DESCRIPTION. 
PseupopuLes ovate, very similar to those of O. Hallii, bearing generally two stout sharp-pointed Leaves a foot 
or more long. Raceuz many-(6-18) flowered, half a yard or 2 feet long, rather drooping. Bracts small and 
triangular, 4 or 5 times shorter than the ovary. SEPALS 14 to 2 inches long, oblong-acute, narrowed at the 
base. 了 ETALS about the same size as the sepals, but broader and more acuminate, sometimes diversely lobed 
on either side like the sepals, nearly covered with rich chestnut blotches on a bright yellow ground. Lir 
white with deep reddish blotches at apex, shorter than petals, unguiculate, pandurate, partially connate with 
the column, toothed at the edges, bicarinate at base, provided with Crest consisting of two sets of falcate 
teeth, extending about one-third of its own length. Cotumy white, half the length of the lip, furnished 
with upright rhomb-like wings the edges of which are indented. 
This is a very fine species indeed, although it scarcely realizes the expectations excited by the figure in 
Pescatorea, whether as regards the size of the individual blossoms or their colour. In the fresh flowers the 
prevailing tone is a bright yellow, which serves as a foil to the rich brown or chestnut marking with which 
the sepals and petals are profusely covered, and which, though to a lesser degree, cover also the lip. But in 
Pescatorea the lip is represented as white, and as bearing at its upper extremity a rich blotch of bright purple 
which affords a beautiful contrast to the yellow and brown tints of the other parts of the flower. 
Probably the figure referred to may have been prepared from dried specimens and hence the mistake as to the 
colouring. 
There are many varieties of this species, some of the best of which were exhibited by Mr. Marshall of Enfield 
at a meeting of the Royal Horticultural Society as early as April, 1869. 
O. triumphans does not appear to be so plentiful in its native habitats as O. Halli, O. lutea-purpureum, 
and many other N. Grenada kinds that now swarm in our collections. The range of elevation within 
which it grows is nearly identical with that of 0. Malli, hence the same treatment is suitable to both. It is 
asily grown and flowers freely.
