Although abundantly common in Mozambique this species is still very local in Zimbabwe. kNot recorded for Zimbabwe in Wild
(1967). It was First reported for Zimbabwe from Rainham Dam (R B Drummond, pers. comm.) First noticed by co-author Mark Hyde on the roadside verge in Chancellor Avenue, Harare in c.1990, but not collected until 1993, by which time the species had spread intermittently northwards along Chancellor Avenue as far north as the Veterinary Research establishment and southwards to about 100
m south of Josiah Tongogara Avenue. Further plants had also appeared in Fifth Street extension to the north of Josiah
Tongogara Avenue. Since then, the spread of the species outside Harare has been surprisingly slow. The specimen in the image appears to be the first record for the Southern Division.
