Shoots with three-whorled leaves are formed at the base of previous shoots. Shoots with opposite leaves are sometimes formed at the base of previous shoots as well as leaf axes. When shoots with opposite leaves are formed at the base, the stem of opposite shoots is thinner than that of three whorled shoots. As the number of floral organ depends on the meristem size (Kitazawa and Fujimoto 2015), the difference of leaf number in a whole may be caused by the difference of meristem size.<\/p>\n
