 base, 3— 10 in. highj glandular-puberulent: leaves ovate to ovate-lanceo- 

 late, % — 1 in. long, 3 — 5-nerved, entire or sparingly toothed, short-

 angled. Style glabrous; stigma bilamellar. Capsule oblong-ovate, 

 acuminate, chartaceous, dehiscent by the upper suture, and to just past

 Seeds many, minute, favose-reticulate and glandular. 



1. M. pilosa (Benth.), Greene. Annual, 6 — 15 in. high, much branched 

 from the base, erect, leafy, villous with long viscid hairs, and with the 

 odor of narcotic solan aceous plants: leaves lanceolate to oblong-ovate, 

 entire, sessile: calyx slender-pedicelled, oblique, the upper segment 

 longest and about equalling the tube: corolla light yellow, 3—4 lines
