454 POLEMONIACEAE collomia 



LINANTHUS 



panulate; the lobes attenuate from a broad base to a slender awn: corolla 

 purple, with filiform tube 4-6 lines long and small oblong lobes : capsule 

 obovate, with atteriuate base, 3-lobed. On open hillsides in mountains, 

 Brit. Columbia to California. 



C. heterophylla Hook. Bot. Mag. 2895. Gilia Sessei Don. Diffusely 

 branched from the base, 3rl6 inches high, soft pubescent throughout: 

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

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

 the flower-clusters : calyx' acute at base, cleft barely to the middle, the 

 lobes ovate-lanceolate, acuminate : corolla light purple to pink, slender, 

 .5-6 lines long, 2-3 times as long as the calyx : stamens very unequally 

 inserted : ovules 1-3 in each cell. Common in open woods, Brit. Columbia 

 to California 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, funnelform; the narrowly oblong-obovate ob- 

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

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



C. debilis^ Greene Pitt, i, 127. Gilia 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 

 cleft limb, light purple to blue : capsule a line long ; the cells 1-seeded. 

 In loose volcanic sand on the highest mountain peaks, Oregon and Wash- 

 ington 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 divi- 

 sions : flowers loose or scattered : calyx obtuse or rounded at base, deeply 

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

 1 or 3 in each cell: capsule globular. In open woods, California and 

 Oregon 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 mitcilage 

 when wetted.
