Morphology Reproductive morphology Flowers Perianth
Perianth tube greenish, 12–14 cm; segments connivent to a bell, distinctly hooded, with reflexed apical parts at anthesis, greenish keel and deep pink veins covering all sun-exposed areas, outer segments 10–11 × 2.3–2.8 cm, inner 9–10 × 3–3.5 cm.
Morphology Reproductive morphology Flowers Androecium Stamens Filaments
Filaments white, 8–9 cm; anthers 10–12 mm, blackish with a whitish longitudinal line.
Morphology Reproductive morphology Flowers Gynoecium Style
Style reddish in outer part, slightly longer than the filaments.
Morphology Reproductive morphology Fruits
Fruits greenish, turning brown before bursting, with thin pericarp, up to 3 cm long and 2.5 cm wide.
Morphology Reproductive morphology Seeds

Ecology
In seasonally flooded heavy clays within mopane woodland; c.600 m.
Conservation
Conservation notes: Endemic to the Mfuwe area of the central Luangwa Valley, where it is rare. Owing to current threats, and as two of the three known populations lie outside any Protected Area, the species is considered Endangered 2a. If other populations are found it would become Vulnerable D2.
