should be placed near to a damp wall of the house, and allowed to fasten 
itself there; this, with a frequent syringing during the hot summer months, 
will cause it to grow luxuriantly. For pot cultivation it will require a free 
drainage, and a compost of turfy peat, sphagnum, and small potsherds, and 
a liberal watering while growing, in a temperature of 65° to 70°. — Native 
of Brazil. 
299. Oncidium flexuosum var. viajus. This is only a larger variety of the 
former ; the colour of the labellum is a brighter yellow ; treatment and tem¬ 
perature the same. — Native of Brazil. 
300. Oncidium ciliatum. Plant pseudo-bulbous ; bulbs ovate, compressed, 
2 inches long and 1 inch broad; leaves single, linear, oblong, obtuse; flower- 
spike erect, flexuose, few-flowered; sepals and petals greenish yellow, spotted 
with purplish brown, or approaching to a sanguineous colour; labellum 
yellow. This species requires pot cultivation, with a free drainage, and a 
compost of turfy peat, sphagnum, and potsherds, with a moderate supply of 
water, and a temperature of 65° to 70°. — Native of Brazil. 
301. Oncidium pumilum. Plant destitute of bulbs ; leaves rigid, oval, 
oblique, erect; flower-spike 8 inches long; flowers yellow ; sepals and petals 
obovate, incurved ; labellum three-lobed ; lobes ovate, obtuse. This species 
is of a dwarf growth, but a free flowerer ; it requires pot cultivation, with a 
free drainage, and the same treatment and temperature as O.hians. — Native 
of Brazil. 
302. Oncidium citrinum. Plant pseudo-bulbous ; bulbs 4 inches long and 
a little more than 1 inch broad, of a pale green, scantily marked with brown; 
leaves in pairs, 1 foot long, crisp, erect; flowers produced upon a spike, of 
various lengths; sepals and petals yellow, spotted with brown; labellum 
yellow, but very pale. This is a fine species, but rather difficult to flower; 
it requires pot cultivation, and the same treatment and temperature as 
O. cornigerum. — Native of Trinidad. 
303. Oncidium stramineum. This species is very handsome, and well 
worthy of cultivation ; its flowers are of a pale straw yellow, spotted with 
purple. For treatment and temperature it may be referred to the last. — 
Native of Mexico. 
304. Oncidium leucochilum. Plant pseudo-bulbous ; bulbs 3 inches long 
and 2 inches broad, grooved, tapering a little towards the summit; leaves in 
pairs, 18 inches long and 2 inches broad; flower-spike 9 feet long, much 
branched; sepals and petals green, spotted with brown; labellum pure 
white. This species ought to be in every collection; its flowers are hand¬ 
some, and remain in perfect beauty for a great length of time; it requires 
pot cultivation, and a compost of turfy peat, sphagnum, and small potsherds, 
a good drainage, and a liberal watering while growing, with a temperature of 
from 65° to 70°. — Native of Mexico 
305. Oncidium Harrisonice. Plant pseudo-bulbous; bulbs subglobose, 
one-leaved, crisp, erect, of a whitish green; flower-spike 1 foot long, 
branched ; flowers not very showy ; the sepals and petals pale yellow, spotted 
with purple; labellum yellow, and spotted in the same manner. This spe¬ 
cies is not very handsome, but still is worthy of a place in a general col¬ 
lection ; it requires the same treatment and temperature as O. hians, to 
which it is very similar in habit. — Native of Brazil.
