≡ [after typification] Cytisus triflorus L’Hér., non Lam., nom. illeg.

Type

(neotype, here designated): Algeria. In montibus prope Algeriam, s.d., R. L. Desfontaines, s.n. (G 00007761 [digital photo!] image: https://www.ville-ge.ch/musinfo/bd/cjb/chg/adetail.php?id=30955).

Note.

We did not find any original material for this name either in MAF (MAF-Pourret collection), and P (the general collection and the special Pourret’s collection named " Chloris narbonensis "), where Pierre André Pourret’s (1754-1818) collections are mainly kept ( Stafleu and Cowan 1983), or in other relevant herbaria (BM, FI, MPU, and UPS; see Stafleu and Cowan 1983: 368). It seems, therefore, that the original material for this name is lost. This possibility is not surprising giving Pourret’s dramatic escape from France to Spain in 1789 and his forced exile ( Galibert 1856), followed by several war events ( Stafleu and Cowan 1983: 368). Because the original material of C. villosus is lost, we have decided to choose a neotype represented by the specimen G00007761 housed at G-DC. This specimen has been previously selected by Cristofolini and Fumeaux (Cristofolini and Troia 2006) as the lectotype of C. triflorus L’Hér. [1791]; an illegitimate name (a later homonym of C. triflorus Lam. [1786]) being conspecific with C. villosus Pourr. (see Polhill 1978; Cristofolini and Troia 2006). Importantly, as Cytisus triflorus L’Hér. has been accepted as the conserved type for the generic name Cytisus Desf., nom. cons. (Appendix III of the ICN), it becomes automatically a homotypic synonym of Cytisus villosus Pourr. - which is the accepted name of the generitype of this genus.
