* ONCÍDIUM citrínum. 
Lemon-coloured Oncidium. 
GYNANDRIA MONANDRIA. 
Nat. ord. OrcHIDEZ $ VANDER, Lindl. (Introduction to the Natural 
System of Botany, p. 262.) 
ONCIDIUM.—Supra, vol. 13. fol. 1050. 
O. citrinum ; pseudobulbis oblongis compressis, foliis ensiformibus rigidis scapo 
simplici brevioribus, sepalis petalisque labelli longitudine lineari-oblongis 
undulatis, labello cordato utrinque introrsüm arcuato apice dilatato subreui- 
formi, cristá 8-tuberculatá pubescente, alis minimis, stigmate orbiculari. 
Planta O. altissimo (fol. 1651.) vald? affinis et forte mera varietas. 
Diversa tamen videtur scapo non ramoso, floribus parum maculatis, sepalis 
petalisque minús acuminatis, cristá tuberculatá potius quam digitatá, demum 
alis minimis, et stigmate orbiculari nec angusto compressoque. 
A native of Trinidad, whence it wasintroduced by Messrs. 
Loddiges, in whose collection our drawing was made last 
November. Unfortunately the plant soon after sickened and 
died ; so that it is for the present lost to the country. 
It approaches very nearly to O. altissimum, figured at fol. 
1651 of this work; and is principally distinguished by the 
following characters. Its flowering stem is simple and not 
branched ; its flowers are of a pale lemon colour, very dis- 
tant from each other, and by no means so much spotted ; 
the crest of the lip consists of about eight warts, which are 
slightly downy, and not of nine smooth finger-like pro- 
cesses; its stigma is nearly orbicular, and not long and 
narrow, and the wings of the column are exceedingly small; 
and finally, both the pseudo-bulb and the leaves have a 
singularly yellow tint, as we are informed by Mr. George 
Loddiges. | 
Like the rest of the genus it requires a hot and damp 
stove.
