 Appendages 10, vertical. 



Styles cleft to the middle; seeds not 

 transversely corrugated. 

 Plants erect; flowers subsessile, 



spicate. 12. P. brachyloba. 



Plants decumbent ; flowers loosely 

 racemose.

Leaves, at least the upper- 

 most, entire or with a few

1. P. magellanica (Lam.) Coville. Hispid and the foliage 

 strigose, more or less canescent, 2-5 dm. high, from a perennial or 

 biennial root; leaves lanceolate to ovate, acute, pinnately and 

 obliquely straight-veined; the lower tapering into a petiole, and 

 commonly some of them with 1-2 pairs of smaller lateral leaflets; 

 inflorescence hispid, the dense spikes thyrsoid-congested; corolla 

 whitish or bluish, moderately 5-lobed, longer than the oblong- 

 lanceolate or linear calyx-lobes; filaments much exserted, sparingly 

 bearded. 



Frequent on dry hillsides in the valleys and mountains. 



2. P. ramosissima suffnitescens Parry. Perennial; stems much 

 branched from the base, decumbent or ascending, lignescent at 

 base, often 2 cm. or more in diameter; herbage hispid pubescent 

 and more or less glandular above; leaves 5-9-divided or -parted, 

 with oblong or narrower pinnatifid-incised divisions; spikes glomer- 

 ate, short and dense; flowers subsessile, ascending in fruit ;_ sepals 

 ovate to obovate-oblanceolate; corolla bluish or dirty white; its 

 lobes spreading or somewhat reflexed, short, scarcely as long as the 

 diameter of the throat; stamens and style moderately exserted; 

 capsule globose-ovoid; seeds deeply pitted, oval. 



Common in the chaparral belt and on sand-dunes along the 

 seashore. Specimens from Playa del Rey show 5 annular rings near the 

 base. 



3. P. hispida Gray. Annual (as are all the following species), 

 5 dm. high or less, diffusely branched, setose-hispid with long slender 

 white bristles; leaves with rather few, coarse divisions the upper- 

 most sometimes merely laciniate-incised; spikes soon loose and 

 loosely paniculate; flowers on short slender horizontal pedicels; 

 corolla very pale blue, rotate or campanulate; lobes rounded at 

 apex; calyx-lobes narrowly linear with attenuate base nearly equal- 

 ing the corolla, in fruit 8-12 mm. long and almost 4 times the length 

 of the globose capsule; seeds short-oval, roughish-scrobiculate. 



Very common in the chaparral belt in open grassy places. April- 

 June.
