ORCHIDACEJE 



curved, rather stout, 1-1.5 mm. thick, portion up to the raceme 

 2.6-6 cm. long, provided with about three very small scarious 

 sheaths whicli are tubular at the base and infundibuliform above. 

 Rachis about 5.5-7 cm. long. Raceme densely many-flowered. 

 Bracts of the inflorescence up to 3.5 mm. long, triangular, acumi- 

 nate, cucuUate, reflexed in development. Pedicellate ovary about 

 6 mm. long, very slender, apparently lepidote. Flowers small,pel- 

 lucid in the dried specimen. Lateral sepals about 4 mm. long, 

 2.7 mm. wide across the middle, broadly ovate, oblique, apical 

 margins involute but when expanded forming an obtuse apex, 

 adnate to the spur, three-nerved. Dorsal sepal about 3.8 mm. 

 long, 2.6 mm. broad, ovate, rounded at the apex,cucullate, three- 

 nerved. Petals about 3 mm. long, 2 mm. broad, ovate, acute, 

 three-nerved. Lip with a conspicuous spur, three-lobed ; lateral 

 lobes small, oblong-falcate, extended backward, furnished on the 

 upper margin midway to the middle lobe with a minute tooth, 

 free portion about .8 mm. long, rounded at the apex; middle lobe 

 prominent, in natural position spreading, when immature ascend- 

 ing, in maturity slightly decurved, when expanded narrowly tri- 

 angular-lanceolate, upper portion sulcate-in volute and thickened, 

 just below the base of the mid-lobe within there is a more or less 

 distinct oblong fleshy callus; spur — dorsally measured from base 

 to apex — about 5-5.5 mm. long, narrowly cylindric, abruptly 

 dilated at the apex into a transversely ovoid porrect sac. Column 

 small, malleoliform. Anther pileate. Pollinia two, subglobose, at 

 the summit of a slender membranaceous cuneate-dilated stipe. 



Dwarf specimens are represented by Clemens 67 and 246. In 

 the former plant the leaves are subcoriaceous, the peduncle short 

 and a fresher flower shows suborbicular lateral sepals about 4 mm. 

 long and 3.5 mm. broad, dorsal sepal about 4 mm. long, and sub- 

 orbicular petals about 3.2 mm. long and 2.5 mm. wide.
