 branched from the base, 3-16 inches high, soft pubescent throughout: 

 leaves thin mostly pinnatifld with the lobes again incised, or bipinnatifid, 

 some of the uppermost less cut or even entire and bract-like subtending

 ovate-lanceolate, acuminate: corolla light purple to pink, slender, 5-6 lines 

 long, 2-3 times as long as the clayx: stamens very unequally inserted: 

 ovules 1-3 in each cell. Common in open woods, Brit. Columbia to Cali- 

 fornia west of the Cascade Mountains. 



* * * Perennials with exserted and declined stamens. 



C. Mazama Coville Proc. Biol. Soc. of Wash, xi, 35. Glabrous or 

 with a few arachnoid viscid hairs on the stem and leaf-margins, the in- 

 florescence glandular- hairy : stems few to many from a slender perennial 

 tap-root, 6-15 inches high, usually simple : leaves oblong-lanceolate to 

 lanceolate, 1-2 inches long, acute at both ends, acutely and somewhat 

 laciniately 3-5-toothed toward the apex, the upper entire and sessile, the 

 lower often oblanceolate and petioled : inflorescence subcapitately cymose : 

 calyx commonly 4-5 lines long ; the triangular-lanceolate acuminate lobes 

 about as long as the tube, enlarging in fruit : corolla about 7 lines long, 

 deep blue to violet-purple, funnel form; the narrowly oblong- obovate obtuse 

 lobes 2-3 lines long : anthers and style slightly exserted : seeds linear-ob- 

 long, solitary in the cells. On Mount Mazama southern Oregon. 



C. debilis Greene Pitt, i, 127. Oilia debilis Watson. Minutely pu- 

 bescent or hirsute and viscid: stems loosely tufted, 2-8 inches long leafy 

 to the top : leaves pedately 3-7 -parted or the upper ones 3-cleft, attenuate 

 below to a petiole ; the lobes 2-6 lines long, linear-oblong, or the larger more 

 dilated and 2-3-cleft: flowers subsessile and solitary in the forks and axils : 

 calyx cylindraceous ; the short subulate teeth but half as long as the tube ; 

 corolla funnelform, 6-8 lines long, with elongated tube and deeply clet't 

 limb, light purple to blue: cap3ule a line long; the cells 1-seeded. In loose 

 volcanic sand on the highest mountain peaks, Oregon and Washington to 

 California and Utah. 



C. glutinosa Benth. Bot. Reg. 1833. Slightly pubescent, and glandu- 

 lar above : stem loosely branching, erect or diffuse, 1-2 feet long : leaves 

 nearly simple, or cut or parted into lanceolate or narrowly oblong divisi- 

 ons: flowers loose or scattered: calyx obtuse or roumded at base, deeply 

 cleft; the lobes subulate: stamens moderately unequal in insertion : ovules 

 1 or 2 in each cell : capsule globular. In open woods, California and Ore- 

 gon to Washington. 



4 LINANTHUS Benth. Bot. Reg. xix, t. 1622. 



Erect and slender annuals with opposite leaves and small 

 flowers solitary and terminal or in the forks of the branches, or in 

 capitate leafy-bracted clusters. Tube of the calyx cylindraceous, 

 white-scarious except the ribs which are prolonged into acerose- 

 linear teeth, not enlarged in fruit but usually ruptured by the 

 maturing capsule. Corolla rotate, campanulate, funnelform, or 

 salverform. Stamens equally inserted on the tube of the corolla. 

 Seeds numerous or rarely few in the cells, developing mucilage 

 when wetted.
