ORCHIDACE^ 



small. Lateral sepals about 4.5 mm. long, 2.25 mm. broad, lance- 

 ovate, apex thickened cucullate and obtuse, slightly oblique, 

 with three subapproximate nerves. Dorsal sepal about 5 mm. 

 long, 1.75 mm. w^ide near the base, lanceolate, obtuse at the 

 slightly thickened tip, with three approximate nerves. Petals 

 about 4.8 mm. long, scarcely 1 mm. wide near the apex, spat- 

 ulate-linear, gradually broadened from a very narrow base to 

 the rounded apex, one-nerved. Lip in natural position about 

 3.4 mm. long, 2.9 mm. broad near the base, triangular-lingulate 

 in outline; disc short-clawed, extended on each side, from a 

 broad rounded base, into a conspicuous fold then abruptly con- 

 tracted to about the middle from which point extended into an 

 ovate limb which is truncate at the apex with a small central 

 rounded callus. There is a large transversely oblong callus which 

 is situated, near the base, in the middle and just below the folds. 

 Column about 2 mm. long and nearly as broad at the base, 

 gradually narrowed from the base, with a pair of parallel por- 

 rect triangular rounded wings above. 



There are several rather near allies of this species. Liparis 

 pseudo-disticha Schltr. has leaves about equaling the flowering 

 peduncles and differently colored, smaller flowers with a larger 

 lip. L. GJellerupii J. J. Sm. possesses shorter pseudobulbs, a 

 scape which about equals the leaves and a differently propor- 

 tioned lip. It is vegetatively a much smaller plant than L. geel- 

 vinkensis J. J. Sm. The very similar L. lobongensis Ames has a 

 much larger callose lip and differently colored flowers. L. gau- 

 tierensis J. J. Sm. is a much larger species than L. lingulata.
