thick. Stems slender, slightly sinuous, longitudinally sulcate, 

 sub-densely clothed with reddish-brown hairs, especially the 

 younger portions ; internodes ±1.6 cm. long. Leaves ±4.5 cm. 

 long, 5.3 mm. wide near the base, distichous, ^\ddely spreading, 

 narrowly lanceolate to linear-lanceolate, long acuminate, at the 

 apex very obliquely bilobed with sharp acute teeth, subcoria- 

 ceous, many-nerved, the mid-nerve somewhat sulcate above, 

 three more or less conspicuous nerves beneath, provided with 

 infundibuliform, brownish-hairy leaf sheaths which are ±5 mm. 

 long. Flowers rising singly from one or more of the nodes above 

 the middle. Lateral sepals about 7.5 mm. long, 5 mm. broad, 

 linear-oblong, exceedingly oblique, complicate-mucronate, three- 

 nerved, carinate, connate ^\ith the column foot and paired sepal 

 forming a saccate mentum and an arcuate spur which is ±4.5 mm. 

 long. Dorsal sepal about 7 mm. long, 2.3 mm. broad, oblong, 

 compUcate-mucronate, three-nerved. Petals about 7 mm. long, 

 .8 mm. ^vide, narrowly linear, acute or acuminate, one-nerv^ed. Lip 

 issuing from the spur-shaped sack formed by the lateral sepals, 

 three-lobed, about 1.2 cm. long and 6 mm. broad across the lat- 

 eral lobes, in outline cuneate-spatulate, the entire lamina papil- 

 lose; claw long, narrow, involute; lateral lobes erect, about 

 1.5 mm. long, dentiform, narrowly triangular, broadly obtuse; 

 middle lobe about 4.5 mm. long, 4.5 mm. broad, suborbicular 

 from a broad base, more or less retuse, apiculate, verrucose, erose. 

 Column short, provided above with a fleshy broadly truncate 

 wing which has a slender apicule in the center, below soon uniting 

 with the walls of the lateral sepals. Anther subglobose, sulcate, 

 papillose roughened, two-celled. 



In Clemens 28A occurs one plant which is more than 48 cm. 

 tall.
