Notes.
–
Although three duplicates of
Cribs 1496
are deposited in
P
, only
P00637580
has the species name and type annotation in Guillaumin’s hand. We consider this sheet as the
holotype
because the two other sheets at
P
have clearly not been studied by Guillaumin
.
The locality on the label initially indicated the year 1904, but the number “4” was crossed out and replaced with a “3”. The word “Sébertville” on the label refers to the Sebert Camp of the 1870s, which later became Prony.
A new name is proposed for the later homonym
Eugenia calycorectoides
Guillaumin.
The epithet
pubiflora
alludes to the dense pubescence on the inflorescence axis, hypanthium, and calyx lobes.
Eugenia pubiflora
N. Snow & Callm.
differs from its congeners by its densely, grayish pubescence on emerging leaf blades, young pedicels, and hypanthium (
Fig. 3B
).

Notes.
– The
holotype
material of
Xanthomyrtus pergracilis
Diels
was destroyed in
B
(
HIEPKO, 1987
). The best preserved duplicate at
P
[
P00835846
] is designated here as the
lectotype
.
Xanthomyrtus pergracilis
has been considered as a synonym of
Eugenia sarasinii
Guillaumin
by
GOVAERTS et al. (2008)
, which is followed here.

Notes.
–
The
protologue indicates “Habitat in Novae Caledoniae montibus ferrugineis” and “Pancher, [anni] 1860–62” as collector.
Three
sheets collected by
Pancher
at
P
bear on the label “coteaux ferrugineux”. The best-preserved specimen is designated here as the
lectotype
.
Two
additional specimens collected by
Pancher
[
K000821576
,
P05094559
] seem to represent a separate gathering and are not considered as original material
.
Eugenia stricta
Pancher ex Brongn. & Gris
is one of the most widely distributed and abundant species of the genus in
New Caledonia
. Its (1–)
2–5 cm
long, obovate leaves with a (usually) retuse apex, coupled typically with solitary terminal or axillary flowers, make it easily recognizable.
