of Vermont Plants, 343 



Plants," and was prepared for the above work by William 

 Oakes, of Ipswich, Mass., a gentleman extensively known 

 as an eminent botanist. Of the forest trees of Vermont he 

 gives 52 species, with 6 species of smaller size, and many 

 species " of large shrubs, which sometimes become small 

 trees." Of forest trees -'found in Vermont, and not else- 

 where in New England," he enumerates : 



The Overcup White Oak. Quercus macrocarpa. 



The Northern Cork Elm. t/'lmus racemosa. 



The Heart- leaved Balsam Poplar. Populas Candicans. 



" The Ovcrcup White Oah belongs to the states of the West, and has not 

 been found even in New York. It was found in 1829, by Dr. Robbins, 

 in many towns on the western border of the state from St. Albans to Ben- 

 nington. It is distinguished by the great size of the acorn, and the 

 fringed border of the cup. 



The Northei-n Cork Bark Elm was first found in the state of New York, 

 and was described by Mr. Thomas, in Silliman's Journal, in the same 

 year (1829) that it was found by Dr. Robbins in Bennington and Pownal. 

 It is easily distinguished from the other New England species by the 

 broad plates of cork on its branches. 



Three fine species of Poplar, the two Balsam Poplars, and the magni- 

 ficent Vermont Poplar, Populus monilifera, are scarcely found unless cul- 

 tivated, in any other of the New England states. Neither of these three 

 Poplars, nor the Cotton Poplar, have been found native in New York by 

 the Botanists of that State, according to the late Report and Catalogue of 

 Dr. Torrey. (According to the younger Michaux, the Cotton Poplar is 

 found native in the west of New York.) 



The Vermont Poplar, and the Heart-leaved Balsam Poplar, which Dr. 

 Robbins found wild in many parts of Vermont, were not seen native in 

 North America by either the elder or younger Michaux, and do not ap- 

 pear to have been previously seen in a wild state by any Botanist in the 

 United States.
