NATTAPON NOPPORNCHAROENKUL, THAYA JENJITTIKUL

Abstract


Kaempferia noctiflora, another precocious flowering species of Kaempferia subgen. Protanthium (Zingiberaceae) from Northern Thailand is described and illustrated. Pure white flowers with nocturnal anthesis and a tinged purplish red patch along the midvein of the upper surface of the leaves are the unique characters of this new taxon. The morphological characters of K. noctiflora are compared to closely related species and a key to Thai precocious flowering Kaempferia species is also provided.
