The present elegant and delicate species of Oncidiwm seems 
to have been introduced nearly at the same time (1847) both 
by the late Mr. Clowes and Messrs. Loddiges, and, it is sus- 
pected, from Mexico; but of that there is no certainty. It is 
rather a free flowerer in the stove, and our drawing was made 
at Kew from Mr. Clowes’s plant, in May, 1860. The lip is pure 
white, the rest of the flower pale yellow-green, spotted with 
orange-red on the upper side, chocolate-brown beneath. 
Duscr. Pseudobulé broad-fusiform, four to five inches long, 
purplish-brown, somewhat compressed, having at the base four, 
large, distichous, imbricating, carinated, and subequitant sca/es, 
of the same colour, the longest of them the length of the pseudo- 
bulb. This latter bears a large, membranaceous, solitary, obo- 
vato-lanceolate, acute /eaf from its apex, twelve to fourteen inches 
long, and three inches broad, striated, with prominent veins on 
the under side. Scape rather slender, a foot and more long, 
terete, green, arising from the base of the pseudobulb, and with- 
in the larger scale, eated with appressed, green, acuminated 
than a foot long, pendent, slightly com- 
igzag, slender. /owers moderately nume- 
sepals nearly uniform in shape and colour, 
very delicate and flaccid, sometimes a little 
es. Panicle
