Lepidium africanum

Lepidium africanum, commonly known as African pepperweed or peperbossie, is a small annual to short-lived perennial herb in the family Brassicaceae native to southern and eastern Africa and now widely naturalised across the warm regions of Australia, South America, and southern Europe. It grows 10-50 cm tall from a slender taproot, with branched, ascending stems and pinnatifid to pinnate basal leaves whose lobes are toothed or further divided; stem leaves are smaller and narrower. Numerous tiny white flowers, each about 1-1.5 mm wide and lacking petals or with reduced petals, are borne in slender elongating racemes throughout spring and summer. The fruit is a small, flattened, orbicular to broadly elliptic silicle 2-3 mm long, notched at the apex and containing a single seed in each locule. It is a common weed of roadsides, fallow paddocks, and disturbed ground.
