 oblong, rounded or cordate at base, densely white-woolly beneath, lanate or glabrate above. 2.5-^ 

 cm long the margins plane or somewhat crisped ; flowering stems leafless, floccose-tomentose, 

 stout, 2-6 dm. high, simple or 2-4-forked, the forks simple or again forked ; involucres congested

 California. Type locality: "Plains of the Multoonah [Willamette Valley]," Oregon. Douglas. June-Nov. 



Eriogonum nudum var. deductum (Greene) Jepson, Fl. Calif. 420. 1914. (£. deductum Greene, 

 Pittonia 5- 71. 1902.) Smaller plant, 2-4 dm. high, with slender trichotomous branches, or an extreme torm 

 (£ scapigerum Eastw.) reduced to a single simple stem bearing a solitary head; flowers white tinged with rose, 

 glabrous without. This variety inhabits the Boreal Zones of the Sierra Nevada, California. 



Eriogonum nudum var. publiflorum Benth. in DC. Prod. 14: 13. 1856. (£. nudum var. oblongifolium 

 S Wats7£. sulphureum Greene, E. saxicola Heller.) Flowers usually yellow, but sometimes white, villous- 

 pubescent without, at least toward the base. Interior and eastern California from Modoc and Siskiyou Counties 

 to the Mojave Desert. 



Eriogonum nudum var. pauciflorum S. Wats. Proc. Amer. Acad. 12: 264. _ 1877. Branches usually many, 

 dichotomous, and rather virgate; involucres mostly solitary or rarely in pairs in the axils and at the ends ot 

 the branchlets; calyx white, glabrous. Southern Sierra Nevada and South Coast Ranges California, to northern 

 Lower California. Merges with variety pubiflorum, and one of these intermediate forms is h. grammeum

 Eriogonum nudum var. grande Jepson, Fl. Calif. 421. 1914. 



Woody at base, the leafy branches 1-3 dm. high, terminated by stout glabrous peduncles, 

 5-15 dm. high. Leaves long-ovate to ovate-oblong, 2-12 cm. long, obtuse to rounded at apex, 

 more or less cordate at base, strongly undulate-crisped on the margin, densely white-velvety be- 

 neath, green with scattering floccose tomentum above; inflorescence dichotomously ortrichoto- 

 mously branched; involucres 2-3 or often solitary at the nodes, prismatic, 5-6 mm. high, shal- 

 lowly 5-toothed, glabrous without, pilose-tomentose on the throat within; calyx 2.5-3 mm. long, 

 glabrous, white or tinged with rose, the lobes narrowly obovate, rounded at apex; filaments 

 pubescent.
