Euphorbia remyi var. remyi is a vine-like, perennial shrub in the Euphorbiaceae (spurge) family. Stems are erect to scandent (climbing) and 0.3 to 2 m (1 to 6.6 ft) long. Leaves are oppositely arranged with each succeeding pair set at right angles to the previous pair, elliptic to oblong or broadly lanceolate in shape, 35 to 165 mm (1.4 to 6.5 in) long, and 15 to 75 mm (0.6 to 3 in) wide. Inflorescences are solitary cyathia (an inflorescence consisting of a cuplike cluster of modified leaves enclosing a female flower and several male flowers) with glabrous capsules protruding well beyond the top. Seeds are white to brown, 2 to 3 mm (0.08 to 0.12 in) long, and smooth to shallowly rugose (wrinkled).
