• The preliminary observations on the self-sterility in Lilium Hansonii has been made with special reference to the pollen tube behaviors. 1) The number of somatic chromosomes is 2n=24, and the idiogram is shown in Fig.1. 2) The morphological normality of embryo-sac seems to be 100%. 3) The modes of pollen tube behaviors of some Lilium members in the pistils of L. Hansonii can be classified into two types : 1) stopps in the stylar part (L. Hansonii, L. rubellum), 2) stopps in the ovarian part (L. maculatum, L. concolor). 4) The pollen tubes of L. Hansonii stopps their growth in the stylar part of L. Henryi and of L. concolor. 4) The bud pollination gives some advantage to the pollen tube growth in the selfing.
