ROCKY-MOUNTAIN OAK. 
QUERCUS undtjlata; fruticosa ramosissima; foliis peren- 
nantibus brevipetiolatis oblongis acutis sinuato-dentatis 
dentibus acutis, basi cuneatis, subtus pulverulento-tomento- 
sis, supra nitidis ; fruciibus subsolitariis sessilibus, cupula 
hemisphserica squamis appressis, glande ovata acuta. Tor- 
rey in the Annals of the Lyceum of New York, vol. 2, p.

This dwarf Oak, considerably allied to our small 
leaved preceding species, was discovered by Dr. James, in 
Long’s Expedition, towards the sources of the Canadian, 
a branch of the Arkansa, and likewise in the Rocky 
Mountains. It is said to be a small straggling shrub, 
with the under surface of the leaves clothed with a close 
whitish tomentum or down, more or less spread, though 
more thinly, also on the upper surface, with the hairs 
stellated. The leaves are small, and somewhat resemble 
those of the Holly, about an inch and a half or two 
inches long, rather narrowed at the base, of a thick and 
rigid consistence, as in all the sempervirent Oaks, reti- 
culately veined beneath, with the margin sinuately 
toothed, but not that I can perceive waved, as the spe- 
cific name implies; the teeth sharp and acute at the 
points; above somewhat shining and minutely pubescent. 
The acorns are large and strongly resemble those of the 
Live Oak; they are, however, without stalks, and grow 
alone or in pairs; the cup is deep and hemispherical, 
with the scales pointed. 
It is so nearly allied to the Holly Oak of the South of 
Europe ( Quercus Ilex), that it is necessary to distinguish 
them. In our plant the base of the leaf is wedge-formed;
