[Tropicos] Notes from Flann et al. 2010 Taxon 59: Type - Erigeron aegyptiacus (‘ægyptiacum’) L. (Eschenbachia globosa Moench, nom. illeg., D. aegyptiaca (L.) Cass. in Cuvier , Dict. Sci. Nat. 13: 255 1819, Conyza aegyptiaca (L.) Aiton) Notes: In the protologue of Dimorphanthes, Cassini includes various Erigeron species in that genus, four of which he mentions by name. In App. III of the ICBN, Dimorphanthes is listed as not yet typified, but this is a double error. Firstly, Cassini when formally transferring Erigeron siculus L. to Dimorphanthes as D. sicula (L.) Cass. (in Cuvier, Dict. Sci. Nat. 13: 255 1819), designated it as the type (‘on doit la considérer comme le type d’un nouveau genre’). Secondly, as already noted in ING, one of the four binomials listed in the protologue is Erigeron aegyptiacus, which provides the type of the earlier, legitimate name Eschenbachia. The consequence is that Cassini’s subsequent type designation becomes irrelevant, because Dimorphanthes is automatically typified (ICBN, Art. 7.5). It should be removed editorially from App. III of the Code, where Eschenbachia is already listed as rejected. Whereas in the relevant literature the combination Conyza aegyptiaca (L.) Aiton is still in use, according to Richard Noyes (pers. comm.) the species does not belong to the Erigeron-Conyza complex, so that the name Eschenbachia may eventually be revived.
