The following list has been prepared from collections made in the Nortwest Territories of Canada during the seasons of 1879, 1880 and 1881, by Prof. John Macoun, Botanist of the Geological Survey Department of Canada.

During the summer of 1879 collecting was done, starting from Fort Ellice, thence to the head of Long Lake; thence to the elbow of the South Saskatchewan; then after crossing the river, in an almost straight line to Battleford; then south to the Hand Hills, and still south to Blackfoot crossing; thence west to Calgary, and up the Bow River to the gap in the Rocky Mountains.
