IV. Diagnoses and Synonymy of Eijpatorieae and of certain 



OTHER CoMPOSITAE •WHICH HAVE BEEN CLASSED WITH THEM. 



Apodocephala Balv. Jour. Linn. Soc. xxi. 417 (1885); S. Ell. ibid, 

 xxix. 28 (1891); Hoffm. in Engl. & Prantl Nat. Pflanzenf iv. Ab. 5, 

 134, 135 (1890), 388 (1894). Through the courtesy of Sir William 

 Thiselton Dyer and Dr. Stapf of the Royal Gardens at Kew the 

 writer was permitted to make dissections of the flowers of both species 

 of this problematic genus of Madagascar, which has been referred to 

 the Eupatorkae by Mr. Baker and to the Vernon ieae by Dr. Hoffmann. 

 The anthers are clearly sagittate, the leaves alternate, the style- 

 branches rather strongly recurved and acutish, and the involucre of a 

 form and texture far more frequent in the Vernonieae than in the 

 Eupatorkae. Indeed, all features observed seem to confirm fully the 

 view of Dr. Hoffmann that the genus should be referred to the former 

 tribe.
