ORCHIDACEiE 



duo pseudobulbo approximati, leviter flexuosi, vaginis nonnullis 

 tubularibus inconspicuis instruct!. Bracteae inflorescentiae late 

 triangulares, subito caudatae, late patentes. Flores minuti; peri- 

 anthium connivens. Sepala lateralia triangulari-ovata, acuta, 

 valde concava. Sepalum dorsale persimile sed paulo majus. Pet- 

 ala elliptico-oblanceolata, obtusa vel subacuta. Labellum in po- 

 situ natural! deltoideum marginibus involutis, expansum ova- 

 tum, apice late rotundatum. Gynostemium minutum, processu 

 rostelli bifido instructum. 



Plant slender, graceful. Roots numerous, fibrous, flexuous, 

 inner portion conspicuously sulcate, ±.7 mm. thick. Pseudobulb 

 two-jointed, closely invested by a sheath that is articulated 

 above and apparently terminates in a leaf-blade ; lower portion 

 about 1.4-2.2 cm. high, ovoid to pyriform-cylindric, finely ru- 

 gose in the dried specimen; upper portion about 1.3-2 cm. high, 

 narrowly cylindric, finely striate, monophyllous. Leaf 10.7-20 cm. 

 long, 2.1-3.1 cm. broad, elliptic-oblong, acute at the apex, nar- 

 rowed to a conduplicate base, chartaceous, many-nerved, the mid- 

 nerve somewhat carinate beneath. Scapes about 21-36.5 cm. 

 high, two approximate to each pseudobulb, much surpassing the 

 leaf, spreading, gently flexuous or arcuate, provided with several 

 inconspicuous tubular sheaths that are sometimes imbricating 

 below, remote above. Raceme up to 14.5 cm. long, about 1.5 cm. 

 wide, densely many-flowered above, looser below. Bracts of the 

 inflorescence rigidly spreading, about 4 mm. long, 3 mm. wide 

 below, broadly triangular, with an abrupt caudate point, lower 

 margins erose, one-nerved. Flowers very small, about 3.2 mm. 

 long, perianth connivent. Ovary elliptic, about 5 mm. long. Lat- 

 eral sepals about 3 mm. long, 1.8 mm. broad, triangular-ovate, 

 acute and minutely complicate at the apex, strongly concave, 

 one-nerved. Dorsal sepal very similar, about 3.2 mm. long, 2 mm.
