Abstract

The ecology, reproductive biology and hybridization of species in the genus Gaultheria (Ericaceae) has been investigated with particular reference to those species in Ecuador. Most species were found to be plants of disturbed ground particularly on roadside banks and forest margins. The species in Ecuador were not seen to be visited by potential pollinators although fruit set was high. No animals were seen to eat the fleshy fruits. Male sterile plants of many species from throughout the distribution of the genus were observed indicating a higher level of gynodioecism in the genus than previously thought. Empty anthers in two Ecuadorean species suggests that gynodioecism may be present in many species without any clear morphological change. A hybrid between Gaultheria myrsinoides and G. reticulata has been found in Ecuador.
