Acaulescent, glabrous, with slender scape (15 to 30 em. high) bear 
ing 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 prominent scartous-margined yeiny 
bractlets more or less united; rays 2.5 to 7.5 em. long; pedicels hardly 
2mm. lone; fruit small, in nearly sessile clusters of 2 to 8, oblong, 8 
mm. long, about + mm. broad, the lateral ribs considerably thicker 
than the body, the dorsal and intermediates very slender filiform to 
obsolete, occasionally with minute calyx teeth; oil tubes none; the 
commissural ridge small or almost wanting. 
Type locality, “‘Carbondale [Mount Diablo region], California;” 
collected by JL AL Curran, May, 1886; type in Herb. Coulter, 
Only known from the type locality. 
Specimens evramined: 
Cauirornia: Type locality, Brandegee, April-June, 1889; same station, from 
Herb, Greene, April 6, 1894. 
6. Leptotaenia humilis C. & R., sp. nov. 
Low, acaulescent, glabrous throughout; leaves about 5 times ter- 
nate, ultimate segments elongated, linear, entire; peduncle | to 2 dm. 
long; rays very unequal, 2 to 5 cm. long; pedicels | to 7 mm. long: 
involucre none; bractlets of the involucel linear to lanceolate, acumi-

Type locality, plains near Chico, Butte County, Cal.: collected by 
Mrs. OC. CC. Bruce, no. 2661, May, 1897: type in Herb. Cal. Acad. 
Sci., fragment and photograph in U.S. Nat. Herb. 
Specimens examined: 
CaLirornta: Type specimens as cited under type locality; also Little Chico Creek, 
Mrs, Austin 257, in 1896, 
This species is nearest L. anomala, but certainly very distinct. 
7. Leptotaenia purpurea (Watson) C. & R. Rev. N. Am. Umbell. 52. 
1883. 
Ferula purpurea Watson, Proce. Am, Acad, 21: 4538. 1886. 
About 3 dm. high; leaves completely glabrous, very much dissected, 
the ultimate segments linear or filiform; umbel 8 to 20-rayed, with no 
involucre, and involucels of several linear acuminate bractlets: rays 
7.5 to LO em, long; flowers purple; fruit 18 to 241mm. lone, as long as 
the pedicels, 10 to 12 mm. broad, with a much more prominent corky 
margin and commissural ridge than in any other species; oil tubes 
prominent, 3 in the intervals of the distinet dorsal and intermediate 
ribs, 4 on the commissural side. 
Type locality, **on rocky hillsides near the lower Columbia River, 
in Klickitat County, Wash.,” colleeted by Suksdor7, no. 281, Mareh 
21, 1880; type in Herb. Gray. Associated with the type in the origi-
