A15STRACT — DC, Application of the names Eugenia maritima DC. unAMyrcia polyantha discussed — is these were proposed twice by de Candolle in the same pubhcation and vahdation provided for is the names involved: Eugenia lihensis O. Berg, Eugenia maritima (Kunth) DC. (interpreted here as the & correct name for E. acapulcensis), Myrcia neopolyantha Sobral Mazine, nom. nov. (a andM replacement name ^or Myrcia polyantha DC), splendens (Sw.) DC. Comments are provided M for additional varieties of polyantha. Eugenia maritima andMyrcia polyantha were proposed twice by de Candolle in his treatment of Myrtaceae for the Prodromus (1828). In both cases, these names were proposed for a new species and for a combination based on a preexisting name. Since then, authors have either considered some of these names valid or merged them in the synonymy of other species (Berg 1855-1856; Steudel 1840; McVaugh 1963; Govaerts et al. 2015); nevertheless, some of these usages are not in accordance we we with current nomenclatural rules. Here discuss these names and propose what consider their correct application according to International Code of Nomenclature for Algae, Fungi and Plants (ICN- McNeill etal. 2011). EUGENIA MARITIMA 1. Eugenia maritima DC. was proposed for a Brazilian species by de Candolle (1828: 271), while Eugenia maritima (Kunth) DC. (1828: 282) was based on the MexicanMyrte maritima Kunth (1823). The Brazilian species was previously undescribed, while the Mexican species was a new ICN combination based on a preexisting name. Article 11.4 of (McNeill et al. 2011) states that "the correct name for one taxon below the rank of genus the combination of the final epithet of the is earhest legitimate name of the taxon in the same rank, with the correct name of the genus or species DC, to which assigned," implying that Eugenia maritima (Kunth) based onMyrtus maritima, the it is DC, earliest legitimate name, has priority over Eugenia maritima which was correctly renamed by Berg (1856) as Eugenia ilhensis.

Bot. ed. 2, 1: 601. 1840, nom. illeg., replacement name for Eugenia maritima (Kunth) DC. This species widely variable and has been extensively discussed under Eugenia is (seeMcVaugh acapuicensis 1963: 421). MYRCIA POLYANTHA 2. This name was used both for the Bmzilian Myrcia polyantha DC. (1828: 252), a new species, DC, new mMyrtus and the Venezuelan Myrc/t? polyantha (Kunth) (1828: 255) a combination based ICN polyantha Kunth (1823: 140). The application of Article 11.4 of (McNeill et al. 2011, see above DC, under Eugenia maritima) states that Myrcia polyantha (Kunth) based on the preexisting legitimate name Myrtus polyantha, vahd over M. polyantha DC. The Kunthian species a is is synonym of Myrcia splendens (Sw.) DC. (Govaerts et al. 2015), vihile Myrcia polyantha DC. is a vahd eastern Brazilian species in need of a replacement name. Berg (1857-1859), in his treatment of Brazilian Myrtaceae, considered Myrcra polyantha under his genus Aulomyrcia O. Berg (Berg 1855- 1856: 35), under which he proposed three varieties, two of which belong to other species and are properly synonymized below. MYRCIA MULTIFLORA DC, 2.1. (Lam.) Prodr. 3: 244. 1828.
