Description

An annual herb, to 70 cm, slightly to densely hairy. The leaf blade is ovate, up to 8 cm long, 3–6 cm wide, entire or shallowly lobed, and petioles to 4.5 cm long. Clusters of 3–8–flowers in the inflorescence. The corolla is white or may be purple-tinged. Followed by dull light red or orange-yellow (depending on subspecies) globular berries, 5–9 mm diam. The seeds are 1.7–2.3 mm long and pale yellow. Compared to S. nigrum, aside from fruit colour the peduncles are moderate (S. nigrum peduncles can become quite long relative to the pedicels).^[4][5]
