10 mm. long; flowers white or pinkish; fruit broadly oblong, 3 to 4 
mm. long, with sharp filiform ribs; stylopodium low, broad conical;

Type locality, ** rocky hills along the coast of California from Men- 
docino County to San Francisco,” collected by Bolander; type in 
Herb, Gray. 
In the coast: region from San Francisco, Cal., to western Oregon. 
Specimens examined:

Pimpinella apiodora nudicaulis Gray, Proc. Am. Acad. 8: 385, 1872, is to be referred 
to Ligusticum, but we have not been able to refer the material definitely to any 
described species. The type is a small flowering specimen now in Herb. Gray, and 
was collected by Hall (no, 206) in Oregon in 1871. 
6. Ligusticum apiifolium (Nutt.) Gray, Proc. Am. Acad. 7: 347, 1868. 
Cynapium apiifolium Nutt. in Torr. Gray Fl. 1: 641. 1840. 
Glabrous except the puberulent inflorescence and scabrous leaf 
margins; stems sometimes tall (9 to 12 dm.), with 1 to 3 small leaves; 
leaves twice or thrice ternate then pinnate; segments usually distinct, 
ovate, deeply cleft into linear usually entire and acute lobes scarcely 
paler ‘beneath: umbel many-rayed, with involucels of linear bractlets; 
rays 5 to10 em. long; pedicels 6 to LO mm. long; fruit broadly oblong, 
4mm. long, sharply ribbed; stylopodium low conical; oil tubes 3 to 
5 in the intervals, 4 to 8 on the commissural side. 
Type locality, ‘* plains of Oregon, near the confluence of the Wah- 
lamet;” collected by Vuttal/, June-July; type in Herb. Philad. Acad., 
fragments of type in Herb. Gray. 
In the lower Columbia River region of Oregon and Washington. 
Specimens examined: 
OreGoN: Type specimens as cited under type locality; Oregon City, Kellogg & 
Harford 314, July, 1869; Hall 207, in 1871; Sauvies Island, Multnomah 
County, Howell; Portland, Henderson, in 1882. 
WasnHrinaton: Near Montesano, Chehalis County, Henderson 2578, June 25, 1892;

An examination of the type specimens, and of gi vod material from the type local- 
ity, has enabled us to come to an understanding of this species. In the Gray Her- 
barium there is also a sheet of Nuttall’s Cynapium nudicaulis, which was included in 
L. apiifolium. The specimen is only in flower, but the different foliage suggests a 
distinct species. 
7. Ligusticum canbyi C. & R. Rey. N. Am. Umbell. 86, 1888, 
Stem about 6 dm. high, with alternate peduncles, leafy at base, with 
a small cauline leaf or two, and glabrous inflorescence; leaves large,
