Abstract
Exochaenium clavatum subsp. stella-palustre is here described as a new subspecies from Zambia. It is characterized by its relatively small size (20 cm tall), leaves massed at the base of the stem and oriented downwards, a single, bright yellow flower, and a calyx wing broadest at the middle. Furthermore, this new taxon was collected in a dambo, in contrast to the inundated lakeshores where E. clavatum subsp. clavatum typically occurs. A key distinguishing the two subspecies is provided.
