DESCRIPTION. 
PsEUDOBULBS ovate, two-edged, much compressed, dark-coloured, from one to two inches long, carrying a short 
solitary oblong-lanceolate leaf. Leaves very sharp-pointed linear-lanceolate, not half the length of the 
slender nodding graceful many-flowered Racemzs. Bracrs ovate, slightly angular, much shorter than 
the PEDICELS. SEPALS and PETALS nearly equal, lanceolate, acuminate, linear, two-thirds of an inch long, 
of a beautiful bright rose colour. Lip about same length as the petals, pale whitish rose, three-lobed, 
bilamellate at the base, side-lobes rounded, very small, intermediate lobe sharp-pointed, obcuneate. 
Corum standing forward, rounded, provided at its apex with three membranous wings. 
A charming little species long known by the specimens in the Lindleyan Herbarium. It was introduced— 
though in very limited quantities—by the Messrs. Backhouse several years ago, since which time it has always 
continued scarce. In Lindleys Herbarium the racemes are about the length of those represented in the 
figure, but in a specimen exhibited in 1872 by Mr. Linden the pseudobulbs, leaves, and racemes were nearly 
twice as large and as long as those in the Plate. The precise treatment that it affects has not yet been 
distinctly ascertained, but there can be no doubt that, being a denizen of high places on the mountain ranges 
in Peru, it prefers the coldest house.
