ONCIDIUM INTERMEDIUM. 
[Puate 345. ] 
Native of Cuba. 
An epiphyte, producing from a creeping rhizome small, dwarf pseudobulbs, these 
when young are completely enveloped in large membraneous sheaths, which are 
deciduous. The pseudobulb bears a single, erect, stiff, fleshy leaf, which is oblong- 
acute, and carinate beneath, upwards of a foot long, and light green on both surfaces. 
The scape is erect, somewhat flexuose, panicled, and many-flowered, attaining a 
height of from eighteen inches to two feet. Sepals entire, the dorsal somewhat 
rounded, the lateral spathulate, all yellow, spotted and barred with chestnut-brown ; 
petals same colour as the sepals, oblong and much waved at the edges; lip three- 
lobed, lateral lobes short, revolute, and obtuse; anterior lobe reniform, flat an 
spreading, the crest composed of two prominent Jobes, and three callosities. Colour 
clear yellow.

The genus Oncidiuwm is one of the largest in the whole Orchid family, and is 
exclusively confined to tropical America. It is closely related to Odontoglossum, 
the principal difference being found in the much shorter and broader column of 
Oncidium. This genus contributes largely to the decoration of our Orchid houses, 
as amongst the numerous species are to be found flowers of almost every shade of 
colour, although yellow in various shades predominates. Many of the species of this 
genus are found growing at considerable elevations in the mountain regions of South 
America, and there are doubtless many more undiscovered species yet to come, to 
give fresh encouragement to cultivators, and which will add to the varied display 
of our Orchid houses. The flowers of the majority of the kinds last long in full 
beauty, and many of them are eminently suited for personal decoration, or in a cut 
State for the embellishment of the dwelling-house. 
Our present subject belongs to the Miltoniastrum section of the genus, which 
contains many handsome species. It is an old inhabitant of our gardens, having 
been introduced from the Island of Cuba in the year 1837; but it is seldom seen, 
and, indeed, but little known amongst Orchid growers, and this latter fact, coupled 
with its beauty, has induced us to bring it to the notice of our subscribers. The 
Species flowered with us in the Victoria and Paradise Nurseries in the course of 
the present year, and our artist, Mr. J. N. Fitch, has produced a faithful repre- 
sentation of both plant and flowers,
