Michaux the younger observes, that this oak is the only species which ever grows in the most fertile districts of East Tennesee, or Holston; and which last place is inferior in every respect to Cumberland and Kentucky in fertility. However he found it growing in cool mountainous places, and by the sides of the rivers, which have not steep banks, at Kentucky and Cumberland, with acorns as large as a hen's egg. The state of Kentucky is situated between 36o 30' and 39o 30′ of latitude, and between the $2 and $99 of longitude.

ing species, of a dark green, and less rough to the touch; with petioli, or leaf-stalks, much longer. FRUCTIFICATION. Fruit very large: cup deep and hairy near its edge: acorn oval; sometimes more swelled; shut up in its cup, before it becomes ripe: peduncle, or fruit-stalk rather long.

COUNTRY. All the countries to the west of the Allegany mountains, Kentucky, Tennassee, Illinois, &c.

OBSERVATIONS.

This oak yields wood of a good quality, when it grows in elevated clays, and calcareous soils, as those of Kentucky and Tennassee; but in marshy grounds it appears weakly, and covered with lichens. Michaux seems to think, that in such situations the wood is not good, and its growth is retarded. Its young branches are covered with a fungous-like substance, like those we meet with on the elm, and liquidamber, which disappears in proportion as they become more full grown. There are found under the leaves of this species of oak small galls, in shape like lentils, and very hairy, and also very large ones, like the galls of other oaks, but they are light, membraneous, and empty; yet ink can be made of them.

Michaux the younger notices this species but once in his Travels, growing in the Pine Barrens, or swamps in Carolina and Georgia.
