ORCHIDACE^ 



long, tubular, with ascending, long acuminate apices. Inflores- 

 cence 2.7 cm. long, the rachis closely white pubescent, in the nat- 

 ural state apparently erect or nearly so. Bracts up to 9 mm. long, 

 far exceeding the twisted ovaries, at the base concave and sheath- 

 ing the ovaries, lance-attenuate to a long subulate tip, margins 

 irregularly cellular-ciliate especially below, one-nerved, keeled 

 dorsally along the median line. Flowers about eleven, glabrous 

 except for a very narrow, irregular, pubescent zone at the sum- 

 nait of the ovary and base of the flower. Lateral sepals about 

 5 mm. long, 2. 1 mm. wide near the slightly saccate base, lanceo- 

 late, slightly oblique, obtuse, one-nerved. Dorsal sepal about 

 5 mm. long, 2.2 mm. wide at the base, deltoid-lanceolate, obtuse, 

 one-nerved. Petals about 4.5 mm. long, 1.8 mm. wide a httle be- 

 low the middle, lanceolate with a rather abruptly narrowed basal 

 portion, obtuse, one-nerved, somewhat oblique, of slightly thin- 

 ner texture than the sepals. Lip about 4.3 mm. long, oblong in 

 outline, from a deeply sulcate base extended forward at right 

 angles into a deeply grooved, almost conduplicate claw or hypo- 

 chil with strongly incurving sides, then dilated abruptly into a 

 reniform lamina; lamina about 1.4 mm. long, 2.5-3 mm. wide, 

 emarginate, bluntly apiculate, with more or less undulate, erose 

 margins ; claw or hypochil, when spread out, orbicular with two 

 prominent round, flat calli near the base. Column short, about 

 2.7 mm. long, with a conspicuous bifid rostellum, furnished with 

 a prominent chin on the anterior face. Anther large, lanceolate, 

 from a cordate, stipitate base slightly surpassing the rostellum. 

 Pollinia 2, sectile. 



This little plant is very closely related to Kuhlhasseltia White- 

 headii (Rendle) Ames, a native of the Philippine Islands; but the 

 Bornean plant differs from it markedly in the uniformly smaller
