本文描述了泰国报春花科一新种--克拉登过路黄（Lysimachia kraduengensis）。它在形态上与L相似。恩格莱里湖lancifolia，L.拉克萨和L. sikokiana，花单生，腋生，花冠黄色，花梗较长，花药基着。根据高度、叶片质地、叶柄、花萼和花药长度以及花的棕色颜色，可以区分新种。此外，保护状况，更新的检索表在泰国的Lysimachia种，和讨论的系统放置的新物种的叶绿体DNA的trnL-F标记的基础上。
A new species of Primulaceae from Thailand, Lysimachia kraduengensis, is described and illustrated. It is morphologically similar to L. engleri, L. lancifolia, L. laxa and L. sikokiana in having solitary and axillary flowers, a yellow corolla, relatively long pedicels and basifixed anthers. The new species can be distinguished by the combination of its height, leaf texture, petiole, calyx and anther length, and brown coloration on the flowers. In addition, the conservation status, an updated key to Lysimachia species in Thailand, and discussion of the systematic placement of the new species based on the trnL-F marker of chloroplast DNA are provided.
