Sargent, Charles Sprague, Trees and Shrubs. 

 Illustrations of new or little known ligneous 

 plants, pr epared chieily from material at the 

 Arnold Arboretum of Harvard University. Boston 

 and New York (Houghton, Mifflin & Co.) 1902. 



Of the form and general make-up of Sargent's Silva of North 

 America, this occasional publication is intended to deal with new or 

 little known trees and shrubs, the illustrations of which, — drawn by Mr. 

 C. E. Faxon, — are reproduced by photo-mechanical methods, the 

 descriptions being by Professor Sargent and others. Each number, the 

 price of which is Doli. 5.00, net, is intended to contain 25 plates, and 

 each volume will consist of four parts; title page and index appearing 

 with the concluding number. 



New species contained in the first part of Volume I, issued 

 November 26, 1902, are: Crataegus Durobrivensis Sargent, C. Laneyi 

 Sargent, C. Coleae Sargent, C. maloides Sargent, C. luculenta Sargent, 

 C. fruticosa Sargent, C. paludosa Sargent, Faxonanthus Greenman 

 (n. gen.), wich the Single species F. Pringlei Greenman, Ehretia viscosa 

 Fernald, Lonicera saccata Rehder, L. Koehneana Rehder, L. ferruginea 

 Rheder, and L. Arizonica Rehder. 



Unusual features of the first number, which will probably not be 

 repeated in laier numbers, are that Crataegus Durobrivensis was 

 figured and described in a prospectus of the work issued in june 1901 

 and, therefore, as the prospectus was widely distributed, doubtless dates 

 from that time ; and Faxonanthus, based on Mr. P ringle's 8594 oi 

 1901, is published without any indication of its family relationships.

Dans la suite de ses recherches sur les Ochnacees dont 

 nous avons analyse les premieres phases dans ce recueil 

 (XC. p. 363), M. Van Tieghem a distingue encore de 

 nouveaux genres, de teile sorte que le nombre de ceux-ci ä 

 ete porte de 39, d'abord ä 41 (1) puis ä 53 (II). 



Chemin faisant, sont mis en lumiere des faits interessants ä divers
