Peduncles 1-flowered, short, silky pubescent as are bracteoles, pedicels and calyx; bracteoles 8-18 mm long; pedicels very short. Sepals subequal, lanceolate, 15-18 mm long, up to 28 mm long in fruit. Corolla salver-shaped, tube 70-100 mm long, narrowly cylindric, greenish white and silky outside, deep magenta and glabrous inside; limb white, 45-60 mm wide, spreading, silky on midpetaline areas outside. Capsule ovoid, 19-23 mm long, hairy to glabrous. Seeds ±10 mm long, densely covered with very long, shiny, brownish hairs. Flowering time November to May.
