Oncrpium Janeirense. “Reichenb. fil. in Bonpl. Ap. 1, 1854.” 
A Brazilian plant, reared by Messrs. Loddiges from pseudo- 
bulbs received from Rio Janeiro. Dr. Lindley considers it iden- 
tical with his Oncidium longipes; but its flowers are so much 
brighter, and attractive for the size of the plant, that it is quite 
worthy of cultivation. It differs moreover in the form of the 
crest of the lip, which is accurately represented at our figure 2. 
Its flowers appear in April, and continue long in blossom. 
Descr. From a creeping cavdea, about as thick as a writing- 
pen, pseudobulbs arise in clusters, oblong, tapering upwards, 
sheathed with brownish scales, bearing two, linear, apiculated, 
somewhat fleshy /eaves, linear-oblong, tapering much at the 
base, apiculate at the point, bright green. Peduncle or scape 
slender, arising from between the leaves, bearing a raceme, three 
to four inches long, of several loug-pedicellate flowers. Sepals 
and petals all spreading, dark, almost blood-red-brown within, 
brownish-green on the outside ; superior or dorsal sepal spathu- 
late, the margins waved and reflexed, lateral sepals narrower, 
united at their base, deflexed. Zadel/um large in proportion to 
the size of the flower, bright, almost golden yellow, with a broad 
blood-coloured ring at the base surrounding the crest, three-
