Luehea paniculata Martius (1826: 100) .

Type:— BRAZIL. Minas Gerais: Mariana, “Habitat in adscensu Montis Itacolumi de Mariana, Aprili”, Martius s.n. (lectotype [as ‘holotype’], first-step designated by Cunha (1985: 25); second-step lectotype, designated here, M! [ M0210164 ] ; isolectotypes K! [ K000381830 ]; M! [ M0210163 ]) .

In the protologue, the specimens on which this name is based are not specifically indicated, but the herbarium of Munich (M) and the Herbarium Zuccarini are repositories of Martius collections ( Martius 1826, Stafleu & Cowan 1976 –1988: 325). The typification claim by Cunha (1985) to be the holotype is corrected here as lectotypification (firststep typification) according to the Art. 9.10 of the ICN. We have found other specimens from the collection of Martius, both in M and other herbaria, with different numbers (263, 265, 269, 609) or s.n., and almost all without indicated locations. Since only location, but no collection number, is noted in the protologue, we accepted only the specimens Martius s.n. as the original material of L. paniculata because they are the only specimens with the location noted. Therefore, in accordance with Arts. 9.3 and 9.4 of the ICN, we designate herein Martius s.n. (M0210164) as a secondstep lectotype, in addition to being the best-preserved specimen and congruent with the protologue’s description. The specimen M0210162 is only a reproduction of Figure 62 from Martius` work. Based on the type materials, the application of the name L. paniculata is confirmed as an accepted species, as proposed by Cunha (1985).
