9. Myrcia subavenia View in CoL (O. Berg 1857 –1859: 69) N. Silveira (1985a: 66)

Aulomyrcia subavenia O.Berg. Type:— BRAZIL (“Brasilia” on label). No date (fl.), Sellow s.n. (lectotype LE! designated by Sobral et al. 2010, isolectotype K!). Figure 14 View FIGURE 14 .

= Aulomyrcia ferruginea O. Berg (1857 View in CoL –1859: 552). Myrcia lapensis N. Silveira (1985a: 67) View in CoL . Type:— BRAZIL. Minas Gerais (“ad ripas rivul. S. da Lapa” on label), November 1824 (fl.), Riedel 972 (lectotype LE [LE00007061]! designated here). Figure 15 View FIGURE 15 .

Aulomyrcia subavenia View in CoL :— Sobral et al. (2010) designated the lectotype of Aulomyrcia subavenia View in CoL mentioning the material Sellow 1041 at the LE herbarium ( Figure 14 View FIGURE 14 ). This number, as stated before, is not Sellow’s collection number and the lectotype is cited here as Sellow s.n.

Berg (1857 –1859) cites in the protologue of Aulomyrcia subavenia , the locality “Habitat ad ripas prope Timbopeva in prov. S. Pauli”. However, A. subavenia has not been reported from São Paulo state (=“prov. S. Pauli”) or from any area close to the state boundary. The locality on the type collection label is vague (“Brasilia”). The erroneous locality is here assumed to be a mistake of the author and the locality of the type collection remains unclear.

Aulomyrcia ferruginea :— Berg (1857 –1859) cites material of the LE herbarium in the protologue of Aulomyrcia ferruginea (“hb. Hort. Bot. Petrop.”). Three sheets of Riedel’s collection of A. ferruginea were found at LE. Two of them (barcodes LE00007061 and LE00007062) bear Berg’s handwriting (“ Aulomyrcia ferruginea Bg. ”) and the same number (“972”). Both specimens were collected in the same area (Serra da Lapa), but they appear to represent different gatherings as Riedel’s labels each have different data. These specimens are here considered syntypes; the most complete is designated as the lectotype of A. ferruginea ( Figure 15 View FIGURE 15 ). The last specimen (barcode LE00007044) is from the same region but does not bear the same number as the other sheet. There is no evidence that this material was seen by Berg as his handwriting is not on the label; this specimen is therefore not considered part of the type gathering.

There is a Riedel collection at P herbarium that does not bear Berg’s handwriting but is identified as A. ferruginea and there is an indication that it was analysed by Berg (“Teste Berg”); this is here taken as evidence that the specimen is part of the type gathering. The label of the P specimen does not have any information indicating which material at LE is its duplicate, but the morphology (especially the young leaves) led us to deduce that it is a duplicate of the specimen LE00007062 at LE herbarium. Thus, we consider it as a remaining syntype and not as an isolectotype .

The locality on the labels of the type collection (“Serra da Lapa”) and in the protologue ( Berg 1857 –1859, “Habitat ad ripas rivulorum in montibus Serra da Lapa prov. Minarum”) corresponds to the current region of the Serra do Cipó (Minas Gerais state, Brazil). This locality matches the species distribution and Riedel’s route ( Urban 1906) and is here taken to be the type locality.
