Cephalium 35 cm long, 28 cm wide, ellipsoid with about 52-94 phalanges. Phalanges when green well crowded, but when ripe becoming distant due to the
swelling of the fleshy bases. Phalanges 5.5-6 cm long, the upper half 5-6 cm wide, and 3.2-3.6 cm thick, the lower half form 5-10 mm wider and thicker due to its
fleshy enlargement, carpel 11 - 13 -16-17. DISTRIBUTION: West Java to Central Java.

c. cv. Sanderi
P. sanderi Hort. Warb., Engl. Pflanzenr, 3, IV. 9: 87. 1900; Backer Bakhuizen van den Brink, Fl. Java 3: 225. 1968.
Leaves of P. tectorius cv. Sanderi have longitudinal white to pale yellow band from center of leaf to margin and never produce fruit.
HABITAT ECOLOGY: Pandanus tectorius cv. Sanderi found in home yard and cultivated as ornamental plants.
NOTES: As interpreted by Warburg 1900 and most later author, P. tectorious is a polymorphic and wide spread species native across a broad area of the tropical
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.
