BUCKWHEAT FAMILY 



421 



to 21/2 inches long ; panicle usually large, the heads large, terminal and lateral, 

 less commonly* in the forks. Central Coast Ranges, dry rocky hills. 



Locs. Berkeley and Oakland hills. This form differs from the Sierra Nevada plant at 

 middle altitudes in its stouter stems, larger and denser heads which are often lateral on the 

 branches of the panicle as well as terminal. It is a peculiarity of the flowers that they tend 

 to persist in age, whereas in Sierra Nevada specimens they quickly fall in drying. 



Var. grande Jepson n. comb. Tall (3 to 5 feet high) with a woody base; 

 leaves ovate-oblong, the margin undulate-revolute, white-lanate below, iy 2 

 to 3 inches long ; involucres 3 lines long ; calyx nearly or quite glabrous inside.

 AURICULATUM Tracy. E. auriculatum Benth. Trans. Linn. Soc. 17: 412 (1837), type from 

 California, Douglas; "petiolis basi saepius auriculato-dilatatis" says Bentham, but in DC. 

 Prodr. 14: 13 he says "petiolis longis basi saepius auriculato-dentatis", neither of which 

 phrases apply well to our plants referred to this variety, which should be described as petiolis 

 sublongis basi subamplexicaulibus. Var. GRANDE Jepson. E. grande Greene, Pitt. 1: 38 (1887),

44. E. elatum Dougl. Stems rigid and rush-like, rarely naked, 1 to 2y 2 

 feet high, sometimes inflated, bearing a trichotomous panicle, glabrous and 

 glaucous; leaves erect, ovate to ovate-lanceolate, 1 to 3 (or 5) inches long, on 

 petioles mostly as long; involucres in terminal clusters of 2 to 4, or solitary 

 in the forks, either sessile or shortly pedunculate, hairy-pubescent, 2 1 / 4 lines 

 long, 5-toothed, the teeth scarious-margined ; calyx white, 1 to 1% lines long, 

 its segments obovate, rounded at apex, with broad hairy-pubescent midvein.

 leaves ovate or deltoid-ovate, truncatish at base, white-woolly below, whitish- 

 arachnoid above, persistent on both faces, iy 2 to 2y 2 inches long, the petioles 

 as long and with a broad clasping base ; involucres externally glabrous, tubular 

 but a little widened upward, 2 lines long, solitary and racemose along the 

 slender branches of the dichotomous panicle; calyx yellowish, glabrous.
