HABITAT ECOLOGY Pandanus leram var. andamanensium is a typical littoral species. This species grows on altitude 0.5 m above sea level, fruiting in
June. VERNACULAR NAME: Pandan wong.
NOTES: This is evidently the wild form, with much smaller phalanges than P. leram proper. Specimens from Java are intermediate in phalange size between var.
leram as it appears in cultivation, and var. andamanensium. It must likely drifted from the Andaman – Nicobars area, but could have come from farther out in the
Indian Ocean, e.g Maldive Island, attols where var. leram certainly occurs. Such drift probably accounts for the distribution of the species, especially in Javan
localities Stone 1983a. Pandanus leram var. andamanensium
appears close to P. dubius. Morphologically these species are similar to each other by sharing linear leaves,
coriaceous leaves, leaf apex abruptly terminating at once in a point. Pandanus dubius differs from P. leram var. andamanensium by three character states,
tertiary cross vein form oblong meshes, phalange cuneiform, and stigma cordate to reniform.

specimen in Hort.Bog. II C 58; living tree in Hortus Bogoriensis originated from Srigontjo, Pasuruan, Java.
Tree 10-12 m tall, the stem 10.4 cm in diameter ringed by dense leaf scars, armed with stout spine, 2-4 mm long, 5-20 mm apart, subulate, straight,
ascending; prop roots 1-3 m long, 3.3-6.8 cm in diameter, armed with similar spines. Leaves 95- 115-198.5 cm long, 2-3.6 cm wide at the middle, thin
coriaceous, above glossy dark green, below yellowish green, with a median furrow about 5 mm wide, slightly 2-pleated, but nearly flat; the midrib below
narrow 0.15 mm wide and raised; longitudinal veins visible on both surfaces about 0.4-0.55 mm apart, tertiary cross vein making oblong meshes 1-5 mm
apart, and at mid section with 25-30 secondary parallel veins on each side, the blade linear - ligulate, gradually tapering to a very long slender apex 17-20 cm
long, which 10 cm back from the tip is 1-1.5 mm wide, the base widened and amplexicaul, unarmed, but beginning 2.5-4.5 cm up the margin with denticulate -
serrate prickles, 0.5-2 mm long, 1-4 mm apart, sharp, subulate, ascending 40

reflexed prickles 3-4.5 mm long, 10-35 mm apart; at the mid section the margin with serrate, sharp, subulate, 1-2 mm long, 2–4 mm apart, ascending 15
o
, the nearby midrib below serrulate, sharp, subulate, appresed, 0.75-1 mm long, 4.5-10
mm apart, ascending at 5

serrulation, but with 1-2.5 mm apart. DISTRIBUTION: East Java.
HABITAT ECOLOGY: Pandanus multifurcatus is specifically found in the
East part of Java island, at Srigonco – Pasuruan. This species particularly grows at
the lowland areas from 5 to 20 m above sea level, flowering and fruiting in February to April.
VERNACULAR NAME: Pandan sirih. NOTES: Pandanus multifurcatus
appears close to P. spinistigmaticus. Morphologically these species are similar to each other by sharing prop roots and
bark armed with stout spine, leaf apex gradually long tapering to subulate apex. Pandanus spinistigmaticus differs from P. multifurcatus by one character state,
tertiary cross vein not visible. SPECIMENS EXAMINED:
