DESCRIPTION.
PSEUDOBULBS oblong, very much compressed and very sharp at the edges, 11 to 2 inches long. LEAVES one
(•rarely if ever two) on each pseudobulb and broadly-oblong acute shorter than the scape. SCAPE and RACEME
sheathed at intervals with long keel-shaped membranaceous BRACTS, few or many flowered, simple or (imore
rarely) branched, from one to two feet high. SEPAXS and PETALS nearly equal, linear-lanceolate, extremely
acuminate, an inch or more long, greenish-yellow richly blotched with brown. Lip shorter than the sepals
heart-shaped, with a very acuminate slightly recurved apex, white with dark brown spots and a purplish
2-lobed callus at the base. COLUMN pubescent, club-shaped, almost wingless.
Though scarcely to be classed among the more attractive species, 0. cordatum is occasionally seen at our
Shows with branching scapes 2 feet high and flowers much more richly coloured than those in the Plate. It is
found both in Mexico and Guatemala (whence plants were sent to me by my lamented friend Skinner), but
always at high elevations.
It flowers in the early summer without any special treatment, except that it is perhaps more impatient
of water than some of its congeners.
