314 Polemoniaceae 



throat. Capsule at length distending and rupturing the 

 calyx. Seeds several in each cell, becoming mucilaginous 

 when wetted. 



* Leaves mostly 1-3-pinnately dissected, not pungent; flowers usually 

 in capitate bractless clusters. 



1. G-. multicaulis Benth. Branching from the base, 4-6 dm. 

 high, nearly or quite glabrous ; leaves pinnately parted into 5-9 

 linear and entire or toothed lobes ; flowers few in the clusters, 

 subsessile or on more elongated pedicels; calyx-teeth erect or 

 recurved in fruit, the hyaline margin very narrow; corolla deep 

 or rather pale purple, its proper tube shorter than the obovate 

 lobes; stamens included ; capsule ovoid. 



Frequent on the plains and foothills in our coast region. 



2. G-. achilleaefolia Benth. Stems 3-5 dm. high, glandular- 

 puberulent throughout ; leaves mostly bipinnately dissected into 

 linear, somewhat recurved segments; branches few, naked, bear- 

 ing a dense cluster of usually deep blue flowers ; calyx glandular- 

 pilose, mainly hyaline, its lobes incurved in fruit; corolla-tube 

 cylindric; throat very short and broad; lobes oblong, scarcely 

 spreading; stamens exserted. 



Common on dry plains and foothills throughout our range. 



3. GK abrotanifolia Nutt. Herbage glabrous throughout or 

 very sparsely pilose on the petioles and calyx; stems 3-6 dm. 

 high, with a few ascending branches or simple naked above, bear- 

 ing a terminal dense cluster of large pale blue flowers; leaves 

 large, thin, 3-pinnately dissected, the segments very narrowly 

 linear ; calyx glabrous or sparsely pilose, mainly hyaline, recurved 

 or spreading in fruit ; corolla with f unnelform throat and obovate 

 lobes ; stamens included or scarcely exserted. 



Frequent in open places in the chaparral belt of all our mountains. This 

 and the next have been called O. capitata Dougl., but that is a small-flowered 

 species of Oregon. 



4. G. staminea Greene. Closely resembling the last in habit ; 

 stems and leaves sparsely pilose ; calyx densely arachnoid-villous,. 

 mainly hyaline, its lobes recurved ; stamens well exserted, nearly 

 white. 



This species is common in the San Joaquin Valley and may occur within 

 our limits.
