• Gynodioecy and floral dimorphism in Salvia omerocalyx Hayata, an endangered species endemic to central Japan, is here reported for the first time. In three populations of flowering individuals, one population had approximately equal numbers of hermaphrodites (= individuals only with perfect flowers) and male sterile individuals, another population was composed entirely of hermaphrodites, and the third was hermaphroditic except for two individuals with perfect- and male sterile flowers. Examination of herbarium specimens suggested two other localities with male sterile individuals. Male sterile flowers are significantly smaller than hermaphroditic flowers, but there was no difference in seed set between the two floral morphs. Additional field surveys are needed to determine the exact sex expression of the species.
