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
.
