A NEW WEST AMERICAN PEUCEDANUM. 



By Willis L. Jepson. 



■J Peucedanum erosum. Acaulescent, glabrous; peduncle stout- 

 ish, 1|— 2 feet high ; leaves, exclusive of the petiole, about 6 or 7 

 inches long, pinnately dissected into linear or oblong segments 3-4 or 

 5 lines long; involucre none; bractlets of the involucel oblong- 

 linear, 2-3^ lines long, 3-dentate (sometimes 4-dentate) ; rays very 

 unequal, lf-4^ inches long; pedicels 1-1| lines long; flowers 

 unknown; fruit large, ellii^tic-oblong, 6 lines long, the wing equal- 

 ing or exceeding the body in breadth, the margin all around erose 

 or denticulate; oil tubes none on the face or back; ribs distinct, 

 filiform. 



Described from abundant fruiting material collected by Miss 

 Alice Eastwood, at Exeter, Tulare County, on the east side of the 

 San Joaquin Valley, May 26, 1895. This new species is plainly 

 most nearly related to P. cartdfolium, but has longer and much 

 more unequal rays, distinct ribs, and broader wings, which are not 

 entire.

LuPiNUS CONFERTUS, Kell. This lupine covers many acres in 

 Bear -Valley. It flowers very abundantly and each dense spike 

 must have an existence of two or three months. Its heavy fragrance 

 advertises it from afar. The flowers are mainly violet with sugges- 

 tions of crimson, as they grow older, and are from five to six lines 

 C*o long. The structure of lupines with reference to pollination is 

 C7J perhaps too familiar to botanists to need detailed description here. 

 In this species, as in all the others that I know, the pollen of the 

 f^ five longer stamens is discharged into the keel in the bud, and is
