 length of the State. Stern from a quarter of an inch to inches high : corolla an inch 

 to one and a half inches long.

M. latifolius, Gray, I.e. Viscid-pubescent: stem a span high, loosely branching : leaves 

 all broadly ovate or oval, slightly petioled, membranaceous, 5-nerved at base, 9 to 12 lines 

 long : calyx in flower hardly oblique, in fruit very gibbous : corolla pink-purple, half to 

 three-fourths inch long ; the f unnelform throat as long as the tube : capsule narrowly 

 oblong, laterally sulcate. Guadalupe Island, off Lower California, Palmer. 



* * Capsule coriaceous or membranaceous, symmetrical : calyx equal at base, campanulate or

 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 U to 3 lines wide. California, in gravelly 

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



I -i 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: steins 

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



-H- 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 

 broadly campanulate tube, the anterior ones narrower ; throat of the corolla cylindraceous, 

 and the ample limb rotate (crimson with yellow centre) : capsule oblong-lanceolate, acute 

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

M. nanus, Hook. & Arn. Leaves from obovate or oblong to lanceolate : calyx-teeth 

 broadly lanceolate or triangular, acute (a line long), a quarter of the length of the tube : 

 corolla sometimes rose-purple, sometimes yellow : capsule with tapering apex rather 

 exceeding the calyx; the valves chartaceous. Bot. Beech. I.e. 378, (var. plur( floras);
