4. E. cinereum Benth. Shrubby, 8-15 dm. high, in dense clumps, 

 hoary-tomentose throughout; leaves orbicular to oblong, 12-18 mm. 

 long, on very short petioles, obtuse, undulate, strongly nerved; 

 peduncles elongated, sparingly dichotomously branched, bearing 

 few rather loose heads; bracts short; involucres 4 mm. long; perianth 

 very villous, rose-colored, 2-3 mm. long. 



Bluffs along the seashore at Santa Monica and San Pedro. 



5. E. parvifolium Smith. Shrubby, about 3 m. high, more or 

 less white-tomentose throughout; leaves broadly ovate to oblong, 

 8-18 mm. long, acute, abruptly narrowed at base to the very short 

 petiole, revolute and undulate on the margins, becoming glabrate 

 above; lower bracts conspicuous, the upper smaller; involucres 

 tomentose, about 3 mm. long; perianth rose-colored, glabrous, about 

 3 mm. long. 



Common on the sand-dunes along the seashore. 



6. E. fasciculatum Benth. (Wild Buckwheat.) Shrubby, 5 

 dm. high or more, more or less tomentose; leaves narrowly oblance- 

 olate, revolute, tomentose beneath, glabrate above, 6-18 mm. long, 

 much fascicled ; peduncles short or elongated, bearing a short cymosely 

 divided umbel; bracts rather conspicuous; involucres about 4 mm, 

 high, glabrate; flowers rose-colored or whitish, glabrous. 



The typical form is maritime, and more abundant about San 

 Diego. 



6a. E. fasciculatum foliolosum (Nutt.) Stokes. Leaves nearly 

 glabrous on the upper surface; perianth villous without. 



The common form on the mesas and foothills of the coastal 

 slope. 



6b. E. fasciculatum polifolium (Benth.) Torr. & Gray. Leaves 

 hoary tomentose above; perianth densely villous; cymes mostly 

 capitate. 



The common form on the desert slopes, sometimes growing in 

 the drier parts of the coastal region. 



7. E. kemiedeyi Porter. Woody caudex much branched, forming 

 a dense mat; densely clothed with obovateto oblong revolute v/hite- 

 tomentose leaves, about 6-12 mm. long; peduncles wiry, 5-20 cm. 

 long, more or less tomentose; involucres in a terminal capitate 

 cluster, turbinate-campanulate, nerved and strongly angled, deeply 

 triangular-toothed, 3-4 mm. long; perianth white or rose-colored, 

 glabrous, 2-3 mm. long. 



Coniferous forests of the southern Sierra Nevada to the San 

 Bernardino Mountains; Mt. Waterman, F. Grinnell. 



8. E. saxatile Wats. Caudex densely leafy, sparingly branched; 

 leaves rounded or obovate, obtuse, 12-16 mm. broad, cuneate at 

 base, densely tomentose on both sides; petioles short and thick; 

 branches of the cymose panicle 1-4 dm. long, spreading; bracts 

 subfoliaceous, triangular; involucres 3-4 mm. long, teeth acute; 

 perianth rose color, 2-3 mm. long, the lobes appressed to the nearly 

 glabrous achene, this abruptly narrowed at base. ( E. hloomeri Parish.) 



Frequent in the coniferous forests of the San Gabriel and San 

 Bernardino Mountains.
