An unobserved species, now first introduced by Mr. 
Griffin, who received the plant, represented in the annexed 
plate, from Trinidad. It flowered last December in the 
hothouse at South Lambeth, and was communicated to Mr. 
Brown, who has made it the foundation of the present ge- 
nus, to be placed next to Oncipium, from which it differs 
by a convolutely concave undivided taper-pointed label, a — 
corolla with the petals all distinct, a column with the two 
top-lobes converging convolutely (not extended), and by 
two furrowless or unindented pollen-masses (furrowed or 
indented in Oncipium). pene | 
A humble plant (about four or fiye inches high), with 
two or three upright lanceolate leaves rather longer than 
the 5-flowered stem. Flowers scentless, about an inch in 
diameter, subbilabiately stellate. Bulb green, oblong, ovate, 
above ground. So far we have taken from the drawing, 
having had no opportunity of seeing the plant; what fol- 
lows is from the Latin of Mr. Brown. Corolla dingy yel- 
low, marbled on the inside with brownish purple; petals 
distinct, spreading: /abel sessile, shorter than the petals,
