408 Florulu Leiingtoniensi 



Obs, Not so common as the preceding, being more restrict- 

 ed to the borders of water courses. It is in every point ..f vi w 

 less valuable than the Sugar tree, although the sap isocrasion- 

 ally procured in common with that of the former, in the making 

 of sugar. Flowers at the same time. 



Species 3d. Acer Dasvcarpum. White Maple, 



Sp, Ch» Leaves palmate, 5 — lobed, acuminate, serrate, pubes- 

 cent underneath, and almost white ; ^ozyer^ in clustered um- 

 bels; ^crm5 tomentose. 



Ohs, This tree, which in its general habit resembles the 

 Su^ar Maple, is however easily distinguished from it by the 

 IL/hf er and smoother colour of the bark, and the singular downy 

 wliiteness of the leaves. It attains as large a size and is valua- 

 ble as fuel and for some of the mcclmnic arts. Sugar is also 

 made from its sap, but it is now rarely met with in tiiis neigh- 

 bourhood.

 late, nearly entire. Flowers axillary, solitary, nearly sessile. 

 Corolla small, white and, like both the following, very cadu- 

 cous. Capsule inversely heart-shaped and larger than either 

 of the succeeding species. — The plant has had some reputation 

 in scrofula, hence the name of Neckw^eed. Flowers middle of 

 March and after. Abundant in gardens and cultivated fields.
