0. Schlieperianum.—A very useful species. In habit of 
growth and general appearance it resembles O. grande; 
but the flowers, though like those of that species in form, 
are different in colour; they are borne upon erect scapes,

with a deeper shade of the same colour, or almost reddish 
brown. A native of Costa Rica; introduced in 1856. It 
requires the same treatment as O. grande. Syn. O. /usleayt

0. tripudians.—A well-marked and free-flowering kind, 
supposed to be of hybrid origin. In leaf-characters it 
resembles O. Pescatorei. The spike is arching, rarely 
branched, and the flowers are 24in. across, chestnut-brown 
and yellow, the former colour being in blotches; lip white, 
with a jagged edge, sometimes blotched with rose. Intro- 
duced from New Granada in 1869. When wild it is said

usually blooms only in autumn. It is somewhat variable 
in the markings of the flowers, and is not always admired. 
It requires cool treatment.
