摘要
对新种右旋过路黄LysimachiadextrorsifloraX.P.Zhang,X.H.Guo&J.W.Shao进行了描述和绘图。该新种产于中国安徽和福建,因茎匍匐,叶对生,花黄色,单生叶腋与过路黄L.christinaeHance近缘,但其花冠裂片在蕾期右旋(顺时针)旋转排列(俯视),花梗通常长于叶片与叶柄长之和,花期4月初至5月初而不同。
A new species of the genus Lysimachia, L. dextrorsiflora X. P. Zhang, X. H. Guo ＆ J. W. Shao, is described and illustrated. This species, occurring in Anhui and Fujian provinces of China, is similar to L. christinae Hance in the prostrate stem, opposite leaves, yellow flowers born singly in leaf axils, but differs by having corolla lobes contorted towards the right and imbricate in the bud from a top view, the pedicel usually longer than the subtending leaves, and the flowering time from early April to early May. In L. christinae, the corolla lobes are contorted towards the left from a top view, the pedicels are usually shorter than the subtending leaves, and the flowering time from early May to early June.
