GOLDMAN—PLANT RECORDS OF LOWER CALIFORNIA. 321 
ern slopes of the Victoria Mountains. It formsa tree 6 to 9 metersin height. Flower- 
ing specimens were taken along the road from E] Sacatén to Cape San Lucas, Decem- 
ber 29, and between Miraflores and Rancho San Bernardo, January 20. Brandegee 
records the species from La Purisima and La Paz. 
Salix taxifolia H. B. K. 
This handsome willow, with small, silvery gray leaves, was found sparingly in 
small marshy spots along a stream at about 1,050 meters along the road from Rancho 
San Bernardo to El Satiz on the southern slope of the Victoria Mountains in the Cape 
District. It grows to a height of 10 meters. The new leaves and abundant flowers 
were coming out January 21. 
FAGACEAE. Beech Family. 
Quercus brandegei Goldman, sp. nov. BRANDEGEE OAK. 
Tree 12 to 20 meters high; branches widely spreading, slender, and somewhat 
drooping toward ends; leaves persistent through winter, the blades 40 to 65 mm. 
long, 13 to 18 mm. broad, elliptical, normally acute at apex and cuneate at base, but 
sometimes slightly rounded at one or both ends, usually entire, but occasionally with 
1 to 6 short, irregularly distributed, spiny teeth, short-petioled, glabrous above, 
scurfy or slightly roughened beneath; fruits single or several on peduncles 14 to 34 
mm. long; acorns fusiform, 30 to 37 mm. long, 9 to 10 mm. in diameter, attenuate 
toward the apex, inclosed in a cup for one-fourth or less of their total length; cups 
deeply turbinate, 11 to 13 mm. high, the scales small, acute, grayish-tomentose, 
becoming brownish and appressed at tips. 
Type in the U. 8. National Herbarium, no. 565544, collected at Rancho El Parajfso, 
18 miles southwest of El Triunfo, at northwest base of the Victoria Mountains, Lower 
California, altitude about 540 meters, January 30, 1906, by E. W. Nelson and E. A. 
Goldman (no. 7475). 
This oak evidently belongs to the Q. virginiana group and seems most like Small’s 
Q. fusiformis from Texas. The leaves are very similar, but the acorns present an 
extreme development of the tendency toward elongation and attenuation shown in 
fusiformis. After leaving the San Pedro Martir Mountains we saw no oaks until we 
entered the Victoria Mountains in the Cape District, where three species are appar- 
ently isolated from their congeners to the north by several hundred miles of inter- 
vening desert. Q. brandegei was first noted at about 150 to 450 meters near Mira- 
flores and later at about 540 meters near Rancho E] Paraiso at the northwest base of 
the Victoria Mountains on our way to El Triunfo. It is a handsome species, growing 
scattered along alluvial valley bottoms, the slender, drooping branches in places 
gracefully overhanging the arroyos and roads. At the time of our visit most of the 
acorns had very recently fallen, many of the empty cups still remaining in place. 
The ground under some trees was fairly covered with shell fragments left where small 
rodents had been at work. The species is named for Mr. T. 8. Brandegee, who 
collected flowering specimens at Miraflores, March 21, 1892. 
Quercus idonea Goldman, sp. nov. ENCINO ROBLE. 
Tree 8 to 10 meters high, the branches rather stout, moderately spreading, forming 
a symmetrical rounded top; leaves persistent through winter, the blades 85 to 115 
mm. long, 40 to 50 mm. in greatest width, oblong, acute or slightly obtuse or some- 
what rounded at base, entire or irregularly sinuous and spinescent, with rather short 
tomentose petioles, deep green and shining above, beneath duller and paler, with 
scattered stellate hairs; fruit sessile or with short peduncles; acorns ovoid, rather 
narrow at base, acute at apex, 20 to 25 mm. long, 8 to 10 mm. in diameter, inclosed
