58 THE AMERICAN MIDLAND NATURALIST 



TESSENIA Bubani, Nfuov. Giorn. Bot. It. V: 318 (1873), 

 also PI. Pyr. 2: 263. (1900). Name in honor of Tcssen, a Chinese 

 emperor who in 1200 A. C. had a splendid botanical garden. If 

 Tessen the botanist deserved to be honored the name is just as 

 good, as it would be bad' if dedicated to the imperial Mecenas. 

 Botanical work and research, not material gifts, should inspire 

 a name.
