 eeous, downy seales. A native of the mountains of Mexico, near Actopan ; forming entire forests, 

 at an elevation ot ^XV ft. (1880 toises). It has a great affinity with Q. magnotte/o/tVl Nee, and Q. 

 \ v see p. 1949. > ; but differs in the fruit beine: sessile, and disposed singly or in pairs in the 

 axils ot the leaves ; while, in (I magnol/Vr/" biia and Q. Ihtea, the fruit is in racemes. It is easily known 

 from every other speeies of oak by its large persistent stipules. Michaux describes it as remarkable

Q. crassifblia Humb. et Bonp. PI JEquin., t. 91., and 

 our fig. 18ti9., 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. ct Bonp.) A tree, from 40 ft. to 

 90ft. high. Branches downy, angled. Leaves from 3 in. 

 to 4 in. 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. magnoUa-Jolia and Q. lutea Nee; 

 which two kinds Humboldt considers as forming only one species. Michaux mentions that it has 

 verv thick heavy-looking foliage: and that it is found in stony and mountainous places.
