sessili quadrifido. S. phylicifolia, Smith. Comp. Fl. Br. p.146 1 Engl. Bot. 1 .1958 ? (W.)
Folia sesquipollicaria, exstipulata, pube sericea caduca ? vestita, subtus grisea sub-glauca. Amenta
foeminea sæpe ferè palmaria pedunculata foliis tribus quatuorve fulcràta. Squamoe ellipticæ pallide brunneæ
pilosæ. Pedicelli primo squamas vix superantes mox ad longitudinem unguicularem elongati et squamis

being perfect.
416. Empetrum n i g r u m , Willd. iv. p. 713. Pursh. i. p. 93. (W.B.)
In high northern latitudes its berries, after the first frosts, are very juicy and pleasant. They are
hoarded up by the different species of marmots, and form the autumnal food of the Anas hyperborea.
417. Myrica gale, Willd. iv. p. 745. Pursh.ii. p. 618. (W.)
The Indian women use the buds of this plant to dye their porcupine quills with.
418. Populus trépida, Willd. iv. p. 803. Pursh. ii. p. 618. (W.)
Hab. From Hudson's Bay to the northward of Great Slave Lake, as far as lat. 64°. It is denominated
by the Créés, Metoos, and is esteemed to burn better in a green state than any other tree in the country.
419. P. balsamifera, Willd. iv. p. 805. Pursh. ii. p. 618. (W.)
The trunk of this tree attains a greater circumference than that of any other in the northern parts of
America. It bums badly, and gives little heat when green, but its ashes yield a large quantity of potash.
We traced it as far to the north as Great Slave Lake, and the south branch of Mackenzie’s River has
been named Rivière aux Liards, from its abundance in that quarter. It constituted the greatest part of the
drift timber that we observed on the shores of the Arctic Sea. Its Cree name is Matheh-metoos (ugly
poplar.) ' ’ ' '■ ' ‘ ■ |p | ; ”
420. Juniperus communis. Willd. iv. p.S53. Pursh. ii. p. 647. (W.)
Its fruit is termed Caw-caw-kew-meena, (crow-berry), by the Créés.
421. J. prostrata, Pers. enchir. ii. p. 632. (W.)
It is nearly as common as the other species, grows close to the ground, and sends out flagelliform
branches two yards long. It is a very ornamental plant in thin rocky soils.
422. Hippophae canadensis, Willd. iv. p. 744. Pursh. i. p. 115. (W.B.)
423. Negundo fraxinifolium, D.C. prodr. i. p.596? Acer sacch. Frankl. App.

Obs. The Saskatchawan is the northern boundary of this tree, and even there pretty good sugar i3
made from its juice. We saw only the male flowers ; and the tree was not in leaf when we were in that
quarter.
