ORCHIDACE^ 



furnished with one or more sterile bracts which are rarely oppo- 

 site. Bracts of the inflorescence about 9 mm. long, 3 mm. wide 

 below, lanceolate, long acuminate, concave, three-nerved, much 

 exceeding the pedicellate ovary. Raceme loosely about twenty- 

 flowered. Perianth segments connivent. Flowers fleshy, trans- 

 lucent in the dried specimen. Lateral sepals about 1 cm. long, 

 3 mm. wide below, lance-attenuate with the involute margins 

 producing long caudate apices, forming a saccate mentum below, 

 one- or indistinctly three-nerved. Dorsal sepal similar, about 

 8.5 mm. long, 1.5 mm. wide near the base, concave below. Pet- 

 als minute, about 2 mm. long, .7 mm. broad, oblong-lanceolate, 

 obtuse and minutely apiculate, one-nerved. Lip minutely clawed, 

 in the natural position sigmoid, about 3 mm. long, abruptly de- 

 curved in the middle with the apex slightly upcurved, the basal 

 portion membranaceous with the sides erect and conduplicate, 

 the anterior half very narrowly elliptic, acute, very thick and 

 fleshy; limb when expanded trilobed, margins particularly of the 

 epichil ciliolate, hypochil about 2.4 mm. broad, orbicular, con- 

 cave, medianly thickened and sulcate, bicallose at the base, a 

 keel extending across the concavity on the lower surface. Col- 

 umn very small, furnished with a pair of short triangular acumi- 

 nate arms and a gently unciform foot which is provided with an 

 erect or upcurved slender tubercle near the base. 



Clemens 168 shows an obtusely pointed leaf measuring about 

 15 cm. long and a scape about 26 cm. long. In Clemens 327 there 

 is a subacute leaf about 15.5 cm. long, and in Clemens 354- the 

 leaves average smaller than the type, especially in width (about 

 2 cm. broad). It is a noticeable fact that the flowers of all the 

 collections usually have strongly connivent segments and are 

 thus apparently immature. 



In habit this species suggests Bulbophyllum dasi/petaluml^olfe
