ORCHIDACE^ 



terminating in undulate setose tips in the dried plant, strongly 

 reflexed, more or less tomentose beneath, black in the dried spe- 

 cimen. Flowers extending nearly to the base of the peduncle, 

 crowded but often appearing somewhat lax in course of devel- 

 opment. Sepals densely white tomentose without, strongly con- 

 cave. Lateral sepals 4-4.5 mm. long, 2.8 mm. broad, obliquely 

 ovate, thickened at the subacute apex, forming a slightly saccate 

 mentum. Dorsal sepal ±4 mm. long, 2 mm. broad, oblong-ovate, 

 complicate-acute, thickened at the apex. Petals about 3.75 mm. 

 long, 1.7 mm. broad, spatulate-oblong, subacute. Lip about 

 4.1 mm. long, 5 mm. wide, deeply three-lobed, semi-orbicular in 

 outline; lateral lobes triangular, broadly obtuse, lateral margins 

 strongly incurved; middle lobe shallowly obtriangular or reni- 

 form, the broadly truncated anterior margin in alignment with 

 the apices of the lateral lobes, irregularly undulate, sharply 

 apiculate in the center ; a large, dorsally flattened, fleshy callus 

 situated in the center of the middle lobe and — in the dried speci- 

 men — overlapping the margin, bearing a smaller callus on the 

 back ; at the base of the lip there is a three-lobed farinose callus 

 with the middle lobe much the largest; two keels extend from 

 near the base of the lip to the sinuses between the lobes. Column 

 abbreviated, with a broad winged foot. 



In Clemens 76 occurs one peduncle over 28 cm. long, and in 

 an unnumbered collection of Clemens there is a lanceolate leaf up 

 to 2.55 cm. broad and a stem bearing six peduncles. The single 

 specimen found by Haslam shows a somewhat aberrant form 

 having more numerous peduncles (up to nine), generally nar- 

 rower petals and a transversely elliptic middle lobe of the lip 

 with a taller, apparently laterally flattened, apical callus. 



This species is very close to the Philippine Eria anceps Lea- 

 vitt, but more slender, the internodes shorter, the leaves thin-
