Syst. Nat. 2: 522 (1821) APNI
Annual or perennial herb to 70 cm high; stems erect, not papillose or hairy. Basal leaves toothed (to very rarely pinnately lobed); stem leaves lanceolate, to 6 cm long and 5 mm wide, toothed or entire, margins glabrous or with sparse needle-like hairs. Inflorescence a dense elongating raceme. Sepals to 0.8 mm long; petals reduced, thread-like, shorter than sepals; stamens 2; stigma subsessile. Fruit ovate, elliptic or obovate, 2–3 mm long, 1.5–2 mm wide, without hairs, wings narrow, forming shallow apical notch; pedicels 2–3 mm long, shorter than or equal to fruit, minutely hairy on upper surface, somewhat flattened, mostly bow-shaped. Flowers most of year.

Similar to the native L. pseudotasmanicum, but basal leaves not pinnately divided (only 1 specimen of over 100 examined had pinnate basal leaves) and leaves with margins glabrous or with scattered needle-like hairs (obviously longer than wide). In addition, L. africanum never has papillate stems. Although fruit shape is sometimes used to distinguish the introduced L. africanum from the native L. pseudotasmanicum, there seems to be great variability in this feature.
