Van Ooststroom (Dlumea 3: 286. 1936) adopts Sh'utereia Choisy (1833) in- 

 stead of Hewittia (1837), calling our plant Shutereia sublobata (L.f.) House. 

 Sbuteria Wight & Arn. (Leguminosae) is conserved against Shutereia Choisy. If 

 Shutereia and Shuteria are considered different names, then van Ooststroom is 

 right, if as orthographic variants, then Hewittia must be retained; which course 

 is taken depends on the interpretation of Article 82 of the International Code. 

 The examples illustrating this rule, in me at least, merely cause a state of con- 

 fusion. The implication of conserving Shuteria against Shutereia is evidently 

 that these are to be considered orthographic variants, and I therefore use Hewittia 

 instead of following van Ooststroom. 



I am indebted to the Librarian of the Linnean Society of London for kindly 

 checking for me with the original the Wight and Arnott references.
