 branched : leaves from spatulate-oblong to linear-lanceolate, 2 to 6 lines long : calyx-teeth 

 ovate or triangular, not equalling the oblong-ovate obtuse capsule : corolla crimson, with 

 filiform tube, small throat, and oblique limb 1^ to 3 lines wide. — California, in gravelly 

 soil of the Sierra Nevada, at 5-8,000 feet. 



-K- -1- Corolla ampler, half to fully three-fourths inch long,' funnelform, with widely spreading 

 limb and throat gradually narrowed downward into the included or partly exserted tube: stems 

 from an inch to a span or more high. (Species nearly related.) 



++ Calyx hardly at all oblique ; the teeth almost equal in length. 

 M. Bigelovii, Gray, 1. c. Leaves oblong ; the upper ovate, acute or acuminate : calyx- 

 teeth very acutely subulate from a broad base (2 or less lines long), half the length of the

 or acutish, a little exceeding the calyx; the valves membranaceous. — Eunanus Bigelovii,
