Hab. N. W. America. Menzies {in Herb, nostr.) Plentiful on the plains near Fort Vancouver, on the 

 Multnomak, and at Puget Sound, Douglas. I>r Gairdner, Tolmie.—V oxiy to eightj^ feet high, 3-5 in dia- 

 meter : the wood good, and well adapted for ship-building. This Oak, which I believe to be a very distinct 

 species, has not only the underside of the adult leaves, but the petioles and branches, clothed with a dense 

 dingy-coloured down. The leaves, too, are much broader than in Q. alba, the acorns are sessile, and the 

 cups much shallower. There is an Oak in Mr Drummond's third collection of Texas plants (No. 342), 

 named " Yellow Post Oak," distinguished by the downy leaves and the size of the acorns, in which the leaves 

 and sessile acorns agree with those of the present species very closely ; but the branches are glabrous, and 

 the cups are ranch deeper, and clothed with larger and more hoary scales. — Mr Menzies also detected Q, 

 Garryana in California, where Mr Douglas, besides the Q. agrifolia, Nee, gathered also a third species, 

 with leaves somewhat like the present, but narrower, and with narrower lobes, nearly glabrous beneath, and 

 much smaller acorns. These three are, as far as I know, the only Oaks yet discovered in N. W. America. ,

1. C chrysophylla (Dougl. mst.) ; foliis sempervirentlbus lato-lanceolatis acuminatis 

 coriaceis integerrimis glabris subtus aureo-farinosis. 



Hab. Common on the Grand Kapids of the Columbia, to Cape Orford, and near Mount Hood ; constantly 

 inhabiting the hills. — This is a most splendid evergreen tree, varying in height from 20 to 70 feet, with 

 leaves 4-5 inches long, full green above, below of a rich golden yellow. These leaves are quite entire. The 

 spikes or catkins of flowers scarcely exceed an inch in length, including the peduncle,'and they are soli- 

 tary in the axils of the upper leaves -, sometimes all the flowers on a catkin are male ; sometimes the two or 

 three lower flowers are female. Fruits 2-3, crowded, densely clothed with aclcular prickles.

Hab. Canada, New Brunswick, and Newfoundland. — This is the '^ Bed Beech/' of the inhabitants, and 

 I, like Dr Torrey, have only seen this one species from any part of N. America; but Michaux, and Ameri- 

 can authors, describe another species as also inhabiting Canada, namely—

Hab. Canada. Michaux, who calls this the " White Beech," from the difference of the colour of the 

 wood in the two kinds ; but neither in Michaux's figure, nor in the description of authors, docs their appear 

 any marks by which this can be separated botanically from the preceding. In both, the leaves vary somewhat 

 in shape, but are at all times much larger and longer and more toothed than in the European Beech, which 

 has, moreover, the prickles of the fruit straight, and not clothed with ferruginous down, j
