      Merremia dissecta grows as a perennial herbaceous vine that is covered with sparse pubescence. The leaves are arranged alternately and to 10 cm in length. The leaf blade is palmate with 7-9 lobes. The lobe margins are sinuate to dentate with an acuminate apex.The complete, perfect, actinomorphic flowers are solitary, though occasionally in cymes. The calyx has 5 unfused oblong sepals. The salverform corolla has 5 fused petals that are white with a red center. There are 5 stamens fused to the throat of the corolla tube. The ovary is superior with 2 locules and numerous seeds. The fruit is a capsule at maturity. Subtending the fruit are the sepals that become dry and woody.
