Conyza Less., Syn. Gen. Comp. : 203 (1832), nom. cons.
Conyzella Fabric., Enum.: 86 (1759). Type: not stated.
Marsea Adans., Fam. 2: 122 (1763). Type: not stated.
Eschenbachia Moench, Meth.: 573 (1794). Type: Eschenbachia globosa Moench = Conyza aegyptica (L.) Ait.
Dimorphanthes Cass., Bull. Sci. Soc. Philom. Paris 1818: 30 (1818). Type: not originally stated as no valid
combinations of the species transferred from Erigeron were made. Lectotype (designated by Nesom, 1990:
231): Dimorphanthes aegyptica (L.) Cass. = Conyza aegyptica (L.) Ait.
Fimbrillaria Cass., Bull. Sci. Soc. Philom. Paris 1818: 30 (1818). Type: not stated, but based on Baccharis ivifolia

Leptilon Raf., Amer. Monthly Mag. : 268 (1818), nom. nud. (based on Erigeron divaricatum Michx.)
Erigeron L. sect. Caenotus Nutt., Gen. Pl. 2: 148 (1818). Type: not cited.
Edemias Raf., Fl. Tellur. 2: 49 (1836). Type: not cited. Lectotype (designated by Nesom, 1990: 232): Conyza
aegyptica (L.) Ait.
Astradelphus Remy, Ann. Sci. Nat. Bot., ser. 3, 12: 185 (1849). Type: not stated. Note: the combination
Astradelphus chilensis Remy is ascribed to this place but no such description or combinatioon was made,
and certainly no such epithet was combined with the generic name. Although the binomial appears in
Index Kewensis 1(1): 226 (1893) it was in italics and therefore not accepted there.

Type: Conyza chilensis Spreng. = Conyza primulifolia (Lam.) Cuatrec. & Lourteig

Note: Foster (1958: 207) recorded E. floribundus, as well as E. bonariensis. Some authors would consider that
Conyza floribunda is a synonym of C. bonariensis.The synonymy may well be augmented if Cabrera (1978) is
followed. There was obviously some disagreement between Cuatrecasas (1969) and Cabrera (1978) over the
