 
bracts. The stalks and ovary are an inch and half long; 
the latter with three very stout and strong ribs. "The sepals 
and petals are a pale watery green, erect, linear-lanceolate, 
equal, faintly tinged with purple. The lip is cream-colour, 
rolled round the column at the base, to which it also is 
united at the lower end. The column has a singular fringed 
hood, overlying the anther, and a nearly vertical stigma, 
closed in by fleshy inflected cheeks. In these circumstances it 
differs from Aspasia, to which the genus is nearly akin. 
Mr. Hartweg found in the same country another species, of 
which and the present the foliowing are the technical cha- 
racters.
