Spec. Char., $c. Leaves oblong, smooth ; glaucous beneath ; deeply and un- 

 equally pinnatifid. Fruit elliptic ovate, on short footstalks. Calvx cup- 

 shaped, fringed, and nearly covering the acorn. (Michx. t adapted.) This 

 tree grows, in America, to the height of from 

 60 ft. to 70 ft. ; and, according to Michaux, 

 it has a spreading head, and an imposing 

 aspect. " The bark is white and laminated ; 

 but the tree is chiefly remarkable for the form 

 and disposition of its secondary branches, 

 which are slender and flexible, and always 

 inclined towards the earth. This peculiarity 

 alone," continues Michaux, u would render 

 it a valuable acquisition for parks and gar- 

 dens." (N. Amer. Syl., i. p. 33.) The leaves 

 are of a light green above, and whitish be- 

 neath : they resemble those of the white oak 

 in colour, but differ from them in form ; being 

 larger, and very deeply and irregularly lacini- 

 ated, with rounded lobes, so different in 

 shape, that it is impossible to find two leaves 

 that are alike. The acorns are of an elon- 

 gated form, and are about three parts en- 

 closed in deep oval cups, the scales of which 

 are prominent and recurved, except near the 



, where they terminate in slender flexible filaments. From this pe- 

 .rity, Michaux called the species the mossy-cupped oak. This oak 

 is very rare in America, being only found, according to Michaux, on the 

 banks of the Hudson above Albany, and in Genessee : but Pursh found 

 it on iron ore hills in Pennsylvania and Virginia. Pursh adds that, in 

 general appearance, it resembles Q. macrocarpa. Michaux thinks that 

 the wood, though " not better than that of Q. alba, is far superior to that of 

 Q. rubra ;" but it does not appear that it has been yet applied to any econo- 

 mical uses. It was introduced into England in 1811, but is seldom found 

 in plantations, or even in the nurseries. There are seedling plants of it in 

 the Horticultural Society's Garden ; and in some private collections.

Spec. Char., $c. Leaves downy beneath, lyrate, deeply and sinuately lobed; the 

 lobes obtuse and spreading, and the upper one much dilated. The calyx deep, 

 cup-shaped, scaly, and fringed with bristles. Acorns thick and ovate. ( Willd.) 

 This, according to Michaux, is " a beautiful tree, more than 60 ft. high, laden 

 with dark tufted foliage. The leaves are larger than those of any other oak 

 in the United States, being frequently 15 in. long, and 8 in. broad : they are 

 notched near the summit, and deeply laciniated below. The acorns, which 

 are also larger than those of any other American species, are oval, and en- 

 closed for two thirds of their length in a thick rugged cup, which is generally 

 bordered along its upper edge with fine, long, flexible filaments. The bark
