Nevada, but described from specimens collected by Dr. F. A. Wislizenius, 

 on the American River. This beautiful oak commemorates the labors 

 of another early and successful explorer of western America, especially 

 the southern portion of Xew Mexico and Arizona, and in Mexico, where 

 the doctor collected many plants new to science, including a curious 

 genus of the Capar family, named Wislizenia, in his honor. 



8. Quercus Californica. Cooper, 1859. KELLOGG OAK, BLACK 

 OAK. 



This most interesting of the California black oaks is at once dis- 

 tinguished by its very dark, smooth bark (while young), and its large, 

 deeply-lobed leaves, each lobe tipped with a |-inch bristle. With head- 

 quarters in northern California and southern Oregon, where it often 

 attains a height of 80 to 100 feet and a diameter of 2 to 4 feet, this 

 tree ranges from the basin of McKenzie's Eiver, in northern Oregon , 

 southward through the Coast Ranges and along the western slope of the 

 Sierra Nevada, which it ascends 7,000 to 8,000 feet; to the San Ber- 

 nardino Mountains and others of San Diego County, its limit being on 

 the Cuyamaca Mountains. Low, scrubby bushes with small leaves and 

 acorns, not reported hitherto by botanists, were among the first of the 

 discoveries of the writer in Sierra Valley, on the east slope cf the Sierra 

 Nevada, and may be designated as var. transmontana. 



This noble tree was first collected by Hartweg, 1846, near Sonora. 

 Dr. John Torrey referred it, 1856, to Quercus tinctoria, as var. Califor- 

 nica. Dr. J. S. Newberry, deciding it to be a distinct species, named 

 it, 1857, Quercus Kelloggii, in honor of California's pioneer botanist, 

 Dr. Albert Kellogg.* Under the rules of nomenclature demanding that 

 the first applicable name given it must be accepted, Californica must 

 be the specific name of this oak and, incidentally, it was published as 

 Quercus Californica by Dr. Cooper, 1859. However, California bota- 

 nists, hailing with delight the name of Kelloggii, have held to its use 

 until a late date ; while the general public has indelibly fixed the popu- 

 lar English name of this interesting tree as the "Kellogg oak." 



*"Good Dr. Kellogg," as he was called, well deserved this honor, being a true- 

 hearted, industrious, and successful botanist. Coming to California in 1849, he had 

 matchless opportunities in botanical research. With seven others he helped to found 

 the California Academy of Sciences and early became curator of the herbarium, a 

 position held until the time of his death, which occurred 1887, at the age of seventy- 

 four years. He made several botanical excursions up and down the coast, including 

 one to Alaska. Discovering many plants new to science, he had the privilege of 

 naming a marked variety of the Kellogg Oak (Q. Californica, var. Morehtts), three 

 species of ceanothus. three of lily (including the magnificent Lady Washington of 

 the High Sierra), and scores of smaller plants. A Galium-like genus, Kelloggia. found 

 on the mid-Sierra slopes, was dedicated to him by Dr. Torrey, and this with his many 

 botanical papers will preserve the memory of this gentle-spirited lover of nature as 

 long as California plants are collected and studied.
