257. Oncidium bicallosum. Plant similar in growth to the above, though 
not so strong; flower spike 1 foot long, half pendent, producing from 16 to 
20 flowers, each of which is nearly 2 inches in diameter; sepals and 
petals yellow, having a slight tinge of crimson round the margin, and undu¬ 
lated ; the column is of a deeper yellow ; labellum yellow also, and two- 
lobed, with a pair of distinct tubercles for its crest, these being separated by 
a considerable space. It may be grown either on a billet of wood covered 
with sphagnum, or in a pot with a good drainage, and a compost of turfy 
peat, sphagnum, and small potsherds ; it does not require much water during 
any stage of growth. — Native of Guatemala.

long, and 8 inches broad, green, slightly spotted with purple ; flower spike 
3 feet long ; the sepals and petals of the flowers are pale green, blotched

green. It requires the same treatment and temperature as recommended for 
the others. — Native of Trinidad.

variety, and worth cultivation, the ground colour of the flowers being olive. 
The same treatment and temperature as for the others will do for this. — 
Native of Jamaica.

264. Oncidium sanguineum. Plant similar in growth to the last ; flower

of a blood red, which its name would imply. It does not differ in regard to 
treatment and temperature from the others. — Native of La Guayra. 
265. Oncidium Henchmaiinii. This species is of the same habit of growth 
as O. roseum, the flowers being more of a violet or rose-colour than the one 
just mentioned ; the treatment and temperature being the same. — Native of 
Mexico.
