Notes on the floral biology and pollination syndrome of Echinopsis chiloensis (Colla) Friedrich & G.D.Rowley (Cactaceae) in a population of semiarid Chile
We report some aspects of the floral biology ofEchinopsis chiloensis ssp. chiloensis in a population near to the northern limit of its distribution. Anthesis is strictly diurnal and flowers remain open during 492 min on the average. Echinopsis chiloensis is self-incompatible. Flower longevity, necta...
