Geographical Distributions
Merremia peltata is distributed throughout from Madagascar, Mascarene Islands, Seychelles, throughout Malesia, to North and East tropical Australia and Polynesia. [2]
M. peltata occurs along edges of primary and secondary forests, clearings, and thickets, from sea-level up to 700 m altitude. Yellow-flowered specimens appear to be restricted to West Malesia, the white-flowered ones to East Malesia. [2]

Botanical Description
M. peltata is comes from the family Convolvulaceae. It is a large perennial twiner, which can grow measuring about 5-30 m long. It is rarely precumbent, with terete stems, fistulose or pithy, hairless, with milky juice and with large tuber. [2]
The leaves are peltate, broadly ovate to orbicular in shape, with a size of measuring 7-30 cm in diametre, rounded base, acuminate apex and mucronulate. The petiole is measure about 3-20 cm long. The flowers are in a 2-many-flowered corymb that up to measure 40 cm long. The peduncles are 1-2 and stout while bracts are caduceus. [2]
The flower-buds are narrowly ovoid or acute in shape, with a size of measure about 1.5-2.5 cm long pedicel and club-shaped in fruit. The measuring 15-25 mm long sepals are subequal. The outer ones is broadly ovate and obtuse apex. Meanwhile the petal is broadly funnel-shaped, with a size of measuring about 4.5-6 cm long, shallowly lobed, white and sometimes yellow in colour. The anthers are spirally twisted and hairy. [2]
The capsule is ovoid in shape. The hairy seed is densely yellowish to dark brown in colour. [2]
