59. DICEMA Lindl. 



Epiphytic herbs. Stems leafy, elongated, often pendulous, 

 covered with the leaf-sheaths and leaves. Leaves in two ranks, 

 somewhat membranous, spreading, short. Peduncles axillary, 

 solitary, each with one small flower, with two or three scarious 

 ample bracts, one above the other, near the base, the upper one 

 acute, the lower obtuse, and bracteoles generally two at apex 

 below the flower, the low r er broadly roundish, apiculate, the 

 upper linear, sometimes wanting. Sepals subequal, free, spread- 

 ing, lateral, slightly oblique, forming at the base with the foot of 

 the column a scarcely prominent chin. Petals similar to the 

 sepals, but smaller. Lip fleshy, fixed to the base of the column, 

 sometimes with a short claw ; blade sometimes broadening 

 ivpwards with angles produced sometimes into lobes or teeth, 

 concave, undivided. Column erect, semiterete, very stout, at 

 the base produced into a short or very short foot ; clinandrium 

 oblique, short, entire, rather broad. Anther terminal, opercular, 

 incumbent, very convex, imperfectly 2-celled ; pollinia 4, waxy, 

 ovoid, closely incumbent in pairs on themselves, without 

 appendage, affixed by a flat stipes, with a small gland. Cap- 

 sule ovoid or oblong, muricate or smooth, ribs only slightly 

 prominent.
