puberulent without near the summit, limb 8-10 mm. broad; capsule 5-8 mm. high, 4-valved; 

 seeds reddish brown, punctate-reticulate, shining. 



Sandy washes and hillsides, Sonoran Zones; Santa Barbara County to the Colorado Desert and southern 

 Lower California. Type locality: ChoUas Valley, near San Diego, California. Feb.-June. 



6. Nicotiana Bigelovii (Torr.) S. Wats. Indian Tobacco. Fig. 4516. 



Nicotiana plumbaginifolia var. Bigelovii Torr. Pacif. R. Rep. 4: 127. 1857. 

 Nicotiana Bigelovii S. Wats. Bot. King Expl. 276. pi. 27. figs. 3-4. 1871. 



Ascendingly branched annual 3-15 dm. tall with glandular-pubescent, ill-smelling herbage. 

 Leaves sessile or the lower petiolate, ovate-oblong to narrowly lanceolate, 5-20 cm. long, often 

 acute at both ends; flowers distributed in open racemes along branches; calyx 1.5-2.2 cm. 

 long, the narrowly lanceolate teeth unequal, the longer ones about equaling the tube; corolla 

 4-7 cm. long, the limb 3-5 cm. broad, white, faintly tinged with green; stamens unequally 

 inserted in upper part of throat; capsule ovoid, about 1.5 cm. long, exceeded by calyx lobes. 



Along streams, on foothills and valley floors, Upper Sonoran and lower edge of Transition Zones; southern 

 Oregon to southern California where it grades into the variety. Type locality: Knights Ferry, Stanislaus County, 

 California. May-Oct. 



Nicotiana Bigelovii var. Wallacei A. Gray, Syn. Fl. N. Amer. 2^: 243. 1878. Corolla-limb 2-3 cm; broad; 

 capsule nearly equaling to slightly surpassing the calyx-lobes at maturity. Vicinity of Santa Barbara southward 

 into San Diego County. Type locality: Los Angeles. April-Oct. 



Nicotiana quadriv41vis Pursh (Fl. Amer. Sept. 1: 141. 1814), described from specimens cultivated by 

 tribes along the Missouri River, has a subglobose, 4-celled capsule, and Nicotiana multiv41vis Lindl. (Bot. Reg. 

 13: pi. 1057. 1827), described from garden plants grown from seeds collected by Douglas along the Columbia, 

 has a large, globose capsule with several cells. They are thought to be strains of N. Bigelovii that arose in the 

 fields of tobacco cultivated by the northwestern Indians, and are sporadically distributed throughout that area.
