Abstract
The pollination biology of Crassula fascicularis Lam. (Crassulaceae) w as studied at Bain's Kloof, South Africa. No diurnal visitors to the f lowers were observed, but geometrid moths carrying C. fascicularis pol len on their proboscides were caught in a light trap between 20:30 and 04:00. Nectar is secreted in the afternoon and evening, reaching a ma ximum volume when the moths are active. Scent production almost ceases at midday and then gradually reaches peak intensity around midnight. The floral features of C. fascicularis are compared with those of the related species Crassula coccinea L. which is pollinated by butterflie s.
