Two new varieties of Eugenia capparidifolia DC. (Myrtaceae), E. capparidifolia var.
illustrated. They are endemic from the Espinhaço Range in Minas Gerais (Brazil). In
addition, Eugenia monticola (Sw.) DC. var. racemosa Amsh., is elevated to species level,
receiving the new name Eugenia gerdae Mazine, since the name Eugenia racemosa is

Eugenia is currently estimated to contain
ca. 500 (Holst et al. 2003) to 2000 species
(Sanchez-Vindas et al. 2001), distributed
from South of Mexico, Cuba, the Antilles to
Uruguay and Argentina, with a small
number of species (ca. 60) in Africa (Van
der Merwe et al. 2005). Some species, with
edible fruits, have been cultivated in
tropical and subtropical regions (e.g.,
Eugenia uniflora L., E. brasiliensis Lam.).
Eugenia is the largest genus in Myrtaceae
and has the highest number of species of
tree species in the rainforests and semi-
deciduous of the Brazilian Atlantic Forest
region (Oliveira-Filho & Fontes 2000). The
most common features of Eugenia are the 4-
merous flowers, with free sepals that are
distinct in the flower bud, and with the
hypanthium little or not prolonged beyond
the summit of the ovary, which is bilocular,
with many ovules per locule.
During the preparation of the treatment
of Eugenia sect. Racemosae O. Berg from
the Neotropics, 59 species were recognized
(38 occurring in Brazil). Two new varieties
of Eugenia capparidifolia DC. have been
found and are herein described and
illustrated. Also, a new name for Eugenia
is given, once it has to be elevated to
species level and the epithet “racemosa” is
already occupied for Eugenia.
NEW VARIETIES OF EUGENIA
Endemic from Espinhaço Range in
racemes, with thick rachis. Four varieties
are recognized in Eugenia capparidifolia,
distribution, leaf base and leaf petiole.
1. Plants from Diamantina and region ....
1’. Plants from other regions of Espinhaço
Range in Minas Gerais
2. Base of the leaves generally cordate
2’. Base of the leaves acute or obtuse.........3
3. Subshrub 20-50 cm, apex of the leaf not
pendent, raceme with long peduncle (1.2-
1.9 cm long), pedicel long (0.9-1.3 cm
.E. capparidifolia var.
3’. Treelet 2.5 m, apex of the leaf pendent,
long), pedicel short (0.3-0.4 cm long)

long, 3.4-4.5 cm wide, sparsely to
moderately pubescent on both surfaces;
apex acute, not pendent; base acute or
obtuse; petiole 3-4 mm long. Raceme (1-)2-
3(-4) pairs of flowers; peduncle 1.2-1.9 cm
long. Pedicel 0.9-1.3 cm long. Fruit
COMMENTS. Eugenia capparidifolia
var. longipetiolata is endemic to the region
(Espinhaço Range in Minas Gerais, Brazil),
occurring only in cerrado. It is similar to E.
capparidifolia var. neglecta (O. Berg)
Mazine, but can be distinguished by the
base of the leaves acute or obtuse and the
cordate, rarely rounded).

midvein; apex shortly acuminate, pendent;
base obtuse; petiole 5-7 mm long. Raceme
3 pairs of flowers; peduncle 0.4-1.1 cm
long. Pedicel 3-4 mm long. Fruit
Range, in Minas Gerais, Brazil), occurring
only in riverside relicts. Known from a
single collection, this is the only specimen
of Eugenia capparidifolia that is a treelet
and can reach more than 2m tall. It has
leaves with pendent apexes and short
flower pedicels. It is similar to Eugenia
leaves with obtuse base and the treelet habit.
