HABITAT ECOLOGY: Pandanus bantamensis occupies very wide habitat ranges. Some are found on hill forest, but mostly found growing on lowland areas
below 500 m and lower montane forest below 1500 m. Only few are found on upper montane forest higher than 1500 m above sea level, flowering and fruiting
in June to November. VERNACULAR NAME: Pandan betok, pandan kowang, pandan cangkuang.
NOTES: Pandanus bantamensis appears close to P. pseudolais. Morphologically these species are similar to each other by sharing prop roots muricate in lines,
blade linear, leaf coriaceous, leaf base reddish, leaf apex gradually long tapering to subulate apex, apical ventral pleat smooth, tertiary cross vein form oblong
meshes, and recurved spine present. Pandanus pseudolais differs from P.
bantamensis by two character states, style hornlike and stigma ellipsoid or lanceolate.

HABITAT ECOLOGY: Pandanus bidur is a typical littoral species, This species grows on altitude 0 to 5 m above sea level, fruiting in April to July.
VERNACULAR NAME: Bidur. NOTES: Pandanus bidur appears close to P. dubius. Morphologically these
species are similar to each other by sharing prop roots long 4 m high, blade linear, leaf coriaceous, leaf apex abruptly terminating at once in a point, tertiary cross
vein form oblong meshes. Pandanus dubius differs from P. bidur by three character states, phalange cuneiform, stigma cordate to reniform, and endocarp
median. SPECIMENS EXAMINED: — WEST JAVA: Ujung Kulon, Bantam-Mt. Payung,
