Ever since the first reports of in vitro asymbiotic seed germination in Laelia-Cattleya by Knudson [5] and shoot-tip culture in Cymbidium by Morel [6], several orchid species had been successfully propagated in vitro using different explants such as leaves, flower inflorescence, roots, and
pseudobulb [7-10].
The presence of the
pseudobulb may facilitate a slow reduction in the leaf water content and decline in water potential during a period of drought [1, 4, 5].
Epiphytic herb, 29 to 32 cm tall not including the inflorescences;
pseudobulbs clustered, subcylindrical, compressed, 5.5 to 20.5 mm long, 4.5 to 15 mm wide, green, clothed by 4 triangular to narrowly triangular sheaths, acute to acuminate, scarious-papyraceous, lacking a foliar blade, deciduous; leaf solitary, at the apex of the mature
pseudobulb, conduplicate, oblong to oblong-elliptic, acute, fleshy, 6 to 29 cm long, ca.
Leaves numerous, coriaceous, forming a dense rosette, leaf sheaths not forming a
pseudobulb, the old dry leaves remaining along the stem and covering it; sheaths ca.
A new vegetative shoot grows from the
pseudobulb formed in the previous season.
Mealybugs were also concealed and were primarily found at the base of each plant hidden within the roots and beneath
pseudobulb sheaths.

Pseudobulb 1-leaved, light green, ellipsoid to oblong-ovoid, strongly compressed, smooth but turning rough with age, 1.5-3 cm x 1-1.5 cm; covered at the base by 2-4 foliose, articulated, overlapping sheaths, with a blade similar to the leaves, the sheath 1.5-2 cm long, the blade 1.5-5.5 x 0.6-1.2 cm.
