    Annual, to 1 ft. high
    Petals 4, pink or mauve.
    Very similar to Osbeckia decandra (Sm.) DC. but distinguished by the 4-merous flowers and connectives with well-developed appendages.

    Erect annual, rarely behaving as a biennial, (2.5–)4–35 cm. high; stem simple or branched, 4–angled, with appressed hairs on the angles, hairs somewhat spreading at the nodes.
    Leaves decussate, progressively larger towards the inflorescence, often widely spaced (internodes up to 22 cm.); lamina narrowly ovate to oblong-ovate, up to 3.8 cm. long and 1.4 cm. wide, apex obtuse, base cuneate to subtruncate, sparsely strigose above and on the nerves beneath; venation impressed above, prominent beneath, with 3 or 5 ascending nerves; petiole 1–5 mm. long, pilose.
    Inflorescence terminal or axillary, subtended by 1–2 pairs of leaves, capitate, up to ± 12-flowered; pedicels up to 3 mm. long.
    Calyx 2.5 mm. long, 2 mm. in diameter, sparsely hairy; lobes narrowly triangular, persistent, 1 mm. long, with reddish stellately arranged bristles at the apex; intersepalar appendages ligulate, with reddish stellately arranged bristles at the apex.
    Petals 4 mm. long, 3.5 mm. wide, pale mauve, with a tuft of hairs at the apex.
    Stamens 3.5 mm. long; anthers 0.7 mm. long; free part of connective ± 0.5 mm. long, arched, 2-tubercled at the base.
    Capsule rounded, 2.5–3 mm. long.
    Seeds 0.4–0.5 mm. long, very finely papillose.
    Fig. 3.
    Short grassland, usually in damp places, rock crevices and pavements, also by lakes, rivers and ditches; 300–2150 m.
    widespread in the forest margins and relic forest areas from Guinée across to Ethiopia and south to Angola and the Transvaal, also Madagascar, where it is believed to have been introduced (Perrier de la Bâthie, Fl. Madag. 153, Melastom.: 7 (1951)) K2 K3 K5 T1 T3 T4 T5 T7 T8 U1 U2 U3 U4
