ORCHIDACEyE 



nerves and many supplementary ones. Dorsal sepal about 6 mm. 

 long, 3.5 mm. broad near the base, ovate, obtuse, concave, indis- 

 tinctly seven-nerved. Petals about 7 mm. long, 2.5 mm. wide, nar- 

 rowly elliptic, subacute, three-nerved. Lip obovate-oblong in out- 

 line, three-lobed, about 12 mm. long, 6.2 mm. wide across the lat- 

 eral lobes, gradually cuneate-flabellate from the base to slightly 

 above the middle, then abruptly contracted to form the sub- 

 quadrate middle lobe; lateral lobes shallowly triangular with a 

 rounded or subtruncate apex; middle lobe bilobed to about the 

 middle, with semi-orbicular spreading lobules about 2.5 mm. 

 long, which are separated by a broad sinus provided at the base 

 with a minute blunt tooth ; two high, thin, parallel keels extend 

 from the base of the lip to the center of the middle lobe, where 

 they converge slightly toward a short median verrucose ridge 

 which extends from the base of the middle lobe nearly to the 

 sinus. Column short, provided with a broad upwardly curved 

 foot. Anther subglobose, two-celled, with ciliolate margins. 



Dendrobium bicarinatum is vegetatively very similar to D. 

 Eurorum Ames, which, however, has differently colored much 

 smaller flowers with different lip characters. D. .schist oglossum 

 Schltr. differs from D. bicarinatuin in its broader pseudobulbs 

 and floral details. From a photograph, D. appendiculatum Lindl. 

 is apparently a near ally, but the pseudobulbs appear broader 

 than in this plant.
