Reichenbach describes this as an interesting addition to 
our knowledge of Odontoglossa, allied to O. triumphans, but 
with smaller flowers, and as suggesting the suspicion that it 
might prove to be a hybrid between that species and 0. ¢ri- 
pudians : it however differed in the shape of the lip so much that 
he was obliged to abandon this idea. On the other hand, this 
justly celebrated Orchidologist speaks doubtfully of the specific 
value of O. preenitens in saying that it “ may prove as good a 
Species as O. nevadense.” : 
O. prenitens is a native of New Grenada, whence it was 
collected by Mr. Gustave Wallis for Messrs. Veitch, who 
forwarded the specimen here figured in April, 1875. 
Dxrscr. Pseudo-bulbs two inches long, narrowly oblong, 
slender, much flattened, with acute margins. Leaves six 
to eight inches long, recurved, narrow, linear-oblanceolate, 
acute, narrowed towards the base and there concave, nearly 
flat above, keeled at the back, dark green. Scape together 
with the raceme as long as the leaves, slender, inclined, six 
to eight-flowered, green ; bracts one quarter of an inch long, 
appressed to the pedicel, which with the ovary is from an 
inch to an inch and a half long. Flowers lax, two inches in 
diameter, of a bright golden yellow and shining surface, with 
May list, 1876.
