ORCHIDACE/E 



ascending, many-nerved. Inflorescences one to three, opposite 

 the bases of the upper leaves, about 2.5 cm. long. Rachis ascend- 

 ing or arcuate, zigzag, densely spreading brown pilose. Bracts 

 distichous, spreading or slightly reflexed, ±8 mm. long, 4 mm. 

 wide, ovate-lanceolate, acuminate, deeply concave, spreading 

 brown pilose without. Flowers small, sub-dense, densely brown 

 pilose without. Lateral sepals about 4.5 mm. long, 3-3.5 mm. 

 broad, ovate-triangular, dorsally keeled and greatly thickened 

 at the apex, oblique, falcate, forming a saccate mentum. Dorsal 

 sepal about 5 mm. long, 2 mm. wide near the base, lanceolate, 

 concave, thickened at the apex. Petals about 4.75 mm. long, 1 

 mm. wide, oblong-linear, falcate, obtuse or rounded above, thin, 

 very sparingly long ciliate. Lip three-lobed, 5.5-6 mm. long, 

 3.5 mm. wide across the lateral lobes, obovate-spatulate in out- 

 line ; claw rather stout with involute margins, gradually dilated 

 into the sharply reflexed lamina; lateral lobes semi-orbicular, 

 more or less prominent ; middle lobe reniform, almost as wide as 

 the lateral lobes, deeply bilobed into two suborbicular lobules 

 about 2 mm. across, a minute blunt apicule in the sinus ; a pair 

 of short dentiform keels rise in the center of the lip with a more 

 or less prominent farinose callus in the middle nearer the apex. 

 Column short and broad produced into a stout foot which is 

 almost 3 mm. long. 



A wide range of variability in vegetative parts and flowers is 

 manifest in this species. Clemens 373 shows shorter leaves which 

 are very oblique and bears evidences of four inflorescences, while 

 Clemens 291 shows inflorescences up to 4 cm. long. 



This species is extremely close to the Philippine Eria lagunen- 

 sis Ames, both vegetatively and in the contour of the lip ; the 

 Bornean plant, however, has flowers about three-fourths as large 

 with smaller differently shaped keels and longer, narrower bracts.
