POLEMONIACEAE. 289 



narrowly oblong or lanceolate divisions, or rarely all so divided, or 

 the upper palmately divided into 3-5 obovate or lanceolate divisions; 

 corolla 8-12 mm. long, salver-shaped, blue-purple; stamens unequally 

 inserted; capsule globose; seeds 1-2 in each cell. {Collomia gilioides 

 Benth.) 



Frequent in shady places in the chaparral belt throughout our 

 range. 



2. G. multicaulis Benth. Branching from the base, 4-6 dm. 

 high, nearly or quite glabrous; leaves pinnately parted into 5-9 

 linear and entire or toothed lobes; flowers few in the clusters, sub- 

 sessile or on more elongated pedicels; calyx-teeth erect or recurved 

 in fruit, the hyaline margin very narrow; corolla deep or rather 

 pale purple, its proper tube shorter than the obovate lobes; stamens 

 included; capsule ovoid. 



Frequent on the plains and foothills in our coast region. 



3. G. achillesefolia Benth. Stems 3-5 dm. high, glandular- 

 puberulent throughout; leaves mostly bipinnately dissected into 

 linear, somewhat recurved segments; branches few, naked, bearing 

 a dense cluster of usually deep blue flowers; calyx glandular-pilose, 

 mainly hyaline, its lobes incurved in fruit; corolla-tube cylindric; 

 throat very short and broad; lobes oblong, scarcely spreading; 

 stamens exserted. 



Common on dry plains and foothills throughout our range. 



4. G. abrotanifolia Nutt. Herbage glabrous throughout or very 

 sparsely pilose on the petioles and calyx; stems 3-6 dm. high, with 

 a few ascending branches or simple naked above, bearing a terminal 

 dense cluster of large pale blue flowers; leaves large, thin, 3-pin- 

 nately dissected, the segments very narrowly linear; calyx glabrous 

 or sparsely pilose, mainly hyaline, recurved or spreading in fruit; 

 corolla with funnelform throat and obovate lobes; stamens included 

 or scarcely exserted. 



Frequent in open places in the chaparral belt of all our moun- 

 tains. This and the next have been called G. capitata Dougl., but 

 that is a small-flowered species of Oregon. 



5. G. staminea Greene. Closely resembling the last in habit; 

 stems and leaves sparsely pilose; calyx densely arachnoid-villous, 

 mainly hyaline, its lobes recurved; stamens well exserted, nearly 

 white. 



This species is common in the San Joaquin Valley and may occur 

 within our limits. 



6. G. oreophila Greene, n. sp. Stems simple or branching from 

 the base, glandular-pilose above, 18-36 cm. high; lower leaves 

 pinnate, the divisions slender with a few lobes, the upper pinnately- 

 parted or pinnatifid; flowers loosely panicled; calyx 4 mm. long; 

 corolla violet, 6 mm. long, narrowly funnelform, the tube scarcely 

 equaling the calyx. (G. inconspicua, subsp. sinuata, var. oreophila 

 Brand.) 



Frequent in the chaparral belt of all the hills and mountains. 



7. G. exilis (Gray) n. sp. Diffusely paniculate-branched above, 

 3-4 dm. high, glabrous below or the young parts somewhat arach-
