6. L. Californica Nutt. Ton-. & Gray, FI. i. 630. About 
*2 feet high, with 1 or 2 stem leaves: leaves ternate and pinnate or 
twice ternate; leaflets cuneate-ohovate, .1 to 2 inches long, usually 
41-lobed, coarsely toothed above: umbel 15 to 20-rayed, with in- 
volucre of 1 or 2 narrow bracts or none, and no involucels; rays 2 
to 4 inches long; pedicels 2 to 4 lines long: fruit 5 to 7 lines long, 
3 to 4 lines broad, with a thinner margin than in any other species; 
dorsal and intermediate ribs indistinct: oil-tnbes 3 or 4 in the in- 
tervals, 6 on the commissural side. (Fig, 38.) — Fe^'ula Cali- 
fornica Gray, Proc. Am. Acad. vii. 348. 
From Kern county, California {Parish 1941), through the state to 
Oregon {Howell, Henderson). FI. May. 
/ 7. L. anomala. Acaulescent, glabrous, with slender scape 
(6 to 12 inches high) bearing an unequally 3 to 6-rayed umbel: 
leaves slender petioled, pinnate with few distant very narrowly 
linear divisions: umbel with no involucre, and involucels of promi- 
nent scarious-margined veiny bractlets more or less united; rays 
1 to 3 inches long; pedicels hardly a line long: fruit small, oblong, 
in nearly sessile clusters of 2 to 8, 4 lines long, about 2 lines broad, 
the lateral ribs considerably thicker than the body, the dorsal and 
intermediates verv slender filiform to obsolete, occasionally with 
minute calyx-teeth: oil-tubes none: the commissural ridge small or. 
almost wanting. (Fig. 39.) 
Carbondale, California, May, 1886 {M, K. Curran). 
This curious species is really anomalous, combining in a certain way 
the characters of several genera. Its fruit characters are prominently 
those of Leptotcenia, its whole general habit approaches certain species of 
Peucedanum, and its occasional calyx-teeth look towards Polytmnia. 
16. PEUCEDANUM Linn. Gen, n. 339. Short caules- 
cent or acaulescent dry ground perennials, with fusiform or tuber- 
ous roots, ternate or pinnate to dissected leaves, no involucre, in- 
volucels mostly present, and yellow (sometimes white) flowers. 
Our largest and by far the most diffleult genus, with ill-defined boun- 
daries in some directions. Our North American species, all western, form 
a group different in some respects from foreign representatives of the 
genus, but not distinct enough to justify separation, without a critical 
study of the immense display of foreign forms.
