Recognizing the plant
The leaves are broadly lance-shaped to egg-shaped, up to eleven centimetres long, with smooth edges and an abruptly narrowed tip. They bear scattered hairs and are paler below. Flowers come in pairs on a shared stalk, usually two or three times longer than the flowers themselves. The corolla is yellow near its base and reddish-brown above; its short tube opens into a two-lipped mouth. The two developing fruits become completely joined, forming one dark-red berry.
