dentatis v. minutim denticulatis v. passim breviter lobatis, capitulis 
parvis in paniculas terminales et laterales subcorymbosas congestis, 
masculis campaniformibus, femineis subgloboso-urceolaribus, co- 
rollis albidis, acheniis minutis glabris. 
Genus seriei Grangearum adnumeravi; a Dichrocephala differt 
propter involucrum imbricatum et pappum masculum non abbre- 
viatum, sicut sexus distributionem et achenii formationem.  At- 
tingit etiam ad Epaltem, quz perfecto pappi defectu, floribus mo- 
noicis et acheniis obovato-ellipsoideis nec obliquis nee lineola 
notatis discernitur. Ab Ethulia longius distat, ut e planta imper- 
fecta jam przeclarus Hooker suspicabatur.
