Quercus I2 53 



oak at Santa Barbara to repair his ship the Discovery. The Indians used to con- 

 sume the acorns for food, preferring them to those of any other oak. 



This species was introduced by Hartweg in 1849, when a few miserable living 

 plants, sent home by him, were reported 1 to be growing in the Horticultural Society's 

 Garden at Chiswick. As I can find no further allusion to this species, I suppose 

 that these are the trees which we have found growing in two places in England, and 

 which seem of similar age, namely, at Kew, where it has now attained a height of 

 30 ft. ; and at Killerton, where there are two trees above the house close to the 

 deer-park fence. In 1908 the best of these measured 45 ft. by 7 ft., and forks at 6 ft. 

 from the ground. On April 18, it was budding, and the old leaves were still green. 

 At Tortworth there is a small tree which seems to be younger, and was probably 

 raised in 1878 from American acorns at the same time as Q. Kelloggii.

QUERCUS WISLIZENI 



Quercus Wislizeni, A. de Candolle, Prod. xvi. 2, p. 67 (1864); Sargent, Silva N. Atner. viii. 119, 



t. 406 (1895), and Trees N. Amer. 253 (1905). 

 Quercus parvula, Greene, Pittonia, i. 40 (1887). 



A tree or shrub, similar to Q. agrifolia in habit, size, and bark. Young 

 branchlets with scattered stellate pubescence. Leaves (Plate 338, Fig. 58) de- 

 ciduous in the second year, variable in shape and size, mostly oblong-lanceolate, 

 averaging 1^ in. long and f in. wide, coriaceous, acute at the apex, broad and rounded 

 or truncate at the base, with 9 to 13 spine-tipped teeth in the wrinkled margin, 

 which in rare cases is entire ; both surfaces shining, glabrous, with a conspicuous 

 network of fine veinlets ; petiole \ in. long, stellate-pubescent. 



Fruit ripening in the second year, sessile or stalked ; acorns ovoid, about 1 in. 

 long, acute at the apex, enclosed to a variable height in a turbinate or tubular 

 cupule, slightly pubescent within, and covered by thin lanceolate pubescent scales. 



This species, in the absence of fruit, is with difficulty distinguishable from 

 Q. cocci/era, which has, however, foliage of a lighter tint of green. The buds in 

 Q. Wislizeni are long, spindle-shaped, and pointed at the apex ; while those of 

 Q. coccifera are smaller, ovoid, and obtuse. 



Q. Wislizeni, which is closely related to Q. agrifolia, is widely spread through- 

 out California, and is also found on the San Pedro Martir mountain in Lower 

 California. It is most abundant and of its largest size in the valleys of the coast 

 range of central California and on the foothills of the Sierra Nevada. It is common 

 in a shrubby form in the canons of the desert slopes of the mountains in the 

 southern part of the state. 



Introduced into Kew by Mr. H. N. Bolander, who sent acorns in 1874, it was 

 only 65 ft. high in 1897, Dut f ^ ate years is more thriving, and now forms a bushy 

 tree about 15 ft. in height. We have seen no specimens in cultivation elsewhere.
