Abstract
A new species, Curcuma glandulosa P.P. Thwe, M.M. Aung & Nob. Tanaka, is described from Taunggyi, southern Shan State, Myanmar. The new species is assignable to Curcuma subgenus Ecomatae, characterized by its epigynous glands, anther spurs, and lack of a conspicuous coma of sterile bracts. Curcuma glandulosa is distinguished by its red leafy stems, white bracts with red stripes, L-shaped anther spurs with densely short glandular hairs throughout, and a prominent anther crest. The leaves develop after blooming.

Diagnosis. Curcuma glandulosa is similar to C. sahuynhensis; however, it is distinguished from it by a combination of the following characters: red leafy stems (vs. green), broadly lanceolate lamina developing after flowering (vs. ovate to elliptic and developing at the same time of flowering), white bracts with red stripes (vs. whitish to pale green at base with coral pink to red tinge), white anther (vs. yellow), and having prominent anther crest (vs. almost negligible).
Etymology. The specific epithet “glandulosa” refers to its character of densely glandular anther.
