Description
|
Erect or pendulous, epiphytic herbs with short or elongate, usually simple stems of very variable vegetative appearance, 5-30 cm. long. Pseudobulbs linear to elliptic-oblong, subcylindric to strongly ancipitous, usually rugose, 1.5-6 cm. long and .3-2.0 cm. wide, approximate and inserted at an acute angle on the stems, the truncate apices monophyllous, the internodes and bases enveloped in closely imbricating, papery bracts. Leaves coriaceous, ligular, obtuse or 2-lobed at the apex, 3-15 cm. long and .3-1.6 cm. wide, contracted below into very short, conduplicate petioles. Inflorescences slender, 1-flowered, often solitary scapes produced from the bract axils of the flush of new growth, or sometimes from the base of the current mature pseudobulb. Flowers usually of moderate size or small, white or yellow marked with dark red, or with a red lip, or entirely dark red. Sepals sub- equal, free, more or less spreading, linear-lanceolate to elliptic-lanceolate, obtuse, with a minute apicule or sometimes acute, 6-12 mm. long and 2-4 mm. wide, the laterals adnate to the foot of the column, forming a short, subacute mentum. Petals lanceolate to oblanceolate, acute, 5-10 mm. long and 1.5-3.5 mm. wide. Lip entire or obscurely 3-lobed near the apex, 6-12 mm. long and 3-6 mm. wide when spread out, the base articulated with the column foot, the lateral margins rounded and erect in natural position, the mid-lobe subacute to truncate and shallowly emarginate, about 1/3 the total length of the lip; the disk with a ligular, obtuse callus nearly equalling the lateral lobes. Anther terminal, operculate, incumbent, 1-celled.
