ONCIDIUM BRUNLEESIANUM. 
[PLatTEe 206. ] 
Native of La Plata. 
Epiphytal. Pseudobulbs linear ligulate, narrowed upwards, four inches long, 
slightly furrowed, dark green. Leaves two or three from the apex of the pseudobulbs, 
oblong ligulate, acute, broadish, furrowed. Peduncle radical, slender, pale purplish, 
bearing a spreading ovate panicle of exceedingly pretty flowers, which are remarkable for 
their strongly contrasting colours, the rachis in the upper portion being zigzag. 
Flowers crowded, the parts rather convergent than spreading, remarkable for the large 
rolled-up lip, which thus appears to have an oblong outline as seen on the plant; 
dorsal sepal obovate-obtuse, convex, almost boat-shaped, half an inch long, dull yellow, 
the lateral ones combined into an oblong bidentate form, rather smaller than the 
dorsal one, but of the same dull yellow; petals spreading, narrow oblong, half an 
inch long, pale yellow, faintly cross-barred with very light reddish brown; lip half 
an inch long, bright yellow, three-lobed, the deep side lobes erect, blunt-angled, 
and infolded so as to nearly meet at the top, the dorsal sepal closing over the 
opening, the centre lobe three-fourths of an inch wide, obreniform, recurved, of an 
intensely rich deep maroon, the spot passing down so as to become obovate, the 
disk marked with transverse maroon-crimson lines, provided with two blunt keels, 
and having one or two warty elevations at the side, and in front two stout conical 
projections, the whole crest forming a boat-shaped body with two anterior horns. 
Column yellow, half the length of the lip, hooded at top, and continued into two 
broad rounded undulated wings below.

This pretty new species of Oncidium is quite an acquisition among the small- 
flowering kinds, as‘ will be seen by our illustration. It is, moreover, one that takes 
up but little space, and this is generally an object with Orchid growers, as there are 
many species which claim a place in our cultivated collections. The Oncids are 
most useful for their brilliant colours, and, in the generality of cases, they have a 
graceful and effective appearance when intermixed with other Orchids. For our 
figure of this novelty we are indebted to the kindness of R. B. Lemon, Esq., 
Moat Lodge, The Avenue, Beckenham, in whose collection it flowered during the 
present year. : 
Oncidium Brunleesianum is a native of La Plata, having been gathered with a 
batch of Oncidium varicosum on the Rio de la Plata. It is an evergreen species, with 
dark green pseudobulbs about four inches long, and having the same appearance as those 
of O. pubes. Like that plant, ‘it produces branching panicles of gaily-coloured 
though small flowers, the sepals and petals being pale dull yellow faintly barred
