above, covered with fine yellow tomentum beneath. Male catkins aggregate, situated beneath the 
female flowers. Male flower: calyx 5-toothed, stamens 6, anthers ovate, pollen yellow. Fe- 
male flowers 4-6, sessile, on the apex of a peduncle about 3 in. long. Female flower : ovary globose ; 
atyles or stigmas 5, red, thick A native of New Spain, between Moran and Pachuca. @. chryso- 
phfila, as well as the preceding species, is found forming entire forests between Moran and Pa- 
1864 
chuca, at an elevation of 8400 ft. (1400 toises). It is re- 
markable, on account of the position of its female flowers, 
which are placed under the male flowers ; and also for the 
beautiful golden colour of the under surface of the leaves ; 
a peculiarity which distinguishes it from every other de- 
scribed species of oak. Michaux mentions that this tree 
is remarkable for the thinness of its foliage. 
Q. pulchélla Humb. et Bonp. Pl. Aquin., t. 88., and 
our fig. 1866., Michx. N. Amer. SyL, 1. p. 110. Leaves 
oblong, obtuse; emarginate at the base; covered with 
white down beneath ; teeth short, mucronate. Fruit ses- 
sile, almost solitary. (Humb. et Bonp.) A shrub from 12 ft. 
to 18 ft. high, with a trunk about 2ft. in circumference, and a smooth bark. Branches alternate, 
round, covered with tubercles, or callous dots. Leaves crowded towards the tips of the branches ; 
1} in. to 2in. long, on longish footstalks, leathery, wavy on the margin; shining above, reticu- 
lately veined and co- 
vered with white 
down beneath. Fe- 
male flowers axil- 
lary, solitary,or twin. 
Cup spherical. Scales 
roundish-oval, close- 
ly imbricated; ex- 
ternally downy on 
the back, membrana- 
ceous. Nut ovate, 
scarcely longer than 
the cup. A native of 
the mountainous re- 
gion of New Spain, 
between Guanajuato 
and Santa Rosa, at 
an elevation of 8400 
ft., (1400 toises). It 
has considerable af- 
finity with Q. side- 
réxyla (p. 1943.) ; but 
it differs in its height 
and habit of growth; inthe form and consistency of its leaves ; 
in their being cut in their petioles, and, lastly, in the size of 
its fruit, which are larger than in Q. sideréxyla. 
Q. spicata Humb. et Bonp. Pl. Zquin., t.89., and our fig. 
1867., Michx. N. Amer., 1. p. 111. Leaves elliptic or 
obovate, e inate at the base, remotely toothed, downy be- 
neath. F ie spike on a long footstalk. (Humb. et Bonp.) 
A tall tree, from 30 ft. to 40ft. high. Branches and youngs 
leaves covered with clusters of down. Leaves on short foot- 
stalks, somewhat wedge-shaped, oboval, or for the most part 
elliptic; roundish-obtuse ; glaucous and shining above, to- - 
mentose beneath ; and, in some, reticulately veined, downy. Female flowers in spikes or sessile 
racemes, distinct. Cup hemispherical. Scales closely imbricated, oblong, blunt, externally convex, 
downy. Nutovate. A native of shady situations in the mountain of Nabajas, in Mexico, at an 
elevation of 9000 ft. to 9500 ft. (1487 to 1590 toises). It appears allied to Q. elliptica, described by 
Nee in the Anales de las Ciencias Naturales, 1801. The leaves are not entire, but are denticulated 
in the upper half: they are furnished with short thick footstalks, membranaceous, and not cori- 
aceous ; and, instead of being almost sessile, they are supported on long footstalks. 
Q. stipularis Humb. et Bonp. Pl. Zquin.,t. 90., and our fig. 1868., Michx. N. Amer. SyL, 1.
