Leaves glossy green, smooth and thick; young leaves orangey or reddish.Flowers small and insignificant, borne along middle axis of elongated terminal racemes up to 0.6m long. 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 globuse berries that split open to expose seeds embedded in brightly-coloured fleshy pulp, probably dispersed by animals.Used occasionally as ornamental. Suitable as focal climbing or scrambling shrub in parks and large gardens for attractive leaves and prominent inflorescences. Reported to bloom throughout the year in tropics, but flowering is fairly uncommon in Singapore, perhaps due to limited use and field observations.One of only 2 species in genus. Genus epithet 'Norantea' is latinization of "Conoro-antegri", the vernacular name of the plant in Guyana. Species epithet guianensis' is a reference to French Guinea (Guyana), South America. |
