Function of Mentzelia nuda (Loasaceae) Postfloral Nectaries in Seed Defense
Mentzelia nuda is a coarse, short-lived perennial of the High Plains of North America. The flowers secrete nectar which serves as an attractant for pollinating bees. Postfloral nectar secretion attracts ants whose presence significantly enhances seed set. This is the first demonstration of advantage to postflowering activity of a floral nectary. RECENT STUDIES of nectaries that lie outside the ...
