p. 107. Leaves somewhat lanceolate-oblong ; obtuse at the base, quite entire; downy beneath. Fruiton siiort thick stalks. (Hutnb. et Bonp.) A tree, from 25 ft. to 30 ft. high. Branches round, coveredwith minute tubercles; younger ones somewhat hairy. Leaves about 2 in. long, leathery; glabrousabove; covered with pale down beneath. Petioles about 2 lines long. Female flowers in the axilsof the leaves, almost solitary, on short thick pedicels. Cups somewhat top-shaped, closely imbricated.Scales oval, covered externally with a powdery down, acute. Nut ovate, terminated by the elongatedstyle. A native of the low mountains of New Spain, near Santa Rosa. Humboldt calied this speciesQ. crassipcs, from the extreme thickness and shortness of the stalks of the acorns. Its leaves ter-minate in a mucro.

Q. lanceolata Hutnb. et Bonp. PI. iEquin., t. 81., and our Jig. 1863., Michx. N. Amer. Syl., 1.p. 107. Leaves lanceolate, quite entire, wavy ; the axils of the veins bearded beneath ; shining above.Fruit sessile. Scales of the cup turned backwards.

( Humb. et Bonp.) A tree, from 30 ft. to 40 ft. high.

Branches alternate, covered with small tubercles,glabrous; younger ones, and the petioles, clothedwith stellate down. Leaves 2 in. to 3 in. long, and1 in. broad ; shining on both sides, leathery. Petiolesabout £in. long. Female flowers axillary, nearlysessile, and solitary. The cup is in the shape of agoblet, with the scales turned the contrary way ; oval,glabrous, and convex on the outside. Nut ovate,twice the length of the cup. A native of the tem-perate regions of New Spain, between Moran andSanta Rosa ; where it forms immense forests, at anelevation of 5400 ft. (900 toises). The wood is veryhard, and will last a long time when driven into theearth, or exposed to wet; on which account it ismuch esteemed by the Mexicans, and is used in theworks of the mines. This oak is remarkable for itsleaves, which are entire and wavy on the margin; forthe goblet-shaped cups of its acorns, the scales ofwhich all point towards the tree, instead of from it;and the property which is possessed by its wood ofresisting decay in water.

Q. reticulata Humb. et Bonp. PI. TEquin., t. 86.,and our Jig. 1865., Michx. N. Amer. Syl., 1. p. 110.

Leaves oboval; emarginate at the base; slightlytoothed towards the tip, rugged ; retlculately veinedand minutely downy beneath. Fruit sessile, on apedunculated raceme. (Hutnb. et Bonp.) A very loftytree; younger branches downy. Leaves 2 in. long, alittle, emarginate at the base. Female flowers in ax-illary solitary spikes, about the length of the leaves _ _

Cup campanulate, closely imbricate. Scales membranaceous, lanceolate, externally downy, attenuatedon both margins, somewhat recurved. Nut ovate, twice as long as the cup; terminated by the per-sistent style. A native of arid mountains in New Spain, between Guanajuato and Santa Rosa,forming considerable forests, at an elevation of about 6700 ft. (1450 toises). It attains a great height,and the trunk is straight, and of great diameter. The wood is used in building.

Q. chrysopkplla Humb. et Bonp. PI. JEquin., t. 87., and our Jig. 1864., Michx. N. Amer. Syl., 1.p. 108. Leaves oblong; obtuse at the base; 3—5-pointed at the apex; yellow beneath. Female flowersin many-flowered pedunculated clusters. (Humb. etBonp.) A tall tree; younger branches furrowed,as if with a powdery down. Leaves alternate, on long footstalks, 2in. long, membranaceous ; shining
