Jarvis, Charlie, 2007, Chapter 7: Linnaean Plant Names and their Types (part C), Order out of Chaos. Linnaean Plant Types and their Types, London: Linnaean Society of London in association with the Natural History Museum, pp. 370-473 : 442-443

Conyza bifrons Linnaeus , Species Plantarum 2: 861. 1753.

"Habitat in Pyrenaeis, Canada." RCN: 6224.

Lectotype (Pruski in Sida 21: 2032. 2005): Herb. Clifford: 405, Conyza 3 (BM-000647043) .

Current name: Inula bifrons L. ( Asteraceae ).

Note: Although some authors have assumed that Linnaeus (Sp. Pl., ed. 2, 2: 1236. 1763) subsequently transferred C. bifrons to Inula , restricting it to the European taxon, it seems clear that this was not the case. On p. 1207 of the same work, Linnaeus also treated C. bifrons , with the same diagnosis as in 1753 but with only the previously cited Plukenet polynomial in synonymy. The Hermann reference was transferred to the synonymy of I. bifrons , along with three new synonyms. Inula bifrons is evidently a new name in Inula for the European plant (albeit with the same epithet), and not a new combination in Inula of Conyza bifrons . See notes by Godfrey (in J. Elisha Mitchell Sci. Soc. 68: 264. 1952).
