Further notes on the typification of some species in Indigofera (Fabaceae)

The typification of the names of three non-endemic species of Indigofera in Australia is revisited. Firstly, the uncertain typification of an introduced species, I. hochstetteri Baker, is considered; a previous, imprecise lectotypification is recognised and a second step lectotype is designated. Secondly, an earlier error in the citation of the type of another introduced species, I. sessiliflora DC., is corrected and specific details of the holotype are provided. Thirdly, a lectotype is designated for I. seticulosa Harv. a synonym of the widespread native species, I. colutea (Burm.f.) Merr.
