ARBORETUM AND FRUTICETUM. 



PART III. 



the under surface with woolly tomentura. Stipules persistent. Fruit sessile, almost solitary, {ffumb. 

 et Bunp.) A tree, about 50 ft. hinh. Branches downy ; younger ones brownish. Leaves about 3 in. 

 long; younger ones downy above ; adult ones thick and rigidly coriaceous ; glabrous above, covered 

 with yellow down beneath ; obtuse and somewhat cmarginate at the base, acute at the apex ; distinctly 

 toothed on the upper part. Petiole \ in. to J in. long, thick, tomcnto.^e. Stipules linear-lanceolate, 

 persistent. Female flowers axillary, sessile, solitary or twin. Cup comijosed of roundish, membraua- 

 rcous, 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 groat affinity with Q. magnoiuefoiia Nee, and Q. 

 liitea ^ee (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. magnol;>/i/m and Q. liitea, thefruit 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. crassifolia Humb. et Bonp. PI .Squin., t. 91., and 

 our Jig. 18b9., 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. ei Bonp.) A tree, from 40 ft. to 

 50ft. high. Branches downy, angled. Leaves from Sin. 

 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. magnoUipfUia and Q. li\tea Nee; 



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

 very thick heavy-looking foliage ; and that it is found in stony and mountainous places. 



Q. depressa Humb. et Bonp. PI. jEquin., t. 92., and our fig. 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 2 ft. high. Branches alternate, ap- 

 proximate, about the thickness of a goose-quill ; younger 

 ones covered with a peculiar powdery down. Leaves 1 in. 

 to 11 in. long ; glabrous on both sides, shining, rigid, on very short petioles. Catkins downy. Calyx 

 small, 4 — .5.toothe<l, downy. Stamens 7—11, three times as long as the calyx, erect. Anther* ovate.
