tically every species is illustrated in a most satisfactory manner, 

 to show not only the spore-forms, but in many instances the gross 

 appearance of the fungus and the distortions it produces as 



well. 



Preceding the systematic part twenty chapters are devoted to 

 a discussion of the general subject of rusts in its various aspects, 

 and from the most modern points of view. It is by much the 

 best account now available in the English language. 



Following the systematic account is a glossary, bibliography, 

 and three ample indexes. Nothing has been forgotten that might 

 make the work serviceable and complete. 



The thoroughness with which the author has accomplished 

 his task, the culmination of many ye?rs of observation and study, 

 has insured a valuable work of reference for both local and other 

 botanists. But even more than this, the broad spirit in which 

 the work has been conceived, and the ability shown to discover 

 and interpret the less obvious morphological structures, give 

 added value to the record of facts. The author states that there 

 was "a special object in view in thus recording and describing 

 the rust-fungi of Australia, for this can afterwards be used as a 

 basis in working out the life-history of those particular fornis 

 which attack our cultivated and economic plants," which is 

 clearly a sensible method of procedure in attacking the difificult 

 problem of the harmful rusts. It was the author, who a short 

 time ago established the interesting genus Uromycladium with 

 its half dozen or more species, founded upon heretofore unrecog- 

 nized fruiting structures, and his perspicacity brought to light the 

 fascicled arrangement of teliospores in the plum and peach rust, 

 which has put a new interpretation upon the affinities of this 

 and similar rusts. It is this clear insight, and the accuracy and 

 fullness of details, that commend the work to all students of the 

 rusts in every part of the world.
