Notes

In the Flora Zambesiaca area, this species is known only from 2 collections.These were made by the same person in Malawi, between 1915 and 1919.Although the area has been well collected and this species actively sought, it has not been found since.As most of the land around the base of Mt. Mulanje has been planted with tea, it is possible that the species no longer exists in the area; however, if it came from the forests on one of the plateaux, it could still reappear.It is not the only example of a species with a West African distribution occurring in Malawi; that of Eggelingia clavata is similar.
