prickles. Carpels without ribs : vittse numerous. Carpophore indistinct. 

 Seeds semiglobose. — Perennial herbs. Radical leaves with long petioles, 

 palmately lobed ; the lobes cuneate, incised and toothed towards the apex. 

 Stem naked or nearly so. Umbel with few rays. Umbellets with numerous 

 rays ; the flowers polygamous. Leaflets of the involucre few and often

 incisely and mucronately serrate ; middle one distinct to the base ; the lateral

Woods and thickets, Canada! and Newfoundland! to South Carolina; 

 and west to Arkansas ! Oregon, Douglas. June-July. — Stem about 2 feet 

 high, dichotomously branched at the summit. Middle segment of the leaves 

 petiolulate. Unibel somewhat compound and proliferous. Flowers white 

 or .rarely yellowish : fertile ones nearly sessile, on pedicels 1-2 lines long. 

 Calyx-tube echinate on every part. 



2. S. Menziesii (Hook. & Arn.) : leaves cordate, deeply 3-parted ; the 

 segments obovate-cuneate, variously lobed and incisely serrate ; serratures 

 mucronate and terminating in short hairs; umbels somewhat compound; 

 sterile flowers subsessile. — Hook. S^- Arn. ! hot. Beechey, j)- 142, iif suppl. p.

Borders of woods, (fee. Oregon, Dr. Scouler I Nuttall! California, Menzies, 

 Douglas. — Root long and somewhat fusiform. Stem stout, branching above. 

 Leaves 2-2i inches in diameter : segments usually dilated and rounded, but 

 sometimes rather acute. Flowers yellow. — Very nearly allied to S. Liber- 

 ia, and scarcely distinguishable except by its nearly sessile sterile flowers. 

 The Oregon plant differs from tlie Californian (on which the species was 

 founded) in the leaves being more obtuse, with shorter hairs at the point of 

 the serratures ; but in other respects we can discover no essential difference. 

 Mr. Nuttall, however, considers the Oregon plant as a distinct species, which 

 he calls S. obtusa. 



3. <S. laciniata (Hook. & Arn.) : stem branching from near the base » 

 leaves deeply 2-parted, with a cordate outline ; segments laciniately pinnati- 

 fid, narrow, setosely acuminate ; umbels compound ; involucre and involu- 

 cels bipinnatifidly laciniate. — Hook. Sy Arn. ! hot. Beechey, sujypl. p. 347. 



California, Douglas ! — Stem divided into several spreading branches. 

 Radical leaves on rather long petioles, much dissected ; the ultimate lobes 

 narrow, very acute and spreading : cauline leaves pinnatifid, with narrow 

 subulalely toothed segments. 



4. S. nudicaulis (Hook. & Arn.) : caulescent ; leaves mostly radical, on 

 very long petioles, cordate, 3-parted ; segments broadly obovate, somewhat 

 lobed, setosely toothed ; the lateral ones 2-cleft ; cauline leaves similar, two 

 opposite ones at the base of the 3-rayed umbel; calyx-tube ecliinate. — Hook. 

 6f Arn. hot. Beechey, suppl. p. 347. 



California, Douglas. — Among our Californian specimens of this genus, 

 collected by Mr. Douglas, is one which we think must be this species ; but 

 it seems to be a variety of S. laciniata, with less divided leaves. We have it 

 also from the same country, collected by Mr. Nuttall, under the name of 

 S. palmata.
