M. bicolor, Hartweg. 



Viscid-pubescent, a span to a foot high, simple or branch- 

 ed from the base : leaves linear-oblong or lanceolate, entire 

 or denticulate, an inch long, sessile; the upper shorter than 

 the peduncles: calyx purple-dotted, the epidermis covering 

 a framework of ligneous or pithy, broad ribs; teeth triangu- 

 lar-subulate, in maturity spreading: corolla § inch long; 

 upper lip clear white; lower yellow with dots of purple: 

 capsule oblong-linear: seeds roundish, smooth, whitish. — 

 PI. Hartw. 328; Gray, 1. c. 



The remarkable structure of the calyx in this rather com- 

 mon species of the Sierra Nevada, does not appear to have 

 been noticed heretofore. Also the lower lip is said to be 

 the white one, whereas it is the upper, in all that we have 

 seen, and it is so shown by Dr. Kellogg in a very correct 

 colored drawing in the possession of the Academy. 



-H- -M- Calyx not ribbed, scarcely angled: corolla subregular, 

 purple. 

 M. Palmeri, Gray. 



Viscid but scarcely pubescent, 4 — 10 inches high : leaves 

 lanceolate, mostly entire, sessile, shorter than the 1-i-inch- 

 long pedicels: corolla f inch long, ample funnelform, the 

 lobes spreading, emarginate : fruiting calyx 3 — 4 lines long, 

 lightly angled, the teeth short, broad and obtuse. — Proc. 

 Am. Acad. XII. 82, and 1. c.

M. androsaceus, Curran in herb. 



Minutely puberulent-glandular, 2 — 5 inches high, diffuse- 

 ly branching, very slender: leaves 3 — 6 lines long, ovate- 

 oblong, entire, obtuse, sessile by a broad, sometimes cordate- 

 clasping base: peduncles very slender, elongated: calyx 3 

 lines long, faintly angled, the broad teeth nearly truncate 

 with a mucronate point: corolla crimson, twice the length of 

 the calyx, the subequal lobes abruptly spreading, rounded 

 and entire: capsule oblong, shorter than the calyx.
