Spec. Char., tfc. Leaves oblong, smooth; glaucous beneath ; deeply and un-equally pinnatifid. Fruit elliptic ovate, on short footstalks. Calyx cup-shaped, fringed, and nearly covering the acorn. {Michx., adapted.) Thistree grows, in America, to the height of from60 ft. to 70 ft.; and, according to Michaux,it has a spreading head, and an imposingaspect. “ The bark is white and laminated;but the tree is chiefly remarkable for the formand disposition of its secondary branches,which are slender and flexible, and alwaysinclined towards the earth. This peculiarityalone,” continues Michaux, “ would renderit a valuable acquisition for parks and gar-dens.” {N. Amer. Syl., i. p. 33.) The leavesare of a light green above, and whitish be-neath ; they resemble those of the white oakin colour, but differ from them in form ; beinglarger, and very deeply and irregularly lacini-ated, with rounded lobes, so different inshape, that it is impossible to find two leavesthat are alike. The acorns are of an elon-gated form, and are about three parts en-closed in deep oval cups, the scales of whichare prominent and recurved, except near theedge, where they terminate in slender flexible filaments. From this pe-culiarity, Michaux called the species the mossy-cupped oak. This oakis very rare in America, being only found, according to Michaux, on thebanks of the Hudson above Albany, and in Genessee: but Pursh foundit on iron ore hills in Pennsylvania and Virginia. Pursh adds that, ingeneral appearance, it resembles Q. macrocarpa. Michaux thinks thatthe wood, though “ not better than that of Q. alba, is far superior to that ofQ. rubrabut 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 foundin plantations, or even in the nurseries. There are seedling plants of it inthe Horticultural Society’s Garden; and in some private collections.

Spec. Char., fyc. Leaves downy beneath, lyrate, deeply and sinuately lobed; thelobes 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, ladenwith dark tufted foliage. The leaves are larger than those of any other oakin the United States, being frequently 15 in. long, and 8 in. broad : they arenotched near the summit, and deeply laciniated below. The acorns, whichare 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 generallybordered along its upper edge with fine, long, flexible filaments.
