摘要

Sexual characters of Chionographis chinensis Krause were examined on the basis of herbarium specimens. Of the 22 plants (on13 sheets) from southern China,18 were hermaphroditic, andromonoecious or male, and four were female. Each of the females was included together with at least one or two, non-female plants (hermaphroditic or andromonoecious plants) in collections from four localities in Guangdong and Guangxi. These facts indicate that C. chinensis is gynodioecious at least at the four localities.As compared with hermaphroditic or male flowers, the female flowers have vestigial stamens with shorter filaments and smaller indehiscent sterile anthers, and shorter tepals. The female and the hermaphroditic-andromonoecious plants both showed a high rate of fructification, although the sample size is small. This is the first record of the occurrence of gynodioecy in Chinese Chionographis.
