Abstract

A new monotypic genus, Tamijia (Zingiberaceae), and its species T. flagellaris are described from Sarawak, Borneo. T. flagellaris is quite unique with the lateral staminodes connate to the labellum, the plane of distichy of the leaf shoot transverse to the rhizome, long trailing inflorescences and ovary unilocular with parietal placentation. Although the species is placed in Alpineae based on the plane of distichy, it is quite distinctive from most of the species in the tribe in some other characters, and is important in considering the current system of tribes and genera of the family.
