Vernonia africana ((Sond.) H. Rob.)
|syn. Cacalia africana (Kuntze), Vernonia vernonella (Harv.)|
South Africa: Kwa Zulu-Natal
|local name: -|
extinction date: (?)
|The African Ironweed comes
from the South African province of KwaZulu-Natal, where the species was
last found near Mount Edgecombe, a town north of Durban, which, again, is
the third largest city in South Africa.
The species disappeared after its habitat had been converted for agricultural use, resp. was destroyed by urbanisation.
The genus Vernonia in the proper sense containes about twenty species, all of which occur almost exclusively on the North American continent, that means that the four species, mentioned here, should be assigned to other genera, which, however, are not known to me yet.
