290 POLEMONIACEAE. 



noid-tomentose, more or less glandular above; basal and lower 

 leaves simply pinnatifid, linear-lanceolate, 3-5 cm. long, with short 

 ovate or triangular and cuspidate-tipped lobes, these often enlarged 

 and toothed or lobed; the cauline few, becoming entire and subulate 

 above; paniculate cymes very loose; flowers mostly on elongated 

 almost capillary pedicels, about 1 cm. long, dilated-funnelform, 

 abruptly contracted below into a narrow tube, which equals or slightly 

 exceeds the calyx, its lobes rounded-obovate, purple, the throat 

 yellowish below; capsule obovoid. (G. latiflora exilis Gray.) 



Wilson's Peak under pines, and similar places throughout the 

 San Gabriel Mountains. 



8. G. grinnellii Brand. Loosely paniculate, branched above, 

 5-8 dm. high, hispid pube-scent below, glandular above; basal leaves 

 4-6 cm. long, bipinnately parted or divided; the upper becoming 

 simple, small and entire; branches loosely few-flowered; pedicels 

 shorter than the flowers; corolla 2.5-3 cm. long, lilac color with 

 purple tube, narrowly funnelform, tapering to the long slender tube; 

 capsule ovoid-oblong. 



Frequent in open pine forests in the San Gabriel. 



9. G. virgata Steud. Annual, white-floccose, becoming glabrate; 

 stems slender, either simple and virgate or with virgate branches 

 from the base and paniculately branched above, 1-3 dm. high; 

 leaves slender-filiform, the lower mainly entire and the upper rarely 

 more than 3-parted; corolla blue or lavender, its tube 8-12 mm. 

 long, surpassing the acerose calyx-lobes; anthers linear-sagittate, 

 2 mm. long. 



Frequent in the foothills and plains in the interior region, mostly 

 east of our limits. 



9a. G. virgata ftoribunda Gray. Branches few, terminated by 

 large, compact flower clusters; most of the leaves pinnately 3-7- 

 parted; corolla somewhat larger than in the type. 



On dry plains from Azusa eastward. 



10. G. densifolia Benth. Perennial, canescent-lanate when 

 young, becoming glabrate in age; stems rigid, branched from the 

 woody base, usually somewhat spreading, 1.5-3 dm. high; leaves 

 rigid, mostly pinnatifid or incisely laciniate into short subulate 

 spinulose lobes; flowers densely clustered, capitate-glomerate; corolla 

 violet-blue, its tube about 12 mm. long, 2-3 times the length of the 

 calyx; anthers sagittate. 



Occasional in open places, mostly on dry ridges, in the pine 

 belt of all the mountains. 



4. LEPTODACTYLON H. & A. 



More or less woody or shrubby, commonly tufted, very 

 leafy plants. Leaves commonly alternate, and much 

 fascicled in the axils, palmately 3-7-parted, acerose- 

 subulate, rigid and pungent. Flowers showy, solitary 

 and sessile or few in clusters at the summit of the branches
