THE GENERIC NAME SCHIZONOTUS. 



Br T. A. Spbague, B.Sc., F.L.S. 



The name Schizonotus has been used for two genera of Rosacea? 

 and one of Ascle-piadaceee. Schizonotus Lindl. (1S30) is Sorbaria 

 A Br. (18G4), a nomen conservandum under the International Rules 

 of Nomenclature. Schizonotus Rafin. (1836) is llolodiscus Maxim. 

 (1879), which is also a nomen conservandum. Schizonotus A. Gray 

 (1876)' is equivalent to Solanoa Greene (1890), and Solanoana Kuntze 

 (1891). As the citations in the Index Kewensis of Schizonotus 

 Lindl. and Schizonotus Rafin. are not as complete as might be 

 desired, the references and synonymy of the three genera are now
