0. OérstediimA small but exceedingly pretty species, 
with roundish, compressed pseudo-bulbs, bearing only one 
leaf, which is about 4in. long. The spikes are short, erect, 
one- or two-, rarely four-, flowered; flowers rin. across, 
full, pure white, except a yellow spot on the base of the 
lip, which is broad and irregular-edged. Introduced from 
Costa Rica in 1872. It flowers in the spring months. 
This little gem is found wild on mossy tree-trunks in 
constant moisture, where the temperature gets low at 
night. Under cultivation, it thrives when planted in 
shallow pans, and suspended close to the roof-glass in a 
cool, moist house.

Var. major has large flowers, of good substance, and 
usually produced in fours on a spike. 
0. Pescatoreii—This species is justly considered one of 
the most lovely of the whole genus. It has the habit of 
O. crispum, but the pseudo-bulbs are smaller. The flower-

bearing upwards of fifty, or even a hundred, flowers; the 
sepals and petals are snow-white, although varieties some- 
times occur in which a shade of rose is to be found; the 
lip is fiddle-shaped, white, blotched at the base with 
purplish crimson and yellow. The flowers are so chastely 
beautiful that we would choose this amongst the first in 
forming a collection; they last a long time in _per- 
fection. The plant blooms at various times, but usually
