Stipules are recurved thorns about 1-3 mm long (or longer) which assist in climbing. Not present at every leaf. Leaf blades about 6-14 x 2-6.5 cm, petioles about 0.6-1.7 cm long. Lateral veins about 8-20 on each side of the midrib, forming loops inside the blade margin. Oil dots often elongated. Apex of the leaf blade ends in a thickened sharp point quite capable of penetrating the skin.
Flowers strongly perfumed. Sepals about 2.5-3.5 cm long. Outer pair of sepals fused to form a calyptra which splits irregularly. Inner pair of sepals free from one another. Petals about 4.5 cm long, dimorphic, two long and two shorter. Stamens about 80, filaments about 8-10 cm long, anthers about 0.2 cm long. Gynophore about 6.5-10 cm long.
Cotyledons stipulate, ovate or elliptic, about 30-43 x 14-21 mm, petioles about 1.5-2 mm long. Cataphylls usually 1 or 2 before the first pair of true leaves, stipules spinescent. First pair of true leaves elliptic, apex aristate or pungent pointed, base obtuse, leaf blades smaller than the cotyledons, stipules needle-like, about 5-9 mm long. At the tenth leaf stage: leaf blade elliptic, apex aristate, base shallowly cordate. Stipules are straight spines about 7-12 mm long. Petioles and stem densely clothed in short pale hairs. Seed germination time 32 to 33 days.
