Ceropegia lucida is a non-succulent climbing plant, whose stems can reach a length of about 2 m.

The leaves are broad lancet-shaped to ovate, 6,5 to 10,5 cm long and 1,5 to 2,5 cm wide. They have an 0,5 to about 1 cm long petiole.

The 1,5 to 2 cm long peduncles bear few-flowered cymes with about 7 cm long flowers.

In most parts of its natural range this species seems to have already disappeared now, such as in the Indian states of Assam and Meghalaya. In Sikkim it was considered extinct/extirpated too, but was rediscovered in the year 2009 near Lachung village in the north part of that state. Only two populations of this species, which grow at an altitude of 1750 m in a damp, shrubby grassland, are known up to now. Species conservation measures are therefore highly necessary.

Ceropegia lucida is a somewhat problematic species, not all herbarium specimens, labeled with this name, are in fact truly of that species. A revision of this and closely related species of the genus Ceropegia is therefore urgently needed.
