Diagnostic description

Ezosciadium capense is a highly distinctive species, easily distinguished from all other annual species by the pilose vegetative and reproductive organs, the sessile compound umbels with a few, markedly unequal rays, the non-inflexed petal tip, the relatively small, highly inflexed stamens which appear almost sessile, and the prominent bifid carpophores, one half of which persists on the plant.

Distribution

This poorly collected species is endemic to the Eastern Cape Province of South Africa and is known from only four recorded populations, three of which have only come to light recently. Originally known only from Coega koppie near Uitenhage, the distribution range has been expanded to include Perdepoort (the westernmost locality), Joubertina and Bethelsdorp.
