Reproductive Biology and Mating System Estimates of Two Andean Melocacti Melocactus schatzlii and M. andinus (Cactaceae)

摘要

Background and AimsThe genus Melocactus comprises 36 species of globose cacti with the most derived traits in the Cereeae tribe. It is the proper study system to examine what are the most derived reproductive strategies within that tribe. This study aims to characterize the reproductive biology and to estimate the mating system parameters of two Andean melocacti, Melocactus schatzlii and M. andinus.
