toba west to the Rockies, common, however, west of the Rockies in British 
Columbia, Seattle, and other points in Manitoba. The V. BlaUaria com- 
mon eastward in Utah and the Pacific coast. 
The Foxglove {Digitalis purptirea) frequently cultivated as an orna- 
mental plant on the coast, is a frequent escape and one finds patches of 
the escaped plants frequent in Oregon, Washington, and western British 
Columbia. The Toadflax {Linaria vulgaris) is common east and north. 
I might mention here, also, that the Linaria Cy mb alarm of the same 
family, and common Pansy {Viola t7icolor) of the Violaceae, is an escape 
from cultivation in Washington and Oregon. The Petunia, Dianthus, 
Phlox, objects of careful cultivation, are more or less weedy in Wash- 
ington and Oregon. 
A few weeds of the Goosefoot Family, Chenopodiaceae, are widely 
distributed in the northwest. The Russian Thistle {Salsola Kali var. 
tennifolia) which at one time threatened to spread over the corn belt, 
as it was injurious in the wheat belt of the Dakotas and the Northwest, 
is abundant in some localities, along the right of way of railways and 
sandy soil in Minnesota, Wisconsin and Iowa, and common along railways 
and locally from Winnipeg west to the coast although not nearly as 
freciuent as it is in Colorado, Utah and the drier regions of the west to the 
coast where it has found a congenial home. The common Lamb’s quarter 
{Chenopodkini album) is common across the continent from St. Paul 
to Seattle and from Omalia to Salt Lake and from Winnipeg to Vancouv- 
er. It follows the railways across the continent. The species was found in 
Banff, Sicamous Junction and Crow’s Nest Pass, more abundant in 
southern Manitoba and in Minnesota than in Alberta and Saskatchewan. 
The Large Goosefoot {Clienopodiiim hybridum) common in Minnesota 
and Winnipeg and Winnipeg Beach and in many places of Minnesota, 
AVisconsin, Missouri and Illinois. The Cheiiopodium glauoum found 
rather common about the great lakes also occurs in Winnipeg and AVinni- 
peg Beach, where it is common. 
The AVestern Pigweed {Monolepis Nuttalliana) is common in Saskatch- 
ewan and Alanitoba, it is of more frequent occurrence in fields than the 
common Goosefoot and more abundant than the Russian Thistle in that 
region. It has not reached Iowa although found in Alinnesota and re- 
ported from Alissouri by Robinson and Fernald. It occurs in all of the 
provinces from AALnnepeg to British Columbia. 
The species of weeds of the Pink Family, Garyophyllaceae, are not 
numerous. The Cowherb {Saponaria Vaccaria) occurs in the wheat 
growing section of the northwest frequent in Minnesota and Dakota,
