154 PACIFIC STATES FLORAL CONGRESS. 



before the Academy of Sciences at St. Louis, Mo., by Dr. Geo. Engel- 

 mann, described forty species, including nine more western ones. In 1880 

 Dr. Engelmann elaborated the genus Quercus, the oaks, in Watson's 

 second volume of "Botany of California." It included descriptions of 

 eleven western species. No illustrations accompanied cither of these 

 papers. 



"Forest Trees of California" appeared 1882, published by Dr. A. 

 Kellogg, one of the seven founders of the California Academy of Sci- 

 ences. It includes seven species of oak, lovingly described by the 

 doctor in appreciative but non-scientific language, interspersed with 

 poetical quotations. For many years afterward, Dr. Kellogg devoted 

 odd hours to accurate drawings of oak branchlets the foliage, flowers, 

 and fruit which were utilized by a later author. 



"West American Oaks," appearing 1889, is a folio volume in two 

 parts, by Prof. E. L. Greene, then of the University of California. 

 The first part is a memorial tribute to the labor and worth of Dr. 

 Kellogg, the illustrations being those cited above as the painstaking work 

 of the doctor. The species, seventeen in number, include Quercus Morc- 

 lius, of Kellogg, and a new and tenable species described under the 

 name of Q. Engelmanni. 



Dr. Kellogg's drawings of species outside of California were made 

 from specimens collected in Arizona and New Mexico by the writer, 

 as noted by the pencil of Dr. Kellogg and the pen of Professor Greene. 

 The second part presented several proposed new species, illustrated by 

 drawings by Geo. Hanson. 



"Forest Trees of North America," being vol. 9 of the Tenth Cen- 

 sus of the United States, appeared 1884, by Prof. C. S. Sargent, 

 director of. Arnold Arboretum. This large folio volume contains 

 extended discussions of trees from many points of view, describing 

 forty-eight oaks, sixteen of them inhabiting West America. No illus- 

 trations. 



"Arborescent Flora of the United States" is the title of a classified 

 list or bulletin from the Agricultural Department at Washington, 

 issued 1887, by Geo. B. Sudworth, dendrologist of the Division of 

 Forestry. The publication of this painstaking list gave Mr. Sudworth 

 the opportunity to apply the new rules of priority in the presentation of 

 names, whereby he becomes the author of scores of new designations 

 of well-known trees, including Sequoia Wasliingtoniann, for our Giant 

 Sequoia. 



This volume was followed, 1898, by a Check List of United States 

 Forest Trees, their Names and Eanges, including seventeen species 

 of oak from West America.
