Fontella & Goyder , comb. nov. Basionym : Cynanchum odoratum Hooker & Arnott (1834: 294) . Type : ARGENTINA . ‘ Old dykes near Buenos Aires’ , no date, J . Tweedie s.n. ( holotype K !, possible isotypes BM !, K !) . = Morrenia intermedia Meyer (1950: 51) . Type : ARGENTINA . San Luis : Pedra Blanca , Departamento Junín , 12 February 1948 , T. Meyer 13845 ( lectotype (here designated) LIL-barcode LIL001169 !). Synon. nov. Note :— Goyder (2003: 716) suggested M. intermedia might be a hybrid between M. odorata and M. brachystephana , based on the comments made by Meyer (1950) . However, he had at the time not seen the type. Having now examined type material at LIL , we are able to resolve the identity of this plant. There are two sheets with the number Meyer 13845 housed at LIL , one with a flowering specimen, which matches the description of M. odorata , and a fruiting specimen, which does not. We have chosen the sheet with the flowering specimen as lectotype to fix the application of this name.
