 clasping petioles, oblong, acute at each end, closely dendculate-serratc, jiu- 

 berulent along the margin and veins, the lower ones opposite ; flowers sub- 

 sessile, the fruit pedicelled; petals much longer than the calyx ; stigma un- 

 divided. — SrJirch. ji. Lips. p. 147; Rcichenb. ic. rar. 2. t. 190; DC. I. c;

 leaves opposite, oblong-lanceolate, glandularly denticulate-serrulate; the mid- 

 dle ones more or less decurrent along (lie angles of tlie stem, the lower slightly 

 petioled; petals emarginate ; stigma clavate ; capsules })edicelled, minutelv

ft. giandidosum : stem simjile or nearly so, a little cree])ing at the base, 

 the angles slightly ])ubescent. — E. glandulosum, Lehm.! I. r. 



Canada! to lat. 64°, and Oregon! and N. W. Coast! On the high moun- 

 tains of Carolina, Michaux. — li Stem 1-2 feet high, nearly terete above. 

 Flowers small, rose-color. — Hooker remarks that lie cannot distinguish un- 

 branehed specimens of E. tctragonum from E. glandulosum, Lehm., and 

 Nuttall has observed that tiie mature capsules of the latter are not sessile, but 

 have slender pedicels. He thinks, however, that E. glandulosum is annual, 

 and inclines to think it distinct.

 berulent; leaves mostl}' opposite, lanceolate, acute, on very short petioles, 

 denticulate-serrulate, the veins often reddish; petals 2-cleft at the apex; stig-
