ANNALS OF ROYAL BOTANIC GARDEN, CALCUTTA. 
rounded at the apex and attenuated into the persistent style, reticulately veined, more or less hairy. 
Seeds obpyramidal, three-sided, about 2 mm. long; testa black; wrinkles conspicuously scariose. 
This is & species of the second rank; it is, however, closely allied to the group of forms included 
in subspecies II, but somewhat more distantly related to А. palmatum. 
Subspecies II. 
FEROX PROPRIUM (A. feroz, Wall); stems simple below, branched or simple 
upwards; leaves mostly suborbicular or ovate, more rarely reniform; flowers not musky; sepals variously 
coloured; helmet vaulted, rarely navicular; nectaries s'ightly or distinctly recurved upwards, often hairy ; 
spur usually conical with more or less recurved capitate apex, rarely cylindrical and obscurely capitate 
or subglobose; labellum oblong or spatulute, 3—4 the length of the spur, emarginate or bilobed ; follicles 
13—26 mm. long; seeds broadly obpyramidal, with broad scariose transverse wrinkles.
