scorpioid spikes or racemes. Calyx deeply 5-parted, 

 commonly more or less accrescent, unappendaged. Co-

 funnelform, deciduous, the tube commonly with internal 

 lamellate projections or appendages. Stamens inserted 

 on the base of the corolla-tube. Style 2-cleft. Capsule 

 1-celled, 2-valved, the thin septa-like placentae adherent. 



* Ovules 4 ; corolla-tube with 10 laminate appendages in pairs at 

 the base of the stamens. 



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 leaf- 

 lets ; 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 suffrutescens Parry. Perennial; stems 

 much branched from the base, decumbent or ascending, lignes- 

 cent 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 glomerate, 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 Port Ballona show 5 annular rings near base.

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

 der white bristles; leaves with rather few, coarse divisions, the 

 uppermost sometimes merely laciniate-incised ; spikes soon loose 

 and loosely paniculate ; flowers on short slender horizontal pedi-
