The Myrtaceae are among the most species-rich families of
flowering plants in New Caledonia (Dawson 1992, 1999 ;
Morat et al., 2012, Ibanez et al., 2014). Many species of
the family are known from relatively few collections and
at least thirty additional new species in four or five genera
remain to be described in addition to those proposed here
(Snow, unpubl. data).
Among the less studied genera of Myrtaceae for New
Caledonia is Eugenia l., one of the largest exclusively woody
genera of plants (lucas et al., 2007 ; Govaerts et al., 2008 ;
Biffin et al., 2010). The native distribution of Eugenia occur-
ring in both the neo- and paleotropics is unique among the ca.
140-150 genera of Myrtaceae (Snow et al., 2011).
The greatest specific diversity of Eugenia occurs in the
neotropics (landrum & Kawasaki, 1997 ; Mazine et al.,
2014). Areas of particularly high diversity include the Atlantic
Coastal forests (Mâta Atlantica) of Brazil, the Caribbean,
MesoAmerica (e.g., Barrie 2005, 2009) and the Northern
Andes (landrum & Kawasaki, 1997). The relative paucity of
et al., 1983) may be explained partially by the relatively low
stature of many species and their often irregular flowering,
which may limit dispersal of fruits, range expansion and diver-
sification rates, although low stature and irregular flowering
are not universal characters among species of Eugenia.
In addition to its richness in the New World tropics, Euge-
nia also has substantial levels of diversity in the paleotropics,
particularly in Madagascar (Snow, 2008, 2011 ; Biffin et al.,
2010 ; Snow et al., 2012, 2015), southern Asia, the Como-
ros (Byng et al., 2016), and New Caledonia. Given known
but unpublished taxa in preparation (e.g., Snow et al., 2015),
which includes perhaps 50 additional undescribed species
from Madagascar and New Caledonia, we estimate that up to
30 % of the diversity of Eugenia may occur in the paleotropics.
Critically from a phylogenetic perspective, the paleotropical
diversity in Eugenia appears to reflect a significant part of the
known morphological variation in inflorescence morphology,
calyx lobe fusion and splitting, flower size, fruit size and testal
morphologies, as well as some characters not (yet) known in
the neotropics, such as dioecy (van Wyk & lowrey, 1988 ;
Byng et al., 2016). Inferring the phylogeny of the genus will
benefit from proportional sampling across the Old and New
Based on revisionary studies currently in progress, Eugenia
species, many of which remain to be described besides those
proposed here (Snow et al., unpubl. data). The primary purpose
of this paper is to propose five new species in detail, inclu-
ding preliminary conservation assessments following IUCN
Red list Categories and Criteria (IUCN, 2012). In addition,
we address needed nomenclatural transfers and matters of
typification. We have seen all available material at G, NOU,
MO and P. Terminology largely follows previous recent stu-
dies of Eugenia by NS (e.g. Snow et al., 2015) but includes
some terminology from Briggs & Johnson (1979) regarding
inflorescence structure and shapes, and other terms following
The new species and new combinations proposed here
bring the total number of described species of Eugenia in New
Caledonia to approximately thirty-five.

in which the calyx lobes split radially during anthesis towards

for Spermolepis rubiginosa is : “hab. in collibus ferrugineis Novae
Cale doniae (Pancher, 1862)” (Brongnart & Gris, 1863 : 577).
Even though several collections by Pancher are deposited at P,
only two of them are dated 1862 [P00402683, P00637569]. Of
these two specimens, the latter [P00637569] shows the habitat as
“coteaux ferrugineux”, which closely matches the prologue infor-
mation, and thus can reasonably be considered as the holotype.
This assessment is strengthened by the fact that Brongniart and
Gris were working in P. However, some authors might consider
the protologue citation as insufficient to consider this specimen
[P00637569] as the holotype as discussed below.
Within the protologue, Brongniart and Gris did not
mention “Pancher, 1862” at P as being most representative.
Since two Pancher specimens at P show the date 1862, one may
argue that there is no evidence that the two specimens belong
to two gatherings, that it is uncertain that Brongniart and Gris
based their new species only on P00637569 specimen alone, and
that therefore, a lectotype designation is needed (McNeill et al.
2014). Because of the uncertainty, we designate the P00637569
specimen as the lectotype, and at the same time we do not rule
out the possibility that it could be a holotype.
they believed was a new genus : Spermolepis Brongn. & Gris 1864
(non Raf. 1825). later, they transferred the preceding species
to Schizocalyx O. Berg 1856 (non Scheele 1843). Sub sequently
Guillaumin transferred the species into the neotropical genus
Calycorectes O. Berg because of the fused calyx lobes associated
with that genus (see landrum & Kawasaki, 1997).
No preliminary molecular data are available for species of
Eugenia in New Caledonia that have the splitting calyx lobes typical
of E. vieillonii (Fig. 7). However, preliminary phylogenetic studies
show Calycorectes to be nested within Eugenia s.l. (lucas et al.,
2007 ; Mazine et al., 2014), the members of which also have fused
calyx lobes that split during anthesis. This character likely has arisen
in parallel, given that it recurs in the Malagasy E. ambanizanensis
N. Snow (Snow, 2008), another undescribed species from Mada-
gascar (Snow, ined.), several in the Mascarenes described initially in
ferred later into Eugenia (Snow, 2008), and the recently described
A new name is needed because the epithet rubiginosa is una-
vailable in Eugenia. The new epithet “vieillonii” honours our col-
league Jean-Marie Veillon (b. 1939). Jean-Marie is an expert on
the flora of New Caledonia and has made over 8000 collections
from the Island. His numerous works, including two volumes of
the “Flore de Nouvelle-Calédonie et Dépendances”, have con-
tributed significantly towards overall progress on the knowledge
of New Caledonia’s flora.
