Species 1 (v. 2?), Afriez tropicze incola. Typum Candolleanum non vidimus, sed specimina nostra 
juvenilia eongenera nisi conspecifica videntur, etsi herbacea foliis petiolatis. Candolleana verisimi- 
liter magis evoluta erant foliis inferioribus deficientibus. Genus Grangee et, Dichrocephalo valde 
affine, imprimis pappo distinctum. : ;
