florum A. S^ S. var. nov. A specie, haec planta floribus parvis 

 atque petalis apice rotundatis difFert. 



This plant differs from the species in the much smaller flowers 

 and broadly rounded petals. Lateral sepals about 1.25 cm. long, 

 1.35 cm. broad, triangular, very oblique, acute, forming a shal- 

 lowly saccate mentum. Dorsal sepal about 1 cm. long, 5.8 mm. 

 wide, lance-ovate, obtuse. Petals about 1.1 cm. long, 6 mm. 

 wide, elliptic, broadly rounded at the apex. Lip about 2 cm. 

 long, 1.3 cm. broad across the lateral lobes, cuneate-flabellate, 

 three-lobed; middle lobe largest, about 6 mm. long, 8.5 mm. 

 broad, suborbicular, very broadly rounded or slightly retuse ; five 

 parallel approximate keels are conspicuous just above the mid- 

 dle, as in the species.
