8. Myrcia plusiantha Kiaerskou (1893: 66)

Type:— BRAZIL. Rio de Janeiro [“Brésil (Rio Jan.) Alto Macahé” on label], 5 March 1888 (fl.), Glaziou 16994 (lectotype C [ C 10015882]! designated here, isolectotypes BR!, C [ C 10015883]!, F!, G!, K!, LE!, NY!, P!, R!, RB!). Figure 13 .

= Myrcia follii G.M. Barroso & Peixoto (1990: 4) , syn. nov. Type:— BRAZIL. Espírito Santo: Mun. Linhares, Reserva florestal da CVRD, Est. Farinha Seca, ant. 221, km 4.140 lado direito, 23 November 1988 (fl.), Folli 821 (holotype CVRD!, isotypes RB!, SPF!)

Myrcia plusiantha :— Kiaerskou (1893) cites the collection Glaziou 1694 in the protologue of Myrcia plusiantha , a typographic error. At the C herbarium, where Kiaerskou worked, the two duplicates of Glaziou 16994 bear the author’s handwriting (“ Myrcia (Aulomyrcia) plusiantha ”). The material illustrated in the protologue (one leaf, Tab. X, a, b; Kiaerskou 1893) is selected as the lectotype ( Figure 13 ); the draft of the illustration is attached to this sheet. The locality cited in some labels of the type collection (“Alto Macahé”, i.e., the region of Macaé de Cima, in the municipality of Nova Friburgo, Rio de Janeiro state, Brazil) agrees with the species distribution and is here considered the type locality.

Myrcia follii :—The type collection of Myrcia follii and other specimens from the region of Linhares (Espírito Santo state, Brazil), despite denser indument and less reticulate venation, do not show significant differences from collections of Myrcia plusiantha . Furthermore, both species share a set of diagnostic characteristics within the clade: sympodial branching, larger leaves than average in clade 7, cataphylls present at all internodes, twigs not keeled and turbinate floral buds. For these reasons, M. follii is here reduced to a synonym of M. plusiantha .
