Wesi American Oaks, Edward L. Greene. (Pamph.; 4 to.; pp. 

 46; twenty-four plates ; San Francisco, May, 1889.) 

 The late Dr. Albert Kellogg left many papers and drawings, 

 representing his studies of West American botany. Among 

 these were a number of drawings of oaks — almost all in fact which 

 are known in California and adjoining territory at the present 

 time. Dr. Kellogg .died without completing the descriptions 

 which were to accompany them, but his friends W. G. W. Har- 

 ford, W. P. Gibbons and Justin P. Moore determined that his 

 labors should not be lost to science. They secured the coopera- 

 tion of Prof Geo. Davidson, in response to whose appeal Prof. 

 Edward L. Greene agreed to write the text and Mr, James M. 

 MacDonald undertook to bear the entire expense of publication. 

 The result is the splendid monograph before us, which is not 

 only a credit to all concerned in its issue, but is a lasting monu- 

 ment to the memory and labors of Dr. Kellogg- The plates are 

 perfect, both in design and execution, leaving nothing further to 

 be desired from them. The monograph is preceded by the cor- 

 respondence with Mn MacDonald, a sketch of Dr. Kellogg's life 



w 



and works by Prof. Davidson, and an introduction to the subject 

 by Prof. Greene. In addition to the eighteen species and varieties 

 figured by Dr. Kellogg, the text contains descriptions of two new 

 species, Q. MacDonaldi and Q. turbinella. One new variety, Q, 

 dumosa, Nutt, var. mimita, is figured and described, and another, 

 Q. Engelmanni, Greene, var. elegantida, is briefly menlioned. 

 Q. Engelmanni is a new species, which was drawn by Dr.

Kello.£fg under the impression that it was a form of Q 

 ^folia, Torr. A hst of six others occurring in the region, but 

 not figured, is appended for the purpose of making the work as 

 complete as possible. In his arrangement of the species Prof. 

 Greene has adopted the unconventional system of placing the 

 Black Oak group first, for the reason, as he frankly intimates, that 

 this allows him to begin the work with Q. Kelloggi, Newb., fol- 



7 Q. Morehus, Kellogg. Having thus adopted the un-

 " Quercus densiflora is, indeed, almost as much a Chestnut as it 

 'S an Oak ; but, as an Oak, it is obviously of that group in which
