Diosma cerefolia Vent., Jard. Malmaison 2: tab. 83. 1805. Ξ Agathosma cerefolia (Vent.) Bartl. & H.L.Wendl. Lectotypus (designated here): [ SOUTH AFRICA ]: Hort. Malmaison, Ventenat s.n. ( G [ G00006331 ]!; isolecto-: G-DC [ G00219310 ]!). Notes . – Two specimens of a single gathering have been located: one in Ventenat’s herbarium at G and a fragment in G-DC with the mention “M. B. Delessert 1816”. The later was therefore part of Ventenat’s herbarium before Delessert gave this fragment to Candolle (see introduction). The collection in Ventenat’s herbarium is designated here as the lectotype . Another collection in G-DC [G00219309] originating from Malmaison has been collected after the validation of the name Diosma cerefolia and cannot be considered as original material.
