it from Its publication until it was used In the Pflanzenfamilien. 



If the choice had been only between Sorbaria and Basilinia there 



might have been another reason why the former should be pre- 



ferred ; the latter was proposed by the erratic Rafinesque, who did 



things only by halves. But Schi::onotus wdiS proposed by Lindley^ 



one of England's most prominent botanists. Perhaps the fact that 



Rafinesque applied the name Schizonoius to a different genus had 



something to do with it ; but Rafinesque never intended to name 



a new genus Schizonotus^ when he used it as generic name for 



Spiraea discolor Pursh. He simply thought that he was using it in 



the same sense as Lindley. It was simply a matter of wrong 



identification. 



Chamaebatiaria 



This genus has been supposed to be monotypic. There ex- 

 ists, however, a second species, although it seems to be very rare 

 and of a rather restricted distribution. C. MilUfoliinn resembles the 

 genus Chamacbatia in general habit and has often been mistaken for 

 it, bnt this likeness is still greater in Cliamaebatiaria glutinosa. 

 Even to a trained botanist, who knows both, it would be hard, with- 

 out flowers or fruit, to distinguish the latter from CJiamaebatia 

 foiiolosa. The oldest specimen known of C. gliitmosa^ viz., its type, 

 was sent to Dr. John Torrey, who wrote the following remarks on 

 the sheet : '' Given to me by Dr. Bolander, in San Francisco, Sept., 

 1872. The only specimen he had ever seen. We both supposed it 



Millefolium. 4-5 feet high."

PORTERANTHUS 



This genus was first published under the name of Gillenia 

 Moench in 1802. There is, however, an older (7//A7/^ Adans.* 

 named for the same person and properly published, as it was 

 based on Volkameria P. Br.f and Timis L.J
