Corona set in lower half of corolla tube; lobes violet to maroon, 2 mm long. Follicles vary narrowly deltoid-ellipsoid to deltoid-ovoid, 2-edged, 11–25 cm long, 2–4 cm diameter, hairless.
Notes: Known only from one dying location on the Runde River in Gonarezhou National Park; only one plant seen recently.
