 Dr. Best gives us here some of the results reached by him in 



the study of the difficult genus Rosa^ after several years research, 



with continued reference to the work of M. Crepin in Belgium. 

 It would be well for botanical science if more of our students 

 would turn their attention to the close investigation of single 



orders or genera, for in this way only can satisfactory results be 



reached, and order brought out of the chaotic condition of 



American systematic botany.

Ficus Sycomorus, Acer Pseudo-platamis and Platanus occiden- 

 talis are the three trees commonly called ''sycamore." The first 

 can claim the title on the score of antiquity, it being the syca- 

 more of the Wo\q; Syco7nonis of the Romans and Sykomoros of 

 the Greeks, from **Sykon/' Fig, and *' Moron," Mulberry. In 

 England the title is applied to the second named, and in our 

 own country the third named monopoHzes it, while throughout 

 Europe it is never applied to Platanus. On the score of priority 

 and etymology we certainly ought to allow Fictis Sycomorus to
