1155.” It seems more than likely that the specimen referred to was 
Linden’s 1155 from Southern Mexico, which is, in fact, O. glanduliferus, 
while Fendler’s 1155 -is, at least in the Gray Herbarium, a piperaceous 
plant.

foliis alternis graciliter petiolatis ovato-lanceolatis inciso-serratis vel etiam 
profunde trilobatis tenuibus 1-2.5 cm. longis 5-12 mm. latis utrinque

March, 1898, E. Langlassé, no. 27 (type, in hb. Gr.). Vernacular 
name, clavellilo. In inflorescence, flowers, and achenes this species is 
much like F. Schaffneri, Gray, but it differs conspicuously in its chiefly 
undivided very thin and completely glabrate leaves, as well as in its glab- 
rate petioles and peduncles. In F. Schaffneri the leaves, which are of 
firm texture and somewhat grayish green with a fine permanent glandular 
puberulence, are regularly cleft nearly to the base into three linear lobes.
