822 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
in cups for about one-third their total length; involucres deep cup-shaped, 9 to 11 
mm. high, the scales hoary-tomentose, roughened or tuberculate on outer surface. 
Type in the U. 8. National Herbarium, no. 565500, collected near Rancho San 
Bernardo, 13 miles west of Miraflores on the eastern slope of Victoria Mountains, 
Lower California, altitude about 600 meters, January 20, 1906, by E. W. Nelson and 
E. A. Goldman (no. 7423). 
This oak is similar to Quercus glaucoides Mart. & Gal., from Oaxaca, but the acorns 
are more elongate, the cup scales thicker, more tuberculate, and less acuminate at the 
tips; the leaves have longer, more densely tomentose petioles (leaves nearly sessile and 
smooth in glaucoides), and their lower surfaces are stellate-hairy (glabrous in glaucoides). 
On the lower slopes of the Victoria Mountains, mainly on the east side, this oak 
grows abundantly and is generally distributed at about 600 to 900 meters altitude. 
It is overlapped by the “‘encino negro” (Q. devia), which gradually becomes the 
dominant species, especially on north slopes, and replaces it entirely in the Upper 
Sonoran Zone above about 1,500 meters on the south side of the Sierra de la Laguna. 
At the time of our visit the ripe acorns had recently fallen in abundance, but a few 
still remained in the cups. 
Quercus devia Goldman, sp. nov. ENCINO NEGRO. 
Tree 20 meters high, the branches mainly upright and tending to forma cone-shaped 
top; leaves persistent through winter, the blades 60 to 100 mm. long, 15 to 31 mm. 
broad, elliptical, acute or cuspidate at apex, usually rounded or cordate at base, 
entire for one-third to one-half their length, becoming sinuate-dentate, with slender, 
rigid spinose points along terminal portion, short-petioled, thinly pubescent with 
scattered short stellate hairs and bearing longer tufts of stellate pubescence on mid- 
rib near base and in angle between midrib and revolute margin; acorns small, 15 to 
17 mm. long, 7.6 to 8.4 mm. in diameter, rather narrow and rounded at base, tapering 
and acute at apex, set in shallow cups for less than one-fourth their length; cups 
saucer-shaped, about 4.5 mm. high, the scales thin, acute, grayish-tomentose, margined 
with reddish brown. 
Type in the U.S. National Herbarium, no. 565525, collected near La Chuparosa, a 
spring at about 1,500 meters altitude in the Sierra de la Laguna, Lower California, 
January 23, 1906, by E. W. Nelson and E. A. Goldman (no. 7454). 
The leaves of this species superficially resemble those of Quercus acutifolia Née, 
but are shorter petioled, the blades more rounded and wedge-shaped at the base, 
with pubescence less generally distributed over the lower surface. The fruit some- 
what resembles that of Q. phellos, but the acorns are larger, more slender, and less 
expanded near the base, and the leaves are so widely different that the two are evi- 
dently not closely allied. Q. devia ranges upward from about 1,050 meters on the 
south slope of the mountains to the summits at about 1,800 meters, where it is one of 
the few species that characterize the Upper Sonoran Zone. It is associated with 
Q. idonea below about 1,500 meters, but replaces the latter entirely above this 
elevation. Its native name is “‘encino negro.”’ 
Quercus agrifolia Née. CALIFORNIA LIVE OAK. 
The California live oak ranges southward into the Peninsula through the Upper 
Sonoran foothill region between the Pacific coast and the western slopes of the high 
mountains, It was noted mainly along arroyos and canyons in a number of localities | 
from near Ensenada northward to the Valley of Guadalupe along the road to Tijuana 
and eastward to La Huerta at the western base of the Sierra del Pinal. It was abun- 
dant also along small arroyos at about 1,110 meters altitude near El Alamo and between 
La Posaand Rancho Viejo. The largest trees were seen along the river at San Antonio, 
where at about 900 meters elevation a permanent stream emerges from the west slope 
of the San Pedro Martir Mountains. Oaks supposed to be of this species were noted
