4, M. Californica Gray Mex. Bound. 173. M. levis (Benth.) | 
Curran, Bot. Sulph. 44, Proce. Cal. Acad. 2 1 235. Flowers _ 
1-3, less than 6” long, broadly funnel-form with a short tube, 
very delicate; involucre bell-shaped, not over 3” long, five-cleft _ 
with acute lobes, fruit broadly obovate, 14-24” long, obscurely 
10-grooved; leaves broadly ovate, 1’ or less long, on very short — 
petioles. This belongs to the Larrea Zone from southern Utah, — 
California and southward and runs up into the lower Juniper in — 
the Sierras. M. Bigelovii Gray Proc. A. A. 21 413 with very © 
viscid-villous pubescence, stems and rounded leaves flaccid, 
flowers pale and little longer than the involucre, is probably only — 
a form of this; it is found at Peach Springs, northern Arizona. 
M. tenuiloba Wats. Proc. A. A.17 375. Viscid-pubes- — 
cent; like M. Californica but leaves somewhat acuminate, with 
cordate base, and often halberd-shaped; involucre 3-5” long, cleft | 
below the middle and divisions narrowly lanceolate; petioles — 
slender, 6-9” long; stems white; seeds oblong, barely grooved, 2 
trifle wider above, 4” wide, 13” long. Probably only a form of 
this very variable species, but leaves remarkable. San Bernar-— 
dino Co., Cal., to Fairview near Williams, Arizona. Juniper to — 
Larrea Zone. 
7. ALLIONIA Leefl. (Oxybaphus Vahl.) 
Stamens usually 3; fruit several-ribbed or angled except in | 
A. oxybaphoides; involucres 5-lobed and 1-5 flowered, in 
fruit generally spreading out flat, especially after the fruit has , 
fallen, flowers bell-shaped, very delicate, translucent, with deli- 
cate ribs, white to purplish (except A. coccineus, which has — 
‘conspicuous, red, nearly tubular, long flowers), small; stigma 
capitate on a filiform style; plants tufted, tall and erect, often 
widely branched; A. hirsuta sometimes 1° and A. Bodini not
