ODONTOGLOSSUM TRIUMPHANS. 
[PuaTe 58.} 
Native of New Grenada. 
Epiphytal. Pseudobulbs ovate oblong, two to three inches in length, furrowed 
when old, diphyllous. Leaves oblong-lanceolate, acuminate, narrowed to the base. 
Scape arising from the base of the pseudobulbs, elongate, the inflorescence racemose, 
the flowers having longish internodes between them, and the pedicels each furnished 
with a small triangular bract at its base. Flowers large, handsomely spotted ; 
sepals oblong acute, narrowed to the base, deep golden yellow, marked for three- 
fourths of their length with transverse spots and blotches of rich brownish crimson ; 
petals similar in form and colour, somewhat broader, the margins lobulate or 
sinuate-dentate; lip clawed, the limb fiddle-shaped, apiculate, with the point 
recurved, the margin denticulate, the basal half white with yellow crests, and the 
anterior portion of a rich brownish crimson, narrowly edged with yellow, the claw 
bicarinate, the keel running out into crests on the disk, with a pair of larger 
faleate crests interposed. Column white, semi-terete, curved at the tip, with a 
rhombic minutely erose wing. :

The varied phases of beauty which are met with in the genus Odontoglossum 
are quite overwhelming; indeed so many of the species are really fine plants that 
to describe and illustrate all that are deserving would alone be a heavy task. We 
have now, at least, before us a species of the O. luteo-purpurewm group which is 
quite distinct, O. triwmphans, which we may observe is one of the most useful to 
cultivators, since it mixes up so well and forms so fine a contrast in colour with 
the forms of the O. Alexandre type. The particular variety we now illustrate, and 
which is a very remarkable one, was kindly sent us by E. Wright, Esq., Gravelly 
Hill, Birmingham, who has been cultivating Orchids for many years, and who has 
also sent us blossoms of many other beautiful species. The spike of O. triwmphans 
here represented was, it will be seen, a very fine one, having splendidly marked 
and showy flowers. There are many varieties of this species, some of them being 
lighter in colour than others; in fact there is an almost endless variation among 
the imported plants owing no doubt to the chance intercrossing of the parents, 
which has been effected by insects in their native country, where so many of them 
are found in contiguous spots. Our home cultivators too are taking a hint from 
the insect world, and doing much service to floriculture by hybridising some of the
