ORCHIDACEiE 



uous, about 3 mm. thick, closely invested by the fibrous rem- 

 nants of scarious tubular sheaths. Roots fibrous, rather sparse but 

 fascicled beneath the pseudobulbs, very long, simple or sparingly 

 branched above, more or less longitudinally sulcate, densely and 

 finely pubescent, about .8 mm. thick. Pseudobulbs apparently 

 remote, about 3 cm. long, very narrowly cylindric, somewhat 

 oblique, rugose- striate in the dried specimen, monophyllous, 

 surrounded by the fibres of sheaths, approximate to an old much 

 more slender pseudobulb about 2 cm. long. Leaf about 14.4 cm. 

 long, 2.6 cm. wide, oblong, acute or obtuse (tip broken off), 

 cuneate-narrowed to a sulcate petiole about 2.5 cm. long, coria- 

 ceous, the mid-nerve somewhat sulcate above and prominently 

 carinate beneath. Scape one-flowered (detached). Flower about 

 3.3 cm. across when expanded, purple tinged. Lateral sepals 

 about 1.8 cm. long, 1.05 cm. wide near the base, lance-falcate 

 and decurved, oblique, acute, dorsally carinate at the apex, sac- 

 cate at the base, about nine-nerved. Dorsal sepal about 2.25 cm. 

 long, 1.15 cm. broad, lance-ovate, acute and dorsally somewhat 

 thickened at the apex, concave, about nine-nerved. Petals about 

 1.65 cm. long, 6 mm. wide at the base where broadest, oblong- 

 lanceolate, complicate-acute and dorsally carinate at the apex, 

 very slightly falcate, five- to seven-nerved. Lip raised on the free 

 portion of the foot, in natural position semicircular-decurved by 

 a broad longitudinal fleshy papillose medianly channeled ridge 

 extending on the under surface from base to apex, cordate, sub- 

 acute or obtuse, about 6 mm. long from the center of the base to 

 the apex or 7 mm. long including the semi-orbicular basal auri- 

 cles, 6 mm. broad below, lower margins ciliolate. Column about 

 3.5 mm. long, very stout with a broad fleshy wing merging with 

 the foot. Foot broad, clavate, terminating in a free circinnate 

 stipe. Anther hemispherical, two-celled, granular-roughened.
