46 WEST AMERICAN OAKS. 



Q. DuNNii, Kellogg, Pacif. Rural Press, (7 June, 1879): Q. Pa/meri, Engelm., Bot. 

 Calif, ii. 97 (Oct., 1879). An evergreen White Oak of the northern part of the Lower Cal- 

 ifornian peninsula, doubtless is also to be found north of the U. S. boundary: foliage much 

 like that of some forms of Q. chrysolepis^ but the habit different: the species particularly 

 well marked by erect aments and turbinate thin cups; both leaves and cups fulvous-lepi- 

 dote. 



Dr. Kellogg's name for the species one is bound to adopt; for it has priority, although 

 by four months only, over that proposed by Dr. Engelmann. 



Q. SadlERIANA, R. Brown Carapst., Ann. & Mag. Nat. Hist. vii. 249 (1871); S. Wats., 

 Proc. Am. Acad. xxii. 477. A deciduous White Oak bush of the mountains of Oregon 

 and northern California: leaves oblong-obovate, acute, cuneate at base, pinnate-veined and 

 coarsely and sharply toothed; fructification annual: acorns sessile; cup shallow, tubercu- 

 late; nut oblong, obtuse, less than an inch long. 



The species is a comparatively new and interesting one. Mr. Howell, the well known 

 Oregon botanist has twice collected it since it was discovered by Mr. Brown in 1865; but it 

 seems not to be common. 



Q. Jacobi, R. Brown Campst. 1. c, of Vancouver Island is even less known than the 

 last. It has passed for Q. Garryana^ according to Mr. Watson, who thinks it may be dis- 

 tinct. It should be investigated carefully by our friends of the northern coast.
