In Taiwan, Ricinus communis L. is a cultivated and naturalized plant of Euphorbiaceae, with a complex inflorescence. This monoecious plant has female flowers on the upper part of the inflorescence and male flowers on the lower. The spike of the inflorescence consists of dichasia. The early development of both female and male flowers are similar, however they differentiate after initiation of gynoecium and androecium primordia. We observed some unusual structures within the female flowers in this monoecious plant. These tiny structures initiate and grow around the base of ovary and they are variable in shape and size. Some stamen-like structures were recognizable when the gynoecium differentiated into stigma, style and ovary. These staminodes were examined and compared with the stamens in male flowers by using electron microscopy and light micorscopy.
