Luehea densiflora Saint-Hilaire (1828: 294) .

Type:— BRAZIL. Minas Gerais: Ouro Preto, “ Vila Rica ”, Saint-Hilaire s.n. (lectotype [as ‘holotype’], first-step designated by Cunha (1985: 17); second-step lectotype, designated here, P! [P 02142937] ; isolectotypes MPU! [MPU017175]; P! [P 02142936]). [= Luehea speciosa Willd.]

Saint-Hilaire (1828) did not mention a particular specimen to describe L. densiflora, and three original specimens collected by him are in P and MPU, both repositories of his collection (Stafleu & Cowan 1976 –1988: 1064). Cunha (1985) indicated a “not seen holotype ” at P, without specifying its identification number. Since two syntypes are present in P, the inadvertent typification by Cunha (1985) can be considered a first-step typification, and it requires now a second-step lectotypification (Art. 9.17 of the ICN). We can now designate herein specimen P 02142937 as the second-step lectotype by choosing the best-preserved specimen in accordance with the protologue’s description. Based on the type materials and original descriptions, the application of the name L. densiflora is confirmed as a heterotypic synonym of L. speciosa, as already accepted by Schumann (1886).
