5. Myrcia lenheirensis Kiaerskou (1893: 98)

≡ Eugeniopsis angustifolia O. Berg (1857 –1859: 143). Marlierea angustifolia (O.Berg) Mattos (1967: 333) . Type:— BRAZIL (“Brasilia” on label). No date (fl.), Sellow s.n. (lectotype K [K000330701]! designated here, isolectotypes BR!, LE!, P!). Figure 6 .

The name Marlierea angustifolia has been commonly used to identify this species ( Govaerts et al. 2015, Sobral et al. 2015). However, Myrcia lenheirensis is the correct name. The species is more properly placed in Myrcia due to morphological discordance of the species with the morphology of Marlierea (it has free calyx lobes and a hypanthium not tearing after the anthesis) and the ongoing synonymization of Marlierea in Myrcia . The new name M. lenheirensis was proposed by Kiaerskou (1893) because of the older name Myrcia angustifolia (O. Berg 1857 –1859: 135) Niedenzu (1893: 76).

The material at K ( Figure 6 )was chosen as the lectotype because it has Berg’s handwriting on the label (“ Eugeniopsis angustifolia Bg ”) and the material matches well with the protologue and represents the species’ morphology. The labels on the type collections in the Botanic Garden Meise (BR) and V. L. Komarov Botanical Institute (LE) herbaria also bear Berg’s annotation. Material at K and LE have the number “1335” on the label.

The protologue of Eugeniopsis angustifolia ( Berg 1857 –1859) cites the locality as “Habitat ad ripas in montibus Serra do Caraça, Prov. Minarum” and “campis montium Serra do Lenheiro”. As there is just one gathering, it is not clear why Berg (1857 –1859) cited two localities. It is also not clear from where he took this information, as the localities in the labels are just “Brasilia” (if present). As both localities are part of Sellow’s route ( Urban 1906, Herter & Rambo 1953) and within the distribution of M. lenheirensis , it is not possible to precisely infer the type locality.
