Pacific. Forms of P. tectorius are also well-known in cultivation, several of them known under horticultural “species”name, viz P. tectorius cv. Sanderi Stone
1976. Stone 1988 noted “variegated – leaf mutants of P. tectorius, known in horticulture which can back-mutate to all green leaf forms. The mutant cultivar
P. tectorius cv. Sanderi is cultivated as an ornamental in Java. Leaves of P. tectorius cv. Sanderi have longitudinal white to pale yellow from center of leaf to
margin. In fully expanded leaves, the midrib is bent and the upper third or so in the leaf hangs down, giving pandan plant their characteristic drooping appearance.

DISTRIBUTION: West Java. HABITAT ECOLOGY: Pandanus utilis found in home yard and cultivated as
ornamental plants, fruiting in March. NOTES: Pandanus utilis
appears close to P. odoratissimus. Morphologically these species are similar to each other by sharing coriaceous leaves, apical ventral
pleat absent, leaf apex gradually long tapering to subulate apex. Pandanus
odoratissimus differs from P. utilis by four character states, prop root and bark
armed with stout spine, blade ligulate, and phalange obovatus. USES: Ornamental plants in the garden around houses.
