the under surface with woolly tomentum. Stipules persistent. Fruit sessile, almost solitary. (Humb. 
et Bonp.) A tree, about 50 ft. high. Branches downy ; younger ones brownish. Towebon 3in. 
long; younger ones downy above ; adult ones thick and rigidly coriaceous; glabrous above, covered 
with yellow down beneath ; obtuse and somewhat emarginate at the base, acuteat the apex ; distinctly 
toothed on the upper part. Petiole }in. to 2 in. long, thick, tomentose. Stipules linear-lanceolate, 
persistent. Female flowers axillary, sessile, solitary or twin. Cup composed of roundish, membrana~ 
ceous, downy scales. A native of the mountains of Mexico, near Actopan ; forming entire forests, 
at an elevation of 7900 ft. (1330 toises). It has a great affinity with Q. magnoliefélia Nee, and Q. 
litea Nee (see p. 1949.) ; but differs in the fruit being sessile, and disposed singly or in pairs in the 
axils of the leaves; while, in Q. magnolief dla and Q. lutea, the fruit is in racemes, It is easily known 
from every other species of oak by its large persistent stipules. Michaux describes it as remarkable 
for the thickness of its foliage.

Q. crassifdlia Humb. et Bonp. Pl. Aquin., t. 91., and 
our fig. 1869., Michx. N. Amer. Syl., 1. p. 110. Leaves 
wedge-shaped, oboval; emarginate at the base, remotely 
toothed, repand ; downy beneath. Peduncles short, bear- 
ing 1-3 acorns. (Humb. et Bonp.) A tree, from 40 ft. to 
50 ft. high. Branches downy, angled. Leaves from 3in. 
to 4in. long, thick, and rigidly coriaceous; covered with 
yellow down beneath ; teeth blunt, terminated by a mucro. 
Cups sessile on the tips of short thick peduncles. Scales 
roundish, downy. Nut spherical, very small, covered by 
the cup. A native of New Spain, near Chilpancingo. It 
is closely allied to Q. magnoléefoléa and Q. litea Nee; 
which two kinds Humboldt considers as forming only one species. Michaux mentions that if has 
very thick heavy-looking foliage; and that it is found in stony and mountainous places. 
Q. depréssa Humb, et Bonp. Pl. Aquin., t.92., and our jig. 1871., Michx. N. Amer. Syl. 1. 
p. 108. Leaves oblong-oval, acute, entire, rarely mucro- 
nate; dentate, evergreen, quite glabrous. Fruit nearly 
sesssile, and solitary. (Humb. et Bonp.) An evergreen 
shrub, from 1ft. to 2ft. high. Branches alternate, ap- 
proximate, about the thickness of a goose-quill; younger 
ones covered with a peculiar powdery down. Leaves lin. n r 
to 1 in. long; glabrous on both sides, shining, rigid, on very short petioles. Catkins downy. Calyx 
small, 4—5-toothed, downy. Stamens 7—11, three times as long as the calyx, erect. Anthers ovate,
