thick; stamens not longer than the calyx: Probably escaped 
from cultivation in the Tropical Zone of Arizona. 
2. M. Wrightiana Gray Trans. N. Y. Acad. 14 28, generally 
referred to M. longiflora L. Viscid pubescent at least above; 
blade of leaves halberd-shaped, with an acuminate tip, 2-3’ long, 
prominently veined, lower petioles about as long as the blade; 
stems nodose, paniculately branched, tall and nearly erect; 
flowers sessile in the involucre; lobes of the involucre subulate 
from a broad base; calyx tube about 2-3’ long; stamens and style 
much exserted. Southern Arizona to Texas and southward. 
A2B. Flowers witha short and broad tube, barely as ie as 
the involucre, about 1-2’ long, mostly purple.

Bound 169, Stout and coarse with large leaves on short petioles; 
flowering peduncles short; involucre large, not deeply cleft, 
five lobed, with acute lobes; flowers usually six within the 
involucre, 14-2’ long, large, not delicate, the lobes nearly ro- 
tate, spreading, purple or purple-streaked, concave, base star- 
like by stiffer and triangular ribs which run to the sinuses 
and project as teeth; throat with a dark wine-purple ring, tube 
long-conical, ribs feather-veined; stamens and style declined 
below and upcurved at tip; style longer than the involucre; fruit 
nearely 4’ long, marked toward the base with ten oblique furrows, 
smooth. Tufted and decumbent plants. Th#s occurs in the 
Juniper Zone, sparingly, from Colorado i, > California and south- 
ward to central Arizona. 
Var. Froebelii (Behr) Proc. Cal. Acad. 1 69. var. pubescens 
Wats. Bot. Cal.2 2. Plants very pubescent throughout. This 
hardly deserves varietal rank. A form of it with upper part of 
plant very pubescent occurs in eastern Nevada, in the Juniper 
Zone. Variations also occur in Utah with the outside of calyx 
and upper part of plant short-pubescant and glutinous with 
minute hairs standing straight out from the plant.
