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

NEW COMBINATION AND SYNONYM IN LYSIMACHIA(PRIMULACEAE) WITH REFERENCE TO GEOGRAPHICAL VICANIISM OF THE GENUS IN CHINA AND JAPAN

摘要:

本文对过去一直认为是日本特有的两种珍珠菜属植物作了归并和组合：将Ｌｙｓｉｍａｃｈｉａ，ｔａｓｈｉｒｏｉＭａｋｉｎｏ归并作Ｌ．ｐａｔｕｎｇｅｎｓｉｓＨａｎｄ．－Ｍａｚｚ．的异名，将Ｌ．ｔａｎａｋａｅＭａｘｉｍ．降级作Ｌ．ｃｈｒｉｓｔｉｎａｅＨａｎｃｅ的亚种处理．对此间植物在中国和日本的地理替代现象作了讨论．

Abstract:

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.
