l8 9*-] A Sketch of the Flora of Orono, Me. 233 



The kinds of trees composing these woods are hemlock, fir, 

 spruce, poplar, pine, maple, birch, beech, etc. The woods 

 about the College are thus of a mixed growth, coniferous trees 

 and soft wood predominating. The forests west and north on 

 rocky uplands have more hard wood species. The forests are 

 all second growth and none of the trees are of large size. 

 Hard woods suitable for lumbering purposes are very scarce. 

 The same is true of pine. The sugar maple occurs, but not 

 in sufficient abundance to make sugar-making a paying busi- 



ness. 



Acer dasycarpum Ehrh. grows along the banks of the river 

 between Stillwater and Orono villages. It is a tree of large 

 growth and often maintains a majestic, if not a magnificent 

 appearance. It is distinguished from A. rubrum L. by the sil- 

 very whiteness of the under surface of the leaves, whence the 

 trivial name. The branches are large and gradually expand- 

 ing as they ascend, often becoming recurved somewhat in the 

 manner of the elm. The wood is soft and fine grained, of 



moderate strength and perishable. 



By the river in front of the College we find Viola lanceolata 

 and Ranunculus Flammula, var. reptans. Potentilla palus- 

 tris and Campanula aparinoides are found in the meadow 

 below the farm house. On the side of the river opposite from 

 the farm house there grow two very attractive vines, Caly- 

 stegia sepium and Apios tuberosa. During the past season 

 there was found along this bank the noble Ostrich Fern (Stru- 



thiopteris Germanica Willd.). 



The variety of grasses upon the farm are those of com- 

 mon occurrence though there is a greater predominance oi 

 the better sorts. The bits of swale land, which are few. 

 contain the ordinary sedges and species of Glycena. I he 

 chief grasses which form the hay crop are timothy and red 

 top with occasional plants of brown top or fowl meadow 

 grass. With this hav there is mixed a small proportion of 

 several kinds of clover. The forage plants which have been 

 introduced by the present farm Superintendent are Hun- 

 garian millet and Alsike clover. 



There are but few weeds found in Maine which have not 

 been observed growing upon the College premises Last 

 season there was detected in a grain field a w. d which tin- 

 writer at least had not before observed, viz.: Camel. na it.va 

 Crantz. Darlington says this plant was introduced with Hax. 

 and remains as weed where the culture of that plant has been
