cence unknown. Infructescences terminal and
lateral, ternate or quaternate, ca. 5 cm long; pedun-
cles ca. 1 cm, cicatrose, fibrose, cylindrical, decorti-
cating on older surfaces; prophylls 3, 0.5–1.2 cm
long; bracts 6 in 2 whorls, bracts in outer whorl 1.3–
1.5 cm long, bracts in inner whorl 3.4–4 cm long;
pedicel 1.6–1.7 cm long, glabrous. Cephalium ellip-
soidal, red, 1.1–1.5 cm long, 0.5–0.6 cm wide.
Berry rhomboid, red, 1.5–2 mm long, pileus rigid;
stigmas 1–2.
Field characters. Leaves green above, pale green
below; fruits red.
Distribution. Known only from the type locality.
Habitat and ecology. Disturbed poor montane for-
est at about 1200 m altitude.
Etymology. Named after Estonian botanist Heinar
Streimann, collector of the type specimen.
Conservation status. Probably vulnerable (VU).
The Menyamya area has been extensively disturbed
by anthropogenic activities. The roadside forest
visited by Streimann has been either eradicated or
severely impacted.
INTRODUCTION
New Guinea is renowned as a centre for floristic
diversification in the paleotropics. The spacious
nature of its major families is particularly evident in
the Pandanaceae, and especially so in the genus
Freycinetia. Although Huynh (1996; 1997; 1999;
2000; 2002) recently added some species to the ge-
neric conspectus, there are still many taxa await-
ing formal description. The following account pre-
sents yet another novelty from New Guinea, lending
further support to Stone’s (1982) contention that
the island is unquestionably the centre of diversity
for Freycinetia.

ABSTRACT
KEIM, A.P. 2010. A new species of Freycinetia (Pandanaceae) from Papua New Guinea. Reinwardtia 13(2): 101–106.
⎯ Freycinetia streimannii A.P. Keim is newly described from Papua New Guinea. The novelty is closest to Freycinetia
normanbyensis Huynh but is clearly separated by differences in the size of the cephalia and in the number of stigmas.
Keywords: Freycinetia, Pandanaceae, Papua New Guinea.

2010] 105 KEIM : A new species of Freycinetia (Pandanaceae) from Papua New Guinea
Stone (1967) mentioned F. hollrungii Warburg
as a species with both terminal and lateral infructes-
cences. Indeed, with number of stigmas 1 to 2, F.
hollrungii seems to be the closest morphologically
to F. streimannii. However, I am not in accordance
with his account, as Warburg (1900) did not write
that F. hollrungii has both terminal and lateral
inflorescences and infructescences. In fact, he did
not mention anything about the position of the
infructescence except that it consists of 2 to 3
cephalia (infructescences binate or ternate). Un-
fortunately, the syntypes of F. hollrungii were
destroyed during the World War II and there is no
information about the presence of any copies in
other Herbaria. Thus, everything is based only on
the protologue. Nonetheless, the protologue is not in
favour of Stone.
Among the extra–Papuasian taxa, Freycinetia
imbricata Blume is a well–known species having
both terminal and lateral infructescences. This
species is commonly found in Java, Borneo, and the
Malay Peninsula (Stone 1970a, 1970b, 1970c,
1972), but so far has never been recorded in New
Guinea. Nevertheless, with rather globose cephalia
(9–10 × 6–7 mm) and with 3–5 stigmas, F. imbri-
cata is immediately distinguishable from F. stre-
imannii.
ACKNOWLEDGEMENTS
I am grateful to Dr. Wayne Takeuchi (A) for valuable
discussions, suggestions, and photographs of the holo-
type. Deepest appreciation is sent to Dr. Rugayah (BO)
for the encouragement. Warmest appreciation is also
mailed to Prof. N. Fukuoka (JICA) for constructive sug-
gestions to the manuscript.

Notes. In New Guinea, there are only a few species
with both terminal and lateral infructescences.
Among the congeners in this group, Freycinetia
streimannii is the only one with 1–2 stigmas. Frey-
cinetia normanbyensis Huynh is probably the clos-
est to the new species (see Huynh, 2002), but can be
easily distinguished by the characters listed in Table
1.
There are also apparent similarities between
Freycinetia madangensis and F. streimannii. How-
ever Table 2 provides a decisive compilation of
their differentiating attributes.
