British CotumBiA: Type specimens as cited under type locality. 
6. Angelica arguta Nutt. in Torr. & Gray FI. 1: 620. 1840. 
Glabrous, except the sometimes minutely puberulent inflorescence, 
stout, 6 to 12 dm. high; leaves ternate then pinnate or bipinnate; 
leaflets mostly small, ovate to lanceolate, rather acute, serrate; umbel 
‘ather equally many-rayed, with neither involucre nor involucels; rays 
9.5 to 7.5 em. long; pedicels 6 to 10 mm. long; fruit oblong-elliptical, 
glabrous, 6 to 8 mm. long; dorsal and intermediate ribs thick and 
slightly elevated; lateral wings very corky, thick, and as broad as the 
much-flattened body or broader; oil tubes 2 on the commissural side, 
distant, or sometimes 4 in two distant pairs; seed sulcate beneath the 
oil tubes, with plane face. 
Type locality said to be ** Wappatoo Island and near Fort Van- 
couver,” in the Lower Columbia River Basin; collected by Vuttal/ ; 
type in Herb. Torrey.

In the Revision we stated that ‘this plant was reported by Nuttall from ‘ Fort 
Vancouver, Oregon,’ and then lost sight of, being confused with A. genuflera, An 
examination of the type (in good fruit in the Torrey Herbarium) abundantly con- 
firms our conclusions given in Botanical Gazette xiii, 80.’’ Unfortunately no new 
material of this species has come to light during the last twelve years, which has led 
some of our best Western collectors to doubt our conclusions. Nuttall, who collected 
the type, obtained it (at least in part) from Wappatoo Island, in the Lower Colum- 
bia. At the same place he collected Angelica genufleca and Archangelica.peregrina. 
The inference has been that these three species are one and the same. Mr. L. F. 
Henderson has collected extensively in recent years on this island, and has found 
only one species. This has led us to reexamine the type, and our opinion is that 
A, arguta is different from A. genuflera, It seems much nearer A. lyalli, to which 
we were once constrained to refer it. It grows at so much lower elevations, however, 
that it seems impossible to consider the two identical. 
7. Angelica lyallii Watson, Proc. Am. Acad. 17: 374. 1882. 
Glabrous except the sometimes puberulent inflorescence, stout, 6 to 
15 dm. high; leaves ternate then once or twice pinnate, the upper- 
most reduced to large inflated petioles; leaflets extremely variable in 
size, ovate to lanceolate, rather acute, serrate or dentate; umbel many- 
‘ayed, with neither involucre nor involucels; rays 2.5 to 25 em. long; 
pedicels 2 to LO mm. long, coalescent at base (giving ¢ ‘*web-footed” 
appearance); fruit oblong to obovate, glabrous, 4 to 6 mm. long; dor- 
sal and intermediate ribs thick and slightly elevated; lateral wings as 
broad as the often much flattened body or broader; oil tubes solitary 
in all the intervals. 
Type locality, ‘in the Galton and Cascade Mountains, near the British 
boundary;” collected by Dr. Lyall. 
In the mountains, from eastern Oregon to northwestern Wyoming 
and northward to Alberta.
