298 HYDROPHYLLACEAE. 



4. P. distans Benth. Stems much branched, ascending, 3-5 dm. 

 high; herbage with scattered hispid hairs and close fine pubescence; 

 leaves pinnatcly 9-17-divided into Hnear-oblong 1-2-pinnatifid or 

 cleft divisions; spikes scattered, solitary or geminate; sepals un- 

 equal, narrowly obovate to spatulate; corolla 6-8 mm. long, rotate- 

 campanulate, usually blue, rarely paler, the lobes rounded; internal 

 appendages semiovate with free pointed tips; stamens little or not 

 at all exserted. 



Very common in the plains and foothills. March-May. 



5. P. tanacetifolia Benth. Much resembling the last, but usually 

 stouter, erect, sparsely branching or simple; leaves similar, larger 

 and less finely dissected; spikes terminating the branches, approxi- 

 mate, 6-9 cm. long; sepals linear, beset with rigid bristles, in fruit 

 little exceeding the oval capsule; corolla open-campanulate, 6-8 

 mm. long, lavender, the lobes blunt, not rounded; internal appendage 

 entirely adnate, the tip rounded. 



Slender specimens of this species were collected on the northern 

 slope of the Santa Monica Mountains, between Cahuenga Pass and 

 Encino, by the author in April, 1901; otherwise it is not known 

 within our limits. 



6. P. ciliata Benth. Branched from the base with rather simple 

 ascending branches, 2-4 dm. high, herbage scabrous, otherwise 

 glabrous; leaves pinnately divided, the divisions oblong, toothed or 

 incised; spikes rather short, becoming loose in fruit; pedicels short 

 or almost wanting; calyx-lobes lanceolate to broadly ovate, charta- 

 ceous, 7-10 mm. long in fruit, with thickened midrib and reticula- 

 tions, sparsely bristly-ciliate; corolla blue; stamens shorter or about 

 equaling the corolla; capsule ovate, mucronate, about half the length 

 of the calyx-lobes, which are arched over it; seeds oval, favose. 



Open grassy hills, not common. Hollywood; Capistrano. 



7. P. viscida (Benth.) Torr. Stem erect, mostly simple, 3-6 

 dm. high, very glandular above; leaves ovate or obscurely cordate, 

 doubly or incisely and irregularly dentate, 2.5-6 cm. long; calyx- 

 lobes linear or obscurely spatulate, obtuse, 7-8 mm. long; corolla 

 deep blue with purplish or whitish center, rotate-campanulate, 

 10-20 mm. broad; capsule ovate, abruptly cuspidate-pointed, 

 equaling the calyx. 



Frequent in all the mountains bordering coast valleys, espe- 

 cially common on fire-swept places in the chaparral belt. 

 March-May. 



7a. P. viscida albifiora (Nutt.) Gray. Flowers white, otherwise 

 as in the typical form. 



Same range as the last but less common. 



8. P. grandifiora (Benth.) Gray. Closely resembling the last, 

 but usually more robust and more viscid; leaves larger; calyx-lobes 

 linear, 8-10 mm. long; corolla rotate-campanulate, 2.5-4 cm. broad, 

 purplish or pale bluish; capsule equaling the calyx, the cuspidate 

 persistent and indurated, base of the style 2 mm. long. 



Same range as the last and growing in similar places. April- 

 May.
