DESCRIPTION. 
了 SEUDOBULBS 2 Zo 3 inches long, smooth, ovale, somewhat compressed, 2- or 3-leaved. Lmaves 2 or 8 at the apex 
of the pseudobulbs, oblong, acute, shorter than the Scarr, which, rising from the base of the pseudobulbs, is bent 
down at its upper extremity by the weight of from 3 to 7 large and handsome FLOWERS. Bracrs only half the 
length of the ovary, embracing the flower-stem. Snuraıs 1} inches long. UDuraıs much wider than the sepals, and 
like them of an oblong form, waved at the margin, and a little recurved at the end, which is sharply pointed ; 
both sepals and petals are of clear membranous white, clouded (as the name implies) by a profusion of spots or 
blotches of a reddish-brown colour, which extend to nearly half their length. xe of the same texture and colour as 
the sepals, only that the brown blotches are broader, and that there is a patch of yellow on the claw ; its upper 
portion is of an ovate form, acute, with the margins very much torn ; its fleshy disk is hooded, or gathered into 2 
erect plates, with a pair of teeth attached in front. Cowumx very long, destitute of wings. 
It was at Munich, in the year 1835, that I first became acquainted with this fine Odontoglossum having, through 
the kindness of Professor Von Martius, been allowed to examine the rich collection of dried specimens that Baron 
Karwinski had then recently brought home with him from Mexico. Two years afterwards living plants were sent to me 
from Oaxaca, which happening to arrive in the midst of that remarkably severe winter 1837-38, I naturally expected 
would have been destroyed on their way ; so far, however, from this being the case, they appeared to have sustained little 
or no injury from the cold, and on being placed in a stove they soon began to push both roots and leaves. All went well 
so long as the temperature of the house did not exceed 70°, but when the winter had passed away and they had to face 
the intense heat at which the Orchid-houses of that period were ordinarily maintained, they then quickly lost their vigour 
and before a twelvemonth had passed were all gone, victims—like a multitude of other invaluable plants—to our then 
ignorance of the conditions under which alone the Orchids of cool countries could be expected to thrive ! 
Tam not aware that this plant ever flowered in this country until within the last year or two, certainly no figure 
of it has ever been published in any English botanical periodical; I have, however, found in a French work (the 
Illustration Horticole), under the name of O. mavillare, what is obviously the same as the plant represented in the 
Plate. I should myself have probably fallen into the same mistake as Professor Lemaire, had I not enjoyed the 
opportunity—which he unfortunately had not—of examining the original specimens in Dr. Lindley’s herbarium, and 
from which that able botanist drew up his description (in the Folia Orchidacea) of the two species. O0. marillare,
