Geographical Distributions

C. floribunda is distributed from India and Burma (Myanmar), through Indo-China and Thailand, to Peninsular Malaysia (Langkawi Island, Penang, Pahang).


This is a large scandent shrub or liana, which can reach up to 10 m long. Its young branchlets are dense with yellow short soft hair.

The leaves are arranged opposite, egg-shaped to narrowly elliptical, 6-17 cm x 2-7 cm, entire and dense with yellow short soft hair, particularly below. The petiole is 0.5-1 cm long while the stipules are absent.

Inflorescence is an axillary and terminal panicle. Flowers are bisexual, yellowish-green and they are about 1 cm long. The receptacle is divided into lower and upper parts. The sepal is with 5 accrescent lobes. Petals are absent. There are 10 stamens in 2 whorls, inserted within the upper receptacle. The disk is cupular. The ovary is inferior with 1-locular while style is subulate.

Fruit is an ellipsoid, 5-gonous and 5-furrowed pseudocarp. It is about 8 mm long, densely villous, crowned by enlarged up to 1.5 cm long sepal-lobes and 1-seeded.

Seed is 5-6 mm long. 

Ecology / Cultivation

In Peninsular Malaysia, C. floribunda occurs in mixed forest, often along riverbanks. In Cambodia, it is locally common in forest edges and in regrowth after deforestation. It may have a shrubby habit, for instance inside the forest, but it may become a liana when more light is available, climbing into the trees.
