can Matricarias are relics of the temperate flora of that vast 
antarctic continent now vanished, where the genus was probably 
from their boreal relatives, for so fae as we know, no species has as 
yet been gathered on those lofty East African mountains which have 
a few representative species of certain genera otherwise confined to 
the northern hemisphere. (See Engler in Ann. Bot. xviii. 523-540.)

Zambesi, Hildebrandt ; Peters; Zambesi delta between Mambusha and 
Vicénte, Sept., Scott ; open woods at Beira, Dec., Swynnerton, 1872. 
I have not seen the type specimen collected by Hildebrandt, but 
piss seems little doubt that Scott’s and Swynnerton’s plants belong 
this species, judging from Vatke’s description.
