ONCIDIUM’ INCURVUM: 
INCURVED ONCIDIUMN. 
Oncrpium tncurvum ; pseudo-bulbis ovatis ancipitibus utrinque tricostatis diphyllis, foliis ensiformibus 
acutis, scapo elongato racemoso-paniculato, sepalis lineari-lanceolatis undulatis liberis, petalis conformibus 
incurvis, labelli laciniis lateralibus rotundatis nanis intermedia subrotunda concava acutdé, crista ovata de- 
pressa dimidia inferiore lineata superiore tricostataé, columna aptera. Lindley in Bot. Reg. Misc. 174. 1840. 
Habitat in Mexico.—Barxer, Ler. 
Description, 
PSEUDO-BULBS ovate, compressed at the edges, deeply furrowed, about an inch and a half high, 
bearing two or three rather short, acute, ensiform LEAVES. ScaPeE slender, rising to the height of 
three feet and upwards, branched (simply) at lax intervals throughout almost its entire length. 
SEPALS and PETALS nearly equal, linear-lanceolate, waved at their margin, white, elegantly blotched 
and spotted with lilac, shorter than the PETIOLES, which are an inch long. Lip three-lobed, the 
lateral lobes dwarf, rounded, the intermediate one mucronate, sub-rotund, hollow, with a crest of 
which the lower half is depressed and thrown into lines, while the upper consists of three elevated 
ribs. CoLumMNn destitute of wings. 
AN elegant addition to the genus Oncidium, for which we are indebted to Mr. Barker, in whose 
ample collection at Springfield it flowered for the first time in the early part of 1840. 
O. incurvum, like its nearest ally O. ornithorhynchum (figured at Tab. IV. of this work), is a native of 
Mexico, but apparently much less extensively diffused than the latter species, and much rarer even in its 
proper haunts. In the general aspect of their flowers a certain degree of similarity exists between the two 
plants, but their habit and the colour of their flowers are perfectly distinct, as is also the structure of the 
latter when carefully examined. Both are of the easiest culture. 
An elegant manufacture in gold and silver filigree is carried on at Lima and other towns on the shores 
of the Pacific, of which the butterfly delineated in the Vignette affords a pleasing example.
