2-celled. Female flowers axillary, nearly solitary, sessile or on very short stalks. Scales of the cup 
roundish, covery with powdery down. Ovary globose. Styles2. A native of the mountains of 
Mexico, in moist shady situations, and frequent near Moran, an elevation of 18,000 ft. (3000 
toises) ; where it covers whole hills. It is remarkable for its small size, evergreen leaves, and long 
downy catkins of male flowers. Humbolt called it Q. depréssa, because its branches are always 
close to the ground.

p. 111. Leaves oblong-oboval, 
wavy; obtuse at the base; 
reticulately veined beneath, 
somewhat hairy. Female 
spike pedunculated. (Humb. 
et Bonp.) A tree, 40 ft. high. 
Branches and twigs round, 
glabrous. Leaves 3in. long, 
on short footstalks, somewhat 
membranaceous; sometimes 
emarginate; glabrous and 
shining above, green and 
downy beneath. Spikes of fe- 
male flowers axillary, often 
twin, on long stalks, 5—6- 
flowered. Flowers downy. A 
native of Mexico, near Moran, 
at an elevation of above 9000 
ft. (1500 toises.) It is closely 
allied to’ Q. elliptica Nee. (See p. 1918.) It differs very little 
from Q. elliptica Nee, and Q. spicata Humb. et Bonp., but its 
leaves ‘are narrower towards their lower extremity, slightly 
sinuated on the margin, glaucous, and always reticulately 1873 
veined and hairy beneath; and the spikes of female flowers 
are generally axillary, and in pairs. ur readers must not confound this Q. ambigua with the one 
in cultivation in British gardens, described p. 1881. Doubtless, this plant, as having had the name 
applied to it after the other, will receive an unappropriated name from some botanist who may 
revise the genus. 
Q. confertifilia Humb. et Bonp, Pl. quin., t.94., and our fig. 1872., Michx. N. Amer. Syl., 1. 
p. 106. aves evergreen, linear-lanceolate, mucronated, recurved at the margin, quite entire ; 
downy beneath. Fruit sessile. (Humb. et Bonp.) An evergreen shrub, from 15ft. to 20 ft. high. 
Branches short, crowded, and leafy. Leaves 3 in. long, on short stalks, somewhat leathery ; obtuse at 
the base, surrounded with a cartilaginous recurved line; glabrous and shining above, downy and 
transversely veined beneath. Fruit sessile on the branches below the leaves, often twin. Scales of 
the cup oval, closely imbricated, membranaceous. A native of the temperate and mountainous 
regions of New Spain, between the town of Guanajuata and Santa Rosa. This evergreen shrub, or 
low tree, would be a great ornament to our gardens, where it would form constantly green and thick 
masses of foliage ; and, from the temperate and mountainous climate of which it is a native, it would 
probably stand in the open air perfectly well in the climate of London. 
Q. tridens Humb. et Bonp. Pl. Hquin., t.96., and our jig. 1873., Michx. N. Amer. Syl, 1. p. 107. 
Leaves oblong, retuse at the base, generally broader towards the apex, 3-dentate; teeth terminated 
by bristly points; downy beneath. Spikes of female flowers almost sessile. (Humb. et Bonp.) A 
shrub, ut 10 ft. high, with round smooth branches. Stipules deciduous, narrow, linear. aves 
about lin. long, membranaceous ; 
downy and slightly tomentose beneath, 
covered with stellate down above, some- 
times entire ; narrowed towards the base. 
Male flower: calyx 6—7-parted,  sta- 
mens 8. Spikes of female flowers axil- 
ary, almost sessile, 3—5-flowered. A 
native of New Spain, and common in the 
vicinity of Moran. The name Q. tridens 
has been applied to this species, from 
the circumstance of the leaves being al- 
most constantly furnished with 3 teeth at 
the apex, although otherwise entire. It 
is found at an elevation of 7800 ft. (1300 
toises.) F. A, Michaux mentions that it 
is sometimes found 20 ft. high.

and valuable tree, with a trunk about the 
thickness of a man’s body, covered with 
cracked bark. Leaves on longish foot- 
stalks, blunt; somewhat lobed at the 
base; glabrous above; covered beneath 
with brown woolly tomentum ; 5 in. to 6in.
