Abstract
The new species Crepidorhopalon droseroides from Mozambique is described and illustrated. It represents the third strict Mozambique endemic in Linderniaceae, and it differs from all known species of Crepidorhopalon in the long sticky glandular hairs. The hypothesis that the species may be carnivorous is discussed. The Conservation Status is preliminarily assessed.
