A study of 3 Ceratoides species for their flowering habit, daily flowering dynamic change, fertility, and stigma micromorphology shows that the male flowers of C.arborescens and C.latens reach their full bloom at 8:00-10:00, while the male flowering peak of C.lanata falls on 11:00-13:00. The bloom peak of the female flowers of all 3 occur at 14:00. Though the most congenial temperature for flowering of all the 3 species is 20~24℃, the female stigma micromorphology of C.arborescens is best suited for gathering pollen than the other 2 species. Therefore, C.arborescens boasts the highest seed bearing rate. Moreover, the flowering period of C.arborescens and C.latens last longer than that of C.lanata , a fact which also results in the highest seed bearing rate of C.arborescens, and the lowest seed bearing rate of C.lanata .
