A Helosis (Balanophoraceae) from Costa Rica. Here are three flowering stalks (inflorencescences) of this species. The one at left is young, covered with polygonal structures that will fall off to reveal the flowers. The large inflorescence in the middle is covered with male flowers, some of which (white) are falling off. The inflorescence at right is covered with female flowers, which are much smaller than the male flowers. If you look closely, you will see a fly visiting the inflorescence in the middle, feeding on the sweet shiny droplets that occur on the male flowers.
