Leaves, at least the lower, incisely lobed or parted. 



Racemes scorpioid, the flowers subsessile ; corolla nearly 2 times as long as calyx ; style 



glabrous; inner South Coast Range 10. P. breweri. 



Racemes not scorpioid or scarcely; corolla little exceeding calyx; style slightly hairy at 



base; San Gabriel Mts. and Sierra Nevada in Kern Co 11. P. lobata. 



Leaves entire or essentially so (or at least most of the leaves entire). 

 Corolla deciduous. 



Racemes loose, flesuous, the axis very slender, the capsules remote; flowers % to 1% 



lines long, borne on spreading pedicels; Sierra Nevada 12. P. eisenii. 



Racemes dense or moderately dense, not flexuous; flowers 1% to 2% lines long, borne 

 on ascending pedicels. 

 Stems hirsute; leaves thin, pallid; style cleft nearly 1^; Sierra Nevada, e. 



slope 13. P. humilis. 



Stems glandular-hirsute ; leaves thick, dark green ; style cleft more than V4 ; 



Sierra Nevada, w. slope 14. P. dociana. 



Corolla long-persistent, 2 times as long as calyx or nearly, its scales very long and narrow ; 



flowers crowded, divaricately spreading; Nevada and Placer Cos 15. P. marcescens. 



Leaves opposite (at least the lower ones) ; racemes loosely flowered, not scorpioid or scarcely 



so ; stamens included ; stem slender, usually simple below and oppositely branched above. 



Stem glabrous and glaucous below the branches; ovules 1 or 2 to each placenta; Sierra 



Nevada 16. P. racemosa. 



Stem puberulent; ovules 2 to 5 to each placenta; North Coast Ranges 17. P. pringlei. 



** Leaves cleft, parted or divided, the lobes or divisions always in some degree crenate or toothed. 



Leaves with many to numerous leaflets or divided into numerous segments or discrete divisions. 



Divisions of leaves mostly rather small (1 to 3 lines wide, rarely % or 1 inch wide), always 



sessile (except in P. umbrosa), commonly rather delicate with numerous teeth, lobes 



or scallops, the whole often more or less fern-like in appearance; pedicels Vi to 1 line 



long (except in P. cryptantha), puberulent or thinly bristly, sometimes glandular. 



Calyx with 1 to 5 of its lobes toothed, cleft or divided, 1 to 4 of the lobes often entire. 



Calyx-lobes pinnately divided into spatulate divisions; racemes crowded in dense 



clusters; capsule regularly dehiscent; San Clemente Isl 18. P. fiorihunda. 



Calyx-lobes dimorphic, 3 narrow and entire, 2 conspicuously expanded and leaf -like, 

 toothed or cleft, or one of the two entire ; racemes in corymbose panicles ; 



capsule membranous, not regularly dehiscent; Sierra Nevada foothills 



19. P. platyloba. 

 Calyx-lobes all entire, all alike or essentially alike, at most merely unequal. 



Calyx-lobes narrowly linear, lanceolate, oblanceolate or oblong, not becoming char- 

 taceous. 

 Hairs of ovary and capsule soft, aU essentially alike; fruiting pedicels rather 

 firm. 

 Racemes (especially at maturity) ascending or erect in an umbel-like clus- 

 ter above the foliage, very dense; corolla with erect or ascending 

 lobes; stamens long-exserted ; fruiting capsules erect; widely dis- 

 tributed, both cismontane and transmontane....20. P. tanacetifolia.
