Description

Pholistoma membranaceum is an annual herb with a waxy, fleshy, bristly stem up to 90 centimeters long and branching profusely, sometimes forming a tangle. The leaves are deeply lobed or cut and borne on winged petioles. The foliage is coated in hairs.[2]

The inflorescence consists of cymes of 2 to 10 flowers each under a centimeter wide. Each pedicel is 5–20 millimetres (0.2–0.8 in). Calyx lobes are oblong and 1–3 millimetres (0.04–0.12 in). The flower is white, usually with a purple spot or streak on each of its five lobes.[2]
