growth. The pseudo-bulbs are smooth, and shining light 
green. The leaves are thick, and darker in colour. The 
flowers, which are about 3in. across, and full in outline, are 
sometimes pure white, and sometimes (as in var. roseum) 
beautifully suffused with rose; they are borne on pendulous 
racemes, appearing about the months of May and June 
and remaining in full beauty for three or four weeks. 
From fifteen to thirty flowers, which are delicately lemon- 
scented, are produced in each raceme. The lip has a long 
claw, and is suddenly expanded into a broad, kidney- 
shaped blade. Unlike all other species, this pushes its 
flower-spike along with the new growth, the former usually 
appearing when the latter is about 2in. long. It is also 
exceptional in having pendulous racemes. It was _ intro- 
duced from Guatemala in 1840. Syn. O. pendulum.

Var. album has flowers wholly white, except the yellow 
crest on the base of the lip. 
Var. punctatum has rosy flowers, dotted with purple. 
0. Coradineii—A supposed natural hybrid, with the habit 
of O. crispum, producing arching scapes, bearing about 
ten flowers. The flowers are 3in. across, star-like, primrose- 
yellow, with large blotches of chestnut; lip shorter than 
the petals, paler, and with usually only one large blotch 
of red-brown in the centre. Introduced from New Granada 
in 1872. It usually blooms in winter if grown along with 
the cool kinds.

0. cordatum.—This has ovoid, compressed, shining green 
bulbs, each bearing a leaf 6in. to 8in. long. Scape erect, 
simple or branched, bearing few or many handsome flowers. 
Sepals and petals yellow, blotched and barred with deep
