22 PITTONIA. 



laclniately toothed or pimiatijBcI : involucre nearly cylindrical, 

 f inch high, the inner series of bracts lanceolate-acuminate, 

 the outer all much shorter, but imbricated in several series : 

 ligules white ; summit of immature achenes with a sharply 

 denticulate border ; the whole pappus deciduoxis in a ring. 



From an imperfect specimen obtained at Tehachapi, Calif., 

 some years ago I had described the species as probably 

 annual. Last season I saw and collected it in the original 

 locality. The solitary stems arise from somewhat deep-seated 

 and apparently horizontally running perennial roots. The 

 species most related to it have tufted and somewhat decumbent 

 stems arising from a common tap root. 



MI3IULUS ScouLEKi, Hoot. Fl. Bor.-Am. ii. 100 ; Gray Syn. 

 Fl. Suppl. 448. This tine species, supposed to be very rare, 

 is frequent in the woods of Wasljington, back of Tacoma ; 

 and I saw it in the herbarium of Prof. Henderson, at Port- 

 land, without a name. It is distinguished from M. gidtahis 

 by the filiform stolons by which as a perennial it is propa- 

 gated, and also by its narrower, usually cordate, always 

 callous-toothed leaves. The following alpine plant may pro- 

 visionally be referred to it. 



MiMULUS ScouLEKi, var. ciESPiTosus. Stems slender, tufted 

 and low, 1 to 5 inches high, mostly 1-tiowered, perennial 

 by numerous matted filiform or almost capillary stolons: 

 herbage purplish, glabrous or villous puberulent : leaves 

 ovate, cuneate at base and subsessile, slightly and remotely 

 toothed or entire, 2 to 5 lines long : flower terminal, long- 

 peduncled, large ; calyx 4 or 5 lines long, campanulate, the 

 orifice closed in fruit; corolla an inch long, deep yellow, 

 strongly bilabiate. 



Forming mats on the surface of wet rocks along the 

 margins and in the midst of alpine streamlets near snow on 

 Mt. Eainier, 20 August, 1889.
