Type:— BRAZIL . Minas Gerais : Minas Novas , “Habitat inter arbores ad margines fluviorum ad Rio S.Francisco , Capitanae Minas Novas. Legi florentem mense Octobri 1819”, Pohl s.n. ( lectotype [as ‘holotype’], first-step designated by Cunha (1985: 10) ; second-step lectotype, designated here , W! [ W0071087 ]) . Minas Gerais : Minas Novas , Pohl s.n. ( syntype remaining W! [ W0071386 ]). [= Luehea candicans Mart. ] Pohl’s original collection is kept in W where he worked and lived ( Stafleu & Cowan 1976 –1988: 315), and where we found only two specimens reported by the author to the name L. microphylla and collected by him in Brazil ( B. Wallnöfer , pers. comm.). These two specimens are syntypes of L. microphylla , and the previous typification of Cunha (1985) needs to be corrected ( Art. 9.2 of the ICN), since it represents the first-step lectotype of L. microphylla and now requires the second-step typification by the way of subsequent lectotypification ( Art. 9.17 of the ICN). For this reason, we designated herein the specimen Pohl s.n. (W0071087) the second-step lectotype of L. microphylla , that agree well with the morphological description presented in the protologue. Based on the type materials, the application of the name L. microphylla Pohl is confirmed as a heterotypic synonym of L. candicans , as previously accepted by Cunha (1985).
