introduced.

dida, ad ostium fl. Coppermine lecta erat. Folia caulina vix semuncialia, oblonga, lanceolatave nunc ob-
tusa, nunc acuta, semper puncto calloso magis aut minus manifesté apiculata, cum caulibus striatis,- pedun-
culis, bracteis et calycibus pilis laxis viscidis vestita: margines foliorum pilis crebrioribus ciliati sunt. Pa-

time we referred to C. latifolium L. gathered on the shores of the Arctic Sea, were in the collection that
was lost.

The tawquoy-meen-ahtick of the Créés is a handsome small tree, rising on the sandy plains of the Saskat-
chawan to the height of twenty feet, but extending as far north as Great Slave Lake, where it attains the
height of five feet only. Its fruit, termed Tawquoymeena, or Choke-cherry, is not very edible in a recent
state, but when dried and bruised, forms an esteemed addition to pemmican.

This shrub is common as far north as lat. 62°. It abounds on the sandy plains of the Saskatchewan. Its
wood, named by the Crees meesassquat-ahtick, is prized for making arrows and pipe stems, and is thence
termed by the Canadian voyagers bois de fleche. Its berries, about the size of a pea, are the finest fruit
in the country, and are used by the Crees under the name of Meesasscootoom-meena, both in a fresh and
dried state. They form a pleasant addition to pemmican, and make excellent puddings, very little inferior
to: plum-puddings.
