to ovate or roundish, undulate and irregularly revolute-margined. truneatish 

 or subeordate at base, dark green and glabrate above, white with a dense felt 

 beneath, 2 to 6 lines long, shortly petioled; peduncles short, simple or iimbel- 

 lately 2 or 3-forked, bearing terminal or raeemosely scattered heads of in- 

 volucres, the heads few, compact, also sessile in forks when the inflorescence 

 is umbellate ; involucres 2 lines long, glabrate outside, densely woolly on in- 

 side at throat ; calyx white, glabrous, IVo to 2 lines long, its segments obovate, 

 the outer obtuse, the inner slightly broader and retuse; filaments a little hairy 

 at base.

41. E. fasciculatum Benth. PYat-top. "Wild Buckwheat." AVoody at 

 base, 2 to 3 feet high, with shreddy bark; branches very leafy, ending in a 

 mostly short (1 to 3 inches) peduncle bearing the inflorescence; involucres 

 in capitate clusters or heads ; heads terminal on the unequal rays or sessile 

 in the forks of a simple or compound umbel, or the umbel reduced and capi- 

 tate; rays 1 to 4 inches long; bracts linear; leaves oblong, linear or oblance- 

 olate, revolute margined, 4 to 8 lines long, drawn down to a narrow base, 

 densely white-wooll.y below, usually green and glabrate above; involucres 

 2 lines long, with short acute teeth; calyx white, glabrous, II/4 to 1% lines 

 long, the outer segments elliptic, the inner obovate and narrower, all rounded 

 at apex ; filaments glabrous or nearly so. 



Abundant on mesas and mountain slopes from Monterey Co. to Southern 

 California. It is generally known as "Wild Buckwheat" and is the third most 

 valued native bee-plant after White Sage and Black Sage. The typical form 

 described above, with glabrous flowers, is confined to the sea-coast from Santa 

 Barbara to San Diego. The two dominant mesa forms are the following 

 varieties. 



Var. foliolosum Stokes. Peduncles long (4 to 10 inches) ; leaves more 

 strongly revolute-linear, green but pubescent above, tomentose beneath; 

 calyx slightly hairy outside. — Chaparral slopes, the abundant form: Santa 

 Barbara to San Diego and east to San Bernardino and Temescal. 



Var. polifoliiun T. & G. Peduncles long; foliage gray, the leaves commonly 

 less revolute, hoary above, tomentose below ; calyx often conspicuously 

 hairy outside, especially towards the base. — Desert slopes of the mountains 

 in the Colorado and Mohave deserts west to Palomar; north to Bakersfield 

 and Inyo Co., east into Nevada.

42. E. latifolium Smith. Flowering stems from a densely leafy caudex, 

 stout, tomeutulose, naked, Y2 to 2 feet high, 2 to 4-forked above, the forks 

 simple or again forked ; involucres in capitate clusters, terminal and sessile in 

 the forks, or the whole inflorescence often reduced to a single large head 

 or with one proliferous branch from under the first head; leaves ovate to 

 oblong, obtuse or acute, at base rounded or cordate, rarely cuneate, often
