base. Leaf on the old bulbs solitary from the apex of the 
bulb, broadly-lanceolate, acute, attenuated at the base, 
between membranaceous and coriaceous, about seven-nery- 
ed. On the very young pseudo-bulbs, before these are 
fully formed, the leaves are two and three. Scape from the 
base of a young pseudo-bulb, pendent, flowering almost 
from the base. Flowers large, handsome, rather distant. 
each with a broad, concave, heart-shaped bractea at the 
base. Sepals oblong, concave, combined at the base, and 
decurrent with the column, erect at the back of the column. 
Petals linear-lanceolate, arising from the base of the united 
sepals, deflected, the lower (or interior) margin inflected, 
scarcely unguiculate. Colour of the petals and sepals green- 
ish, tinged with purplish-red. Lip erect, almost appressed 
to the column, whitish, oblong, grooved, three-lobed, mid- 
dle lobe notched ; all of them serrated : within the lip dotted 
with red, striated in the middle; near the base, and at the 
union of the lobes, is a bifid serrated scale. Column semi- 
terete, white, freckled with red. Round the anther is a 
broad, winged, crenated border (the clinandrium). Anther-— 
case somewhat rhomboid, membranaceous, with two small 
cells beneath. Pollen-masses 2, oblong-ovate, each two-— 
lobed at the back, united by an oblong-cuneated gland, 
destitute of caudicula. The germen is attached to the 
back of the sepals, considerably above their united base.
