本文描述寮國南部山奈屬 (薑科) 新種－Kaempferia champasakensis Picheans. &
Koonterm.，並提供圖片。此一新種可以藉由純白的花、其唇瓣裂至基部三分之二以及卵狀橢圓形至近圓形之大型白色花藥附屬體等特徵易於鑑別，與其他分類群的關係也一併予以討論。

A new species of Kaempferia L. (Zingiberaceae) from Southern Laos, K. champasakensis,is described and illustrated. This new taxon can be easily recognized by its pure white flowers with the labellum divided two-third to the base and the large white ovate-elliptic to suborbicular anther crest with greatly varied apex. Relationship with other taxa is also discussed.
