The only reported station is Saucelito Hills, near San Francisco, Cali- 
fornia (Kellofig cf- Harford). 
4. S. Dawsoni C. & R. Bot. Gazette, xiii. 144. A foot or 
so high, glabrous: leaves ternate then pinnate, the small ( ^ to 
inch long) ovate acute segments laciniately toothed to entire: um- 
bel with involucels of linear-oblong scarious bractlets longer than 
the pedicels and abruptly ending in a long attenuation; pedicels 1 
to 2 lines long: fruit oblong, smooth, about 2 lines long, v/ith 
prominent wings, the lateral ones but little broader; rarely an ad- 
ditional small oil-tube in a lateral interval: seed hardly at all dor- 
sally sulcate. (Fi g. 20.) 
Felly Kiver, at Felly Banks, Yukon, lat. 61°, August 11, 1887 (Daui- 
.‘ion 23). 
This interesting species is quite distinct from all other species of 
Selinum in its leaf and involucel cliaracters, as well ac in the prominent 
thin wings of the fruit. 
5. S. Grayi C. & R. Bot. Gazette, xiii. 144. Stout, some- 
times very much so, 1 or 2 feet high, glabrous except the more or 
less scabrous inflorescence, leaf-margins and veinlets (beneath): 
leaves once or twice pinnate, with much dilated petioles; leaflets 
oblong to ovate, about an inch long, acute, toothed (sometimes 
laciniately toothed or lobed ) : umbel with involucels of conspicu- 
ous lanceolate-ovate long-acuminate bractlets; rays 1 to 2 inches 
long; pedicels 1 to 2 lines long: fruit oblong, smooth, 2 to 2^ lines 
long, with prominent thin wings; the laterals decidedly broadest: 
seed-face dorsally sulcate. (Fig. 21 .) — Archmtgelica Gmelini of 
FI.’ Colorado and Coulter’s Rockv Mt. Manual. 
High mountains of Colorado (Parry 154, Vasey in 18f)8, Canby in 1871, 
Coulter, Wolf cf* Rothrock in 1873, Letterman in 1884, Trelease in 1886, 
etc.) 
This plant has always been distributed as Archang elica Gmelini, hav- 
ing been wrongly referred to that species. So far as we have seen, most of 
the Arehangelica Gmelini reported from Colorado is this species. Its 
general habit resembles that of an Angelica somewhat, but its fruit char- 
acters are very different and are entirely those of Selinum. 
6. S. Benthami Watson, Bibl. Index Polypet. 432. Gla- 
brous throughout: leaves ternate then pinnate, the oblong to linear- 
oblong acute segments to ^ inch long, laciniately toothed or 
lobed to entire : umbels on stout peduncles, 10 to 15-rayed, with an 
involucre of a few linear setaceous bracts, and involucels of several
