Description, 
Psevpo-Buxss very large, nearly globular, two or three inches in diameter, of an extremely 
hard texture, shining, emitting a number of long, slender wiry Roots, and surmounted by one, or 
more frequently, two, rigid, narrow, linear, somewhat acute, curved LEAVES, usually about a 
foot in length. Scare issuing from the apex of the pseudo-bulbs, erect, one and a half or two Seet 
high, branched for nearly its whole length in the cultivated plant, [but in wild specimens branched 
only at its extremity, where it bears a very dense compound head of flowers.) FLOWERS about an 
inch across, shorter than their PepuncxitES. SEPALS and PETALS nearly equal, acute, turned 
backwards, of a delicate pale greenish primrose colour ; the former are of an oblong-lanceolate form, 
the latter considerably unguiculate, and ovat-lanceolate, rather inclining to be spatulate. Lip 
3-lobed [the lateral lobes ovate and acuminate, pressed against the sides of the column, the central 
one almost orbicular,| of the same hue as the sepals and petals, but beautifully marked with 
numerous minute centripetal veins, united with the base only of the short, somewhat arched, 
CoLumn.
