tis Zinniae." The first adequate description and publication of the name 

 was in 1887. when Klatt published a careful diagnosis of the Liebmann 

 plant under Zinnia Liebmannii, Benth. & Hook, f., citing Sanvitaliopsis 

 Liebmannii, Schz. Bip., as a synonym. On this description of Klatt the 

 genus Sanvitaliopsis must rest. 



The essential characters of the plant in question "are such that it does 

 not seem to the writer to have been correctly referred to Zinnia where 

 Bentham and Hooker, f., placed it. The narrow attenuated bracts of the 

 involucre, the uncinate-tipped pales, as well as the habit are all greatly at 

 variance with Zinnia ; indeed these differences are so well marked that 

 our only course is to accept Sanvitaliopsis to generic rank, as a member 

 of the subtribe Zinnieae. The recently described Grypocarpha, Greenm., 

 is unquestionably congeneric with Sanvitaliopsis, but represents a second 

 species of the Schultz Bipontinus genus. The complete synonymy with 

 citation of specimens may be given as follows : —
