Marlierea cordata Mattos (1989: 7)

Santos, Matheus F., Stadnik, Aline, Proença, Carolyn E. B. & Sobral, Marcos, 2020, The near demise of Marlierea: moving last species to correct genera and notes on three incertae saedis taxa (Myrtaceae, Myrteae, Myrciinae), Phytotaxa 447 (3), pp. 195-202 : 196

2. Eugenia hirta O.Berg (1859: 574) .

Type:— BRAZIL. Bahia: [likely Mun. Ilhéus], “ In siccis arenosis prope Ilheos,” January 1822 (fl), Riedel [633] (lectotype, designated here: LE [image!] [ LE00007398 ]; isolectotypes: LE [image!] [ LE00007384 ]) .

= Marlierea cordata Mattos (1989: 7) , syn. nov. Type:— BRAZIL. Espírito Santo: Mun. Conceição da Barra, “matinha que acompanha a faixa de dunas”, 15 December 1962 (fl), Mattos 10806 (holotype: FLOR [image!]).

The type of Marlierea cordata does not have the hypanthium extended above the ovary and splitting vertically at anthesis, features which are typically associated with Marlierea . According to the morphological evidence, M. cordata is clearly a synonym of Eugenia hirta , as demonstrated by its cordate leaves, umbelliform (to uniflorous) inflorescence with bracts at the base, persistent bracteoles and ovary with more than two ovules per locule.

3. Myrcia rufopilosa M.F.Santos , nom. nov. Replaced name: Myrtus rufa Vellozo ([1825]1829: 217). Marlierea rufa (Vell.) O. Berg (1855: 18) .

Type:— BRAZIL. Rio de Janeiro [specimen lost] (lectotype, designated here: original parchment plate of the Florae Fluminensis deposited at the Manuscript Section of the Biblioteca Nacional of Rio de Janeiro, latter published in Vellozo ([1827] 1831, v. 5, tabula 75). Epitype, designated here:— BRAZIL. Espírito Santo: Mun. Santa Teresa, Estação Biológica Santa Lúcia, 28 September 1999 (fl), Demuner 28 ( SPF!; isoepitype: MBML!) .

The characterization of the species described by Vellozo (1829, 1831) is not obvious as the diagnoses is short and the type specimens were lost (e.g. Lima 1995, Cervi & Rodrigues 2010, Chagas et al. 2018). Sometimes, the plates are essential to verify the species morphology, this being the case of Myrcia rufopilosa . The protologue (Vellozo 1829) describes the leaves as glabrous (“ folia glabra ”), but the plate (Vellozo 1831) shows the hirsute indument of young leaves (and bracts) in the flowering branch – described by Vellozo (1829) as “ pedunculi apex abiit in duo foliola hirsuta ”; the basionym and the new name refer to this feature. The spiciform inflorescence and closed floral bud suggest affinities with Myrcia sect. Aulomyrcia (O. Berg 1855: 35) Grisebach (1860: 234) ( Lucas et al. 2016, 2018).

A new name is necessary because Myrcia rufa (O. Berg 1857: 65) D. Legrand (1961: 298) is already published. We found recent collections (e.g. Demuner 28 [MBML, SPF], Martinelli 11878 [MBML, SPF]) that match the original concept of Myrtus rufa and an epitype was chosen to establish the application of the name.
