Collected by J. W. Tyrrell, C.E., D.L.S.,
in 1893, along the line of route between Lake Athabasca and the west coast of Hudson Bay; with which is incorporated a small collection made in 1885 at Ashe Inlet, on the north shore of Hudson Strait, and a collection made by Miss Marjorie Lofthouse at Fort Churchill.
The species collected from the Barren Lands are marked B; those from the forest country south of the Barren Lands, or in isolated groves of timber on the banks of the river, north of the general limit of the forest, are marked W. Any species collected both from the woods and from the Barren Lands are marked W.B., or B.W., according to whether they are woodland species extending into the Barren Lands, or Arctic species extending south into the forest.
