Geographical Distributions

Merremia hederacea is distributed from tropical Africa, Mascarene Islands, tropical Asia, from the Himalayas southwards to Sri Lanka, and eastwards to Burma (Myanmar), southern China, Indo-China and Thailand, and southwards throughout Malesia to northern Australia. [2]

Botanical Description

M. hederacea is comes from the family Convolvulacea. It is an annual, twining or prostrate, slender herb, with a size of measuring 1-2 m long and it is smooth to sparsely hirsute. [2]

The leaves are ovate in outline, with a size of measure about 1.5-5 cm x 1.2-4 cm, broadly cordate base, obtuse apex and mucronulate in shape. The leaves margin is an entire or crenate to shallowly or deeply 3-lobed while the petiole is measure about 0.5-6 cm long. [2]

The flowers are few to several. The first ramification is dichasial while the subsequent ones are often monochasial. The peduncle is measuring about 1-10 cm long, with a size of measure 3 mm long of the narrow-obovate bracts and caduceus. The flower-buds are oblong in shape, a size of measure about 2-4 mm long pedicel, concave sepals, broadly obovate to spoon-shaped, with a size of measuring 4-5 mm long, broadly notched at the apex and mucronulate. The measuring  6-10(-12) mm long petal is bell-shaped. It is hairless outside and with long hairs inside. It is a yellow in colour while the base of filaments is hairy. [2]

The capsule is broadly conical to depressed-globular in shape, with a measuring about 5-6 mm high and wrinkled. The seed is measure about 2.5 mm long and it is pubescent or nearly smooths. [2]


M. hederacea occurs in thickets, open grasslands, and on sandbanks, from sea-level up to 250 m altitude. Two forms can be distinguished: f. pubescens Ooststr., with shortly pubescent seeds, and f. barbata Ooststr., with seeds having reddish-brown long hairs on the hilum and margins when ripe [2].
