Abstract

Color of pollen grains of Chrysosplenium album Maxim. (s.l.) in vital conditions were yellow from Fukushima Pref. to north-east Gifu Pref., while those were white from south-west Gifu Pref. to Miyazaki Pref. These results are geographically so stable that color of pollen grains is valuable for diagnostic character between C. album var. album (white) and var. stamineum (yellow). Boundary area between var. album and var. stamineum is probably located around Gujo-shi, Gifu Pref., concordant with Wakabayashi(2001)'s recognition.
