Narrowly heart-shaped and hollow structures are modified extrafloral nectaries (nectar pouches), mature from orange to dark red. Flowers pollinated by hummingbirds and other small perching birds. Fruits are globose berries that split open to expose seeds embedded in brightly-coloured fleshy pulp"  (National Parks of Singapore).

"A woody climber with alternate, leathery, elliptic to obovate leaves, 4-6 in. x 2-3.25 in., it bears terminal racemes to 4 feet long consisting of red-orange flowers, mostly hidden among similarly colored nectar-producing tubular appendages open at the top; these appendages (modified bracts) make up the visible bulk of the inflorescence.  The fruit is a dehiscent capsule containing many tiny seeds"  (Staples & Herbst, 2005; p. 393).
