ORCHIDACEiE 



panduratum, utrinque in medio constrictum, in auriculas binas 

 dorsales falcatas obtusas extensum, parte anteriore in lobulos 

 binos approximates semi- vel suborbiculares abrupte dilatatum. 



Plant caulescent. Stem from the base of the plant to the base 

 of the raceme, ±23 cm. tall, erect or erect-spreading, regularly 

 flexuous or sinuous, entirely concealed by the leaf sheaths. 

 Leaves (measuring the outer margin to the leaf blade next 

 below) ±7 cm. long, (measuring the inner margin to the blade next 

 above) ±6 cm. long, ±1 cm. thick dorso-ventrally below, distich- 

 ous, equitant, ensiform, gradually narrowed to an obtuse or mi- 

 croscopically truncate apex, spreading-ascending, not incurved, 

 the uppermost and lowermost leaves markedly shorter than the 

 intermediate ones. Peduncle below the raceme about 1.4 cm. long, 

 striate, provided with an irregular whorl of lanceolate bracts, gla- 

 brous below, pubescent above. Raceme about 12 cm. long, 5 mm. 

 broad, arcuate; rachis densely pubescent. Bracts of the raceme 

 triangular to lanceolate, concave, deeply fimbriate, sparsely pu- 

 bescent without. Flowers minute, verticillate, rather dense, looser 

 toward the apex. Perianth reflexed. Sepals concave. Lateral 

 sepals about 1.25 mm. long, ovate, obtuse, mucronate. Dorsal 

 sepal about 1.25 mm. long, round-ovate, broadly obtuse. Petals 

 about 1 mm. long, ovate-oblong, acute. Lip about 1.4 mm. long, 

 1.1 mm. wide at the base and near the apex, pandurate, con- 

 stricted in the middle, extended back into two spreading, broadly 

 falcate, obtuse auricles, the anterior portion abruptly dilated into 

 two semi- or suborbicular lobules which are scarcely spreading, 

 but are sometimes slightly overlapping. Column short. Ovary 

 very densely pubescent. 



The material gathered by Clemens at Kiau consists of two 

 plants that are much smaller and less robust (one with a spike 

 up to 17.5 cm. long) than the type; the flowers are less ad-
