402 POLEMONIACEAE (PHLOX FAMILv) 



those subtending the cymose cluster longer than the flowers: flowers cymulose- 

 glomerate and leaf y-bracted ; tube of the corolla hardly exceeding the aristulate- 

 mucronate caljoc-lobes: anthers in the throat, on very short filaments: ovules 

 2 in each cell. — Texas to Colorado and west to Nevada. 



17. Gilia pumila Nutt. 1. c. Stems 1-2 dm. high, loosely woolly, at least 

 when young, leafy: leaves narrowly linear, entire or most of them 2 to 

 4-parted into diverging linear lobes, mucronate: flowers cymulose-glomeJate 

 and leaf y-bracted: tube of the corolla slender, about twice the length of the 

 aristulate-tipped calyx-lobes: filaments slender, inserted in the sinuses, ex- 

 serted, shorter than the lobes of the corolla: ovules" about 6 in each cell. — 

 From western Nebraska and Texas to the Sierra Nevada. 



18. Gilia pungens (Torr.) Benth. in DC. Prodr. 9: 316. 1845. Stems 

 woody, tufted, branched, very leafy, 1-3 dm. high: leaves alternate except 

 the lowest, much fascicled in the axils, or rather 3-7-palmately parted with 

 acerose segments: flowers sessile and solitary in the upper leaf-axils: calyx 

 tubular, with subulate teeth, glandular-ciliate : corolla roseate, white or 

 yellowish, tubular: stamens unequally affixed, scarcely exserted: ovules 

 many (6-10 in each cell): capsule oblong, shorter than the calyx. — From 

 New Mexico to the Canadian provinces. 



ISa. Gilia pungens Hookeri. (Dougl.) Gray, Proc. Am. Acad. 8: 288. 1870.

 Throughout our range. 



19. Gilia Watsonii Gray, 1. c. 267. Roughish-puberulent and glandular, or 

 at length smoothish; slender branches 1-2 dm. high from the woody caudex: 

 leaves not much fascicled, widely spreading; the slender acerose divisions 

 10-15 mm. long, often shorter than the internodes: calyx-lobes barely half 

 the length of the tube: corolla nearly white with purplish throat; the tube and 

 lobes each about 12 mm. long:- anthers at the orifice: ovules 10 or more in each 

 cell. — Utah and probably in western Colorado and Wj'oming. 



20. Gilia caespitosa (Gray) A. Ncls. 1. c. 2o: 546. Densely caespitose, the 

 much-branched woody base hardly emergent from the soil; stems numerous 

 and very short, clothed with the persistent crowded leaves: leaves alternate, 

 palmately 3-parted (rarely 5-parted), densely fascicled, rigid, subulate- - 

 pungent, 5-7 mm. long, nearly glabrous or somewhat ciliate on the margins, 

 green as to the new leaves, the short stems gray with the persistent dead ones: 

 flowers numerous: calyx one half the length of the corolla-tube, the lobes 4 

 (rarely 5), acerose: corolla white to yellowish, salverform, the tube very slender 

 and but little dilated at the throat, about 12 mm. long; lobes 4, narrowly 

 obovate, about 4 mm. long: stamens 4; filaments short, anthers in the throat: 

 pistil less than half the length of the corolla-tube; styles 2 or rarely 3. — Dry 

 bluffs; western Nebraska to the interior desert areas of Wyoming; rare. 



21. Gilia Nuttallii Gray, 1. c. Cinereous-puberulent or the leaves glabrate, 

 more or less woody at base; stems or branches 1^ dm. high, terminated by a 

 dense leafy cluster of flowers: leaves 3-7-parted; the divisions narrowly linear, 

 mucronate: corolla white with yellow funnelform throat; the tube not longer 

 than the calyx: ovules a pair in each cell. G. floribunda Gray, 1. c. — Moun- 

 tains of Colorado and Utah to Arizona and theSierras of California. 



22. GiUa Harknessii Curran, Bull. Cal. Acad. 1: 12. 1884. Stem erect, 

 diffusely branched, 8-20 cm. high: leaves divided to the base into filiform 

 segments, 5-20 mm. long: flowers paniculate, on filiform pedicels 12-25 mm. 

 long: calyx minutely ^jubescent; the lanceolate lobes as long as the tube: corolla 

 white, 2^ mm. long; the tube but little longer than the calyx and about as 

 long as the lobes: capsule oval, exceeding the caljrx; seeds solitary in the cells, 

 smooth, turgid, oblong, about 2 mm. long.- — Western Wyoming to the Pacific 

 States. 



23. GiliapharnaceoidesBenth. Bot.Reg. 19:pl. 1622. 1S33. Stem slender, 

 with diffuse filiform branches, 1-2 dm. high: leaves palmately 2-5-parted into 

 acerose-pubescent segments, 4-12 mm. long: flowers paniculate, on filiform 

 pedicels: calyx campanulate, 4-5 mm. long; the triangular acute lobes not 

 as long as the tube: corolla almost rotate, the broad tube hardly as long as the
