S . Nuraliev 1624 ( IBSC ; MW : MW0754511 ) . Notes. Lysimachia nutantiflora is described as having an elongate several- to many-flowered terminal raceme, which is an important character for identification of this species ( Hu & Kelso 1996 ). However, the flower-subtending bracts of L. nutantiflora are leaf-like, with the lower bracts differing from the leaves only in being twice smaller (sometimes even insignificantly smaller, as seen in the Vietnamese specimen). Thus, L. nutantiflora shows an intermediate morphology between a terminal raceme and solitary flowers in axils of the upper leaves.
