ORCHIDACE.E 



three or more, very thin in dried material, ±6 cm. long, 4 cm. 

 wide, ovate-cordate, with a shallow basal sinus, slightly oblique, 

 obtuse, mucronate, five-nerved with additional fainter nerves, 

 the mid-vein and prominent lateral nerves more or less carinate 

 beneath. Petioles sulcate, ±1 cm. long. Rachis about 2 cm. long, 

 zigzag, bearing few flowers, glabrous. Bracts in natural position 

 spreading and conduplicate, when expanded about 9 mm. long, 

 7 mm. wide, broadly ovate, acute, papyraceous, three-nerved. 

 Flower spreading-erect, the lip erect, the sepals and petals con- 

 nivent and decurved-circinnate, about 1.6 cm. long from the base 

 of the spur to the apex of the lip. Sepals linear, obtuse, mucro- 

 nate, one-nerved. Lateral sepals about 1.1 cm. long, 1.7 mm. broad. 

 Dorsal sepal about 1 cm. long, 2 mm. wide. Petals about 9.5 mm. 

 long, 2.8 mm. broad, linear-lanceolate, obhquely rounded and 

 mucronate, three-nerved. Lip spurred, flabelliform, 1.3 cm. long, 

 1.1 cm. broad across the apex; claw cuneate, rather abruptly di- 

 lated into the limb, sulcate, at the base medianly papillose-thick- 

 ened and pubescent; limb flabellate,with undulate margins, when 

 spread out shallowly emarginate, provided, near the apex, in the 

 center with a cluster of verrucose papillae, those at the apical end 

 largest; spur subglobose-cylindric, about 4.5 mm. long, 3 mm. 

 broad, pubescent on the anterior wall near the base of the limb, 

 with a longitudinal groove extending along the dorsal surface 

 to the anterior wall, the course of this groove marked within 

 the spur by a thickened ridge. Column about 6 mm. long, rather 

 broadly winged especially above, with the apex obtusely triangu- 

 lar with shallow and irregular indentations. Ovary with six sharp 

 wings. 



Clemens 263 A shows much smaller plants with leaves ±4 cm. 

 long, 2.8 cm. wide, lip 1.1 cm. long, 8.3 mm. broad at the apex, and 

 with the apical cluster of papillae arranged in three lines. There
