ascenclentes, distanter bracteati, apice oligocephali (raro monoce- 

 phali), + 4 cm. long. Bracteae ex axi ortse pleraeque 1-5-2 cm. 

 long., 5 mm. lat., margine denticulatge ; bracteae ramulorum

Near V. Quartiniana A. Eich., but, among other features, the 

 foliage and capitula of the two are very unlike.

Allied to V. cardiolepis 0. Hoffm. and V. Britteniana Hiern, 

 but differing from both in foliage and in the short crowded 

 inflorescences. The sparsely hairy involucres with acuminate 

 appendages are also good points by which it can be distinguished 

 from the latter, while the involucral leaves of F. cardiolepis, besides 

 having a rotundate appendage, are much narrower.
