124 THE AMERICAN BOTANIST 



More advanced students — say those who have had a course in 

 high school botany would find such a book as Arthur and 

 MacDougal's "Living Plants and their Properties" ($1.35) 

 desirable. Other books for special subjects would be Bailey's 

 "Plant Breeding" ($1.25), Grant Allen's "Colors of Flowers" 

 ($1.00) or Henslow's "Origin of Floral Structures" ($2.00). 

 We cannot too strongly urge upon the plant collector that real 

 botany is more than the preserving and naming of plants. 

 Many very intelligent people amass large herbariums and be- 

 come familiar with every species in their region without sus- 

 pecting that there is a vast and unexplored field of the great- 

 est botanical interest close at hand that needs only a proper 

 introduction to be as fascinating as ever plant collecting and 

 naming could be. This is the time of year when clubs of the 

 kind we have mentioned are most easily formed. Those who 

 have tried without success to get their friends actively inter- 

 ested in botanical studies should try the merits of such a club. 

 We shall be glad to send a copy of this magazine free to every 

 club of four or more members organized after this plan and 

 will continue to send the magazine as long as we receive 

 quarterly reports from the club regarding its work. We hope 

 that all who are tired of studying botany alone will go to work 

 at once to organize a club. 



BOOKS AND WRITERS 



That there are more than fifty thousand different species 

 of fungi in the world is not hard to realize after a look through 

 Prof. F, E. Clements' "Genera of Fungi," in fact it is this vast 

 number of fungi that make such a book either necessary or 

 possible. For many years the descriptions of the plants be- 

 longing to this great group have been accumulating in the 

 various volumes of Saccardo's "Sylloge Fungorum" but in 

 this form were almost inaccessible to students. The present 

 book is designed to key out the genera and families of Sac-
