248 POLEMONIACE^E. 



small, deep blue: stamens not exserted: seeds numerous, small, black. 

 A noxious wayside weed; Skunk weed, of the country people June Oct. 



11. X, atractyloides (Benth.), Hook. Am. Stout and low, with 

 short branches paniculately arranged: leaves ovate-lanceolate, rigidly 

 coriaceous, in age reticulate, the margins beset with straight spinose- 

 subulate teeth: segments of the calyx subulate, entire, erect-, only 

 moderately unequal: corolla narrowly funnelform, % inch long, deep 

 purple. From the lower Sacramento southward. Ill-scented like the 

 last, but less common. June Aug. 



4. (ilLIA , Ruiz & Pavon. All our species (except n. 6) annuals, with 

 leaves alternate, flaccid, not pungent, 1 3-pinnately dissected into 

 narrow segments. Flowers more or less clustered at the ends of the 

 few branches, the clusters not bracteate. Calyx-teeth equal, connivent 

 or recurved in fruit; tube in some (scarcely in our species) ruptured to 

 the base (through scarious sinuses) by the splitting of the capsule. 

 Corolla funnelform. Stamens inserted equally on its throat. Seeds 

 several in each cell of the capsule. 



1. G. capitata, Dougl. Slender, 1 2 ft. high: leaves dissected into 

 filiform lobes: fl. many, in dense capitate long-peduncled clusters: calyx, 

 nearly glabrous, infr. globose: corolla very small, light blue; tube scarcely 

 dilated at the throat; segments nearly linear: stamens inserted in the 

 sinuses of the corolla. Species of the higher parts of the Coast Range. 



2. G. achilleaefolia, Benth. Stoutish, pubescent, 13 ft. high, the 

 head-like flower-clusters larger and less compact: calyx more or less 

 woolly; the somewhat triangular teeth connivent over the growing ovary : 

 corolla broad-funnelform, deep or pale blue; lobes obovale or oblong; 

 throat abruptly and amply dilated. Common in sandy soil. May Aug. 



3. G. multicaulis, Benth. Slender, in age commonly diffuse, % 1% 

 ft. high: leaves twice cleft into narrowly linear lobes: fl. few and in less 

 dense clusters, on short peduncles: calyx-teeth recurved in fruit: corolla 

 nearly salverform, deep or pale blue, its lobes obovate: capsule ovoid. 

 Rocky hills and sandy plains; extremely variable. April June. 



4. G. tricolor, Benth. Slender, seldom a foot high, cymose-panicled : 

 leaves and calyx almost as in the last, but fl. much larger and ampler, 

 distinctly 3-colored: corolla %in. long; tube yellow; ample campanulate- 

 funnelform throat marked with deep violet-purple or darker; broad 

 rounded lobes white or lilac. Common from Napa and Solano counties 

 northward and southward, but chiefly in the interior. April, May. 



5. G. gilioides (Benth.), Greene. Loosely branching, % 2 ft. long, 

 viscid-pubescent: leaves simply cut into few narrowly oblong or lanceolate 

 divisions: fl. few in the cluster: corolla slender-salverforrn, deep blue- 

 purple: stamens hardly equally inserted: capsule globular: ovules and 

 seeds 1 or 2 in each cell. Higher parts of the Coast Range. May July.
