^ecimens from Mr. Cleghorn, and now it has been found by Dr. Todd at Pentangiiishene on Lake Huron, 

 exactly on the borders of the United States; and, by Dr. Richardson it was ascertained to extend its range 

 as far as the plains of the Saskatchawan, in lat. 54°. It is difficult to say to what division of the genus it shoiUd 

 belong- J its unequal calyx allies it with " Asa/ria," its foliaceous sepals with " Bathn/s," its habit with 

 ** Perforaria," where I have placed it. So much are the styles united, that the flowers may be said to be 

 monogynous; yet in the axils of the corymb some of the pistils as they advance to maturity arc found to 

 have their styles more or less divided; but I do not observe this to be the case -with the upper flowers.

Hab. Abundant in dry g^velly soils and limestone rocks on the North-West coast of America, near 

 the Columbia. Dr. Scouler; Douglas. — Flowers about the size of those of H» dubium. Petals, stwiiens, and 

 states long", and about equal in length. Leaves of a rigid and somewhat coriaceous texture, turning brown

Hab. Canada, (Michaux,) most abundant near the southern lakes. Douglas; Dr, Todd; Mrs. PercivaL 

 Mr. Douglas observes that its northern limit is at Lake Winipeg, where it is of diminutive stature. — This is 

 a beautiful small tree, with smooth bark, streaked with lono^tudinal white lines, whence in some parts of 

 the United States it is called Striped Maple, while in othei-s it is named Moose- Wood, from the circumstance 

 of the Moose-Deer subsisting during severe weather upon its young twigs. The leaves have their lobes 

 sinoTilarly acuminated and most finely serrated. Its buds and leaves are among those of the earliest of the 

 American trees to announce the approach of Spring; and, when beginning to unfold, are of a delicate rose- 

 colour, which soon changes to green. The wood is said by Michaux to be white, and used instead of Holly. 

 Horses and cattle are turned into the woods to feed on the young shoots at the latter end of winter. — Ra-. 

 cemes long. Flowers large.
