The genus to which this plant belongs, as at present limited by Professor Lin prey, is rich in curious 
and beautiful species ;—more especially in Mexico, from whence several have been already received, and 
from whence many more have yet to follow. With respect to the distinctive characters of Oncidium, 
Odontoglossum, and Cyrtochilum, some excellent remarks will be found in Part V. of the Sertum Orchi- 
daceum (sub. Tab. XXV.), from which we copy the following :— 
«<'The true characters of Odontoglossum, and those by which alone it can be distinguished generally 
from Cyrtochilum and Oncidium, are, a long column, and an entire unguiculate lip, narrowing to the point, 
and furnished, at the base, with a pair of fleshy, entire, or fringed /amelle, in front of which stand two, or 
rarely three, teeth, or bristles. In this view of the case, Mr. Bateman’s Cyrtochilum Bictoniense will 
belong to Odontoglossum.” 
To the character of the genus, as here laid down by Dr. Linptey, the lip of the present species 
(being distinctly three-lobed) offers a remarkable exception; it conforms, however, so perfectly in other 
respects, that we cannot doubt its being a true Odontoglossum. 
The Vignette is taken from a figure of Mexican manufacture, in the possession of Mr. George 
Ackermann.
