ABSTRACT	A new species of Lysimachia, L. chingshuiensis C.-I Peng & C. M. Hu, from Taiwan is described and illustrated. This species is found on the gravelly summit of Chingshuishan, a metamorphosed limestone mountain in Taroko National Park, ca. 2,200_2,400 m in elevation. It is very rare, presently known only from the type locality. Lysimachia chingshuiensis is a distinct species in sect. Nummularia (Gilib.) Klatt., somewhat similar to L. deltoidea Wight of NE India, Sri Lanka and SW China, but distinct in its subsessile, subcoriaceous leaves with revolute margins, and flowers subsessile, solitary in the axils of the uppermost leaves. A key is provided to aid in the identification of the ten species of Lysimachia indigenous to Taiwan.
