and two lateral petals iin. long, ovate, and_ pointed; 
two lower sepals partly united and pointing downwards; 
lip nearly 2in. long, 14in. broad, flat, slightly lobed, and 
having a pair of raised, reddish ridges running down into 
the base; column winged, tipped with orange. When 
planted in a basket or on a raft, and placed in a cool, 
moist house, this species grows freely, and blossoms profusely 
from April to June. It was introduced from the Organ 
Mountains, in Brazil, in 1837.

0. cornigerum.—An easily-grown, compact, free-flowering 
species, related, to O. curtum. Pseudo-bulbs sulcate, 3in. 
long, one-leaved. Leaf thick and fleshy, broadly ovate, 
4in. long, dark green. Flower-spike thin, about 14ft. long, 
branched and crowded with flowers on the upper half. 
Flowers bright yellow, with bands of red-brown, small, 
but sufficiently numerous to make a fine display; sepals 
and petals jin. long, ovate, incurved; lip fiddle-shaped, 
with long, narrow side lobes, and a pair of projecting, 
horn-like processes at the base. Grown in a basket, and 
suspended so that the spikes hang down over the sides, 
this plant is really attractive. It requires a position in 
the Cattleya-house, and plenty of moisture at all times. 
It blossoms in April and May. Introduced from Brazil in 
1829.

0. crispum.—An old favourite, and still one of the very 
best garden Oncidiums. It is easy to manage, blossoms 
freely, and is abundant enough to be always cheap. The 
pseudo-bulbs spring from a stout, creeping rhizome, and 
are broadly ovate, flattened, deeply furrowed, rough, and 
usually dark brown in colour. The leaves are in pairs, 
and are about gin. long by tlin. broad, leathery, deep
