珍珠菜属的新组合和新异名──兼论此属植物在中国和日本的地理替代现象

Based on an examination of specimens now available from China and Japan, Lysimachia tashiroi Makino was reduced to L. patungensis Hand-Mazz. as synonym; L.tanakae Maxim. was treated as a subspecies of L. christinae Hance. The distribution and geographical vicariism of this genus between China and Japan were also discussed.
