Abstract

In the course of taxonomic studies on Zingiberaceae in Myanmar, a new species of Curcuma assignable to subgenus Ecomatae was discovered in Htamanthi Wildlife Sanctuary, Sagaing Region, northwestern Myanmar. It is described and illustrated here as Curcuma stolonifera. This new species differs from other species in subgenus Ecomatae Škorničk. & Šída f. in having a combination of the following characters; long creeping rhizomes, an oblong-lanceolate lamina with reddish midrib, a small number of green bracts, a central inflorescence, pale whitish yellow flowers, and a short slightly L-shaped anther with a curved spur.
