Information
Nearly glabrous to hairy laticiferous perenni­al with brownish black, tuberous, fusiform tap­root up to ± 100 mm in diameter. Stems annual, several from base, usually all ultimately pros­trate, up to 750 mm long. Leaves very variable in shape and size, usually lanceolate to ovate, 15-80 x 3-28 mm, apex acute to obtuse, base usually truncate to rounded, entire; petiole up to ± 10 mm long. Peduncles usually 1-flowered; bracts leafy, variable in size and shape, ovate-lanceolate or lanceolate-oblong, 5-20 mm long; pedicels usually shorter than 20 mm. Sepals unequal, 10-28 mm long, outer ones ovate, ± triangular or lanceolate, base often subcordate, inner ones linear. Corolla funnel-shaped, mauve to purple with lighter midpetaline areas, also pink or white with dark purple centre, 30-45 mm long, 35-60 mm wide. Capsule ovoid-glo­bose, glabrous, apiculate, 8-10 mm in diameter. Seeds glabrous or pubescent, ± 6 mm long. Flowering time September to April, mostly November to January.
Habitat
Distinguished by its prominent, leafy bracts, unequal sepals and 30-45 mm long, pinkish corolla. This extremely variable species is con­ceivably an aggregate taxon. It would seem that all specimens from southern Africa could belong to the typical variety.
