1944 ARBORETUM AND FRUTICETUM. PART JII. 
p. 107. Leaves somewhat lanceolate-oblong ; obtuse at the base, quite entire; downy beneath. Fruit 
on short thick stalks. (Humb. et Bonp.) A tree, from 25 ft. to 30 ft. high. Branches round, covered 
with minute tubercles; younger ones somewhat hairy. Leaves about 2 in. long, leathery ; glabrous 
above ; covered with pale down beneath. Petioles about 2 lines long. Female flowers in the axils 
of 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 elongated 
style. A native of the low mountains of New Spain, near Santa Rosa. Humboldt called this species 
Q. crassipes, from the extreme thickness and shortness of the stalks of the acorns. Its leaves ter- 
minate in a mucro. 
Q. lanceolata Humb. et Bonp. Pl. Zquin., t. 81., and our fig. 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 50 ft. to 40 ft. high. 
Branches alternate, covered with small tubercles, 
glabrous; younger ones, and the petioles, clothed 
with stellate down. Leaves 2in. to 3in. long, and 
lin. broad ; shining on both sides, leathery, Petioles 
about 2in. long. Female flowers axillary, nearly 
sessile, and solitary. The cup is in the shape of a 
goblet, 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 and 
Santa Rosa: where it forms immense forests, at an 
elevation of 5400 ft. (90U toises). The wood is very 
hard, and will last a long time when driven into the 
earth, or exposed to wet; on which account it is 
much esteemed by the Mexicans, and is used in the 
works of the mines. This oak is remarkable for its 
leaves, which are entire and wavy on the margin; for 
the goblet-shaped cups of its acorns, the scales of 
which all point towards the tree, instead of from it ; 
and the property which is possessed by its wood of 
resisting decay in water. 
Q. reticulata Humb. et Bonp. Pl. Aquin., t. 86., 
and our fig. 1865., Michx. N. Amer. Syl., 1. p. 110. 
Leaves oboval; emarginate at the base; slightly 
toothed towards the tip, ru, 3; reticulately veined 
and minutely downy beneath. Fruit sessile, on a 
pedunculated raceme. (Humb.et Bonp.) A very lofty 
tree; younger branches downy. Leaves 2in. long, a 
little emarginate at the base. Female flowers in ax- 
illary solitary spikes, about the length of the leaves : mo + 
Cup campanulate, closely imbricate. Scales membranaceous, lanceolate, externally downy, attenuated 
on 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 6/00 ft. (1450 toises). It attains a great height, 
and the trunk is straight, and of great diameter. The wood is used in building. 
Q. chrysoph¢lila Humb. et Bonp. Pl. Aquin., t. 87., and our jig. 1864., Michx. N. Amer. Syl, 1. 
p. 108. aves oblong ; obtuse at the base ; 3—5-pointed at the apex ; yellow beneath. Female flowers 
in many-flowered pedunculated clusters. (Hiumb. et Bonp.) A tall tree; younger branches furrowed, 
as if witha powdery down. Leaves alternate, on long footstalks, 2in. long, membranaceous ; shining
