his handsome species is a native of Ecuador, whence it was originally 
introduced by Edward Klaboch, over fifteen years ago. No further 
particulars are recorded by Reichenbach, but the description appears 
been made from dried specimens. Living plants, however, appear to 
hâve been introduced. 
In 1878 a plant flowered in the collection of C. Dorman, Esq., of Lawrie 
Park, Sydenham, flowers of which were sent to Reichenbach by Messrs James 
Veitch and Sons, of Chelsea. This plant is believed to hâve been one introduced 
by Klaboch. 
Reichenbach compared the species with O. trifurcatum , Lindl., though 
it seems equally near O. superbiens , Rchb. f., in general character, while the 
crest of the lip somewhat resembles that organ in O. falcipetalum, Lindl., and 
O. serratum , Lindl., though larger and more prominent. By this character it 
may be readily distinguished. 
Like its allies, it is a scandent species, its stout rhizomes emitting a number 
of fleshy roots, and producing at intervals large oblong pseudobulbs, each 
with a pair of linear-lanceolate leaves at its apex, and about six similar ones 
at its base. The raceme is long and branching, and bearing numerous large 
and handsome flowers, whose general character is admirably pouitrayed in the 
annexed plate. The undulate sepals are of a light warm brown, the upper one 
very distinctly edged with bright yellow, the latéral ones slightly margined with 
the same colour. The petals are a little smaller, strongly undulate, light yellow, 
with numerous brown blotches on the lower half, which are often somewhat 
transversely arranged. The side lobes of the lip are dark purple, and the front
