154 Floristik und Systematik der Phanerogamen. 



lacking, of determining with some approximation to accuracy the known 

 plants of a lange and important region on which at present only scatte- 

 red and most imperfect publications exist, and the more thorough study 

 of which must of necessity be largely dependent upon the critical 

 bringing together of the material now available. At best its publication 

 must extend over a long period of years: but Dr. Britton's energetic 

 and prompt work with his Illustrated Flora gives reason to hope 

 that if properly seconded by his collaborators he may bring the work to 

 a completion during his own lifetime while the provision of an adequate 

 publication fund ensures its uitimate completion in any event. 



The fascicie now issued is of attractive make-up and typography^ 

 and may serve as an Illustration of the general model to be iollowed for 

 the entire work. Fach contributor is given a free band in the treatment 

 of his subject except as to the general limitations incident to approxi- 

 mate uniformity in publication. The subject now dealt with is Rosales 

 (in part). Dr. Small contributes the ordinal description with an analy- 

 tical key to the 24 families that are recognized as constituting the 

 Order. Four of these families are then revised: Podoste/nonaceae (hash), 

 Crassnlaceae (Britton and Rose)^ Penthoraceae (Rydberg), and Paniassia- 

 ceae (Rydberg). 



The method of family treatment is essentially the same as that for 

 Orders, the description being followed by a key to the genera admitted. 

 Generic and specific synonymy appear to be given so far as easential to 

 nomenclature, and under the generic descriptions are given keys to the 

 included species. In addition to the description of each species there is 

 given an indication of „type locality", „distribution and „illustrations" 

 under separate headings.
