the under surface with woolly tomentura. Stipules persistent. Fruit sessile, almost solitary. ( Humb.et Bonp.) A tree, about 50 ft. high. Branches downy; younger ones brownish. Leaves about 3 in.long; younger ones downy above; adult ones thick and rigidly coriaceous; glabrous above, coveredwith yellow down benqath; obtuse and somewhat cmarginate at the base, acute at the apex; distinctlytoothed on the upper part. Petiole i in. to § 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. magnol icefolia Nee, and Q.lbtea Nee (see p. 1949.): but differs in the fruit being sessile, and disposed singly or in pairs in theaxils of the leaves; while, in Q. magndUcefblia and Q. Ihtea, the fruit is in racemes. It is easily knownfrom every other species of oak by its large persistent stipules. Michaux describes it as remarkablefor the thickness of its foliage.

Q. crassifolia Humb. et Bonp. PI. iEquin., t. 91., andour jig. 1869., Michx. N. Amer. Syl., 1, p. 110. Leaveswedge-shaped, oboval; emarginate at the base, remotelytoothed, repand; downy beneath. Peduncles short, bear-ing 1-3 acorns. {Humb. et Bonp.) A tree, from 40 ft. to50 ft. high. Branches downy, angled. Leaves from 3 in.to 4 in. long, thick, and rigidly coriaceous; covered withyellow down beneath ; teeth blunt, terminated by a mucro.

Cups sessile on the tips of short thick peduncles. Scalesroundish, downy. Nut spherical, very small, covered bythe cup. A native of New Spain, near Chilpancingo. It

is closely allied to Q. magno \icefblia and Q. lhtea Nee; . .

which two kinds Humboldt considers as forming only one species. Michaux mentions that it hasvery thick heavy-looking foliage; and that it is found in stony and mountainous places.
