Var. fuscatum, sepalis petalisque intus fuscis. 
Collected in Venezuela by Mr. Birschell. Living flowering 
specimens were sent to us in March, 1856, by Messrs. Jackson 
and Sons, Kingston Nursery. It proves to be a variety of the 
Odontoglossum figured by us at Tab. 4272, the O. hastilabium 
of Dr. Lindley, with the sepals and petals of a uniform brown 
colour in the inside; instead of being green, with transverse 
brown lines. 
_ Descr. A large epiphytal plant. Pseudobulbs four to five 
inches tall, broad and compressed, furrowed, bearing two or more 
leaves at its extremity, which are linear-oblong, obtuse, subcori- 
aceous, not distinctly nerved in the recent plant, slightly keeled 
at the back. Peduncle, or scape, elongated, arising from the 
base of a pseudobulb, and within a leaf springing from the root, 
panicled above. Panicle large, branched, many-flowered : at the 
setting of the branches is a small convex bract. Sepals and pe- 
tals much spreading, nearly uniform (the petals however being a 
little shorter and broader, and crisped at the edge and more in- 
curved), lanceolate, acuminate, subfalcate, subconduplicate, choco- 
late-brown within, outside green; brown at the margin. Lip 
JUNE Ist, 1856.
