—Pvrsia: Mount Orizaba, altitude 3660 m., 14 Aug., 1901, 2G 
Pringle, no. 8560 (type, in hb. Gray). This is related to 0. Conzattii, 
differing in having much longer flowers, with segments of the calyx red 
instead of green. The falcate flowers spreading outwards resemble those 
of § Hemichroma, but the equally cleft calyx is that of § Huchroma. 
It is a showy species.

ina barranca below Trinidad Iron Works, altitude 1525 m., C. G. Prin 
no. 8935. Through the kindness of Dr. Prain, Director of the oyal 
ens at Kew, specimens under this number were compared with 
authenticated specimens in hb. Kew and reported as similar. There 18 
a tendency in the specimens in hb. Gray to have incised dentate of 
laciniate leaves. Bentham placed this in § Hpichroma on account of the 
somewhat ampliate calyx-limb. It is entirely unlike the other species 
in that section in habit, foliage, bracts, and flowers, and has the charac- 
teristic equally cleft calyx-divisions of § Luchroma, so in this synopsis 
it is included under the latter section. ?
