Annual, seed-propagated weed with taproot; up to 40 cm (15.74 inch) tall.

Swollen stem nodes, stems square in cross-section. Pink-to-bluish-purple flowers arising from the axils.

Cotyledons: Strong, smooth-edged, oval-stemmed, with two lobes at the base and a rounded tip.

Stems: Square in cross-section, with swollen stem nodes; simple or branched, rough owing to their stiff hairs.

Leaves: Long oval in shape, with downy hairs on both sides, with large regular teeth and reddish-brown stem.
