Zingiber nitens M.F.Newman, sp. nov. Belongs to Zingiber section Dymczewiczia (Horan.) Benth. because the inflorescences are produced terminally on the leafy shoots; similar to Zingiber capitatum Roxb. in its slender habit with narrow leaves and terminal inflorescences but differs from it by its glabrous, glossy, dark green bracts which remain green even at fruiting (not green bracts which turn red at fruiting, and are sparsely to densely villose at the margins).

Distribution & ecology. Zingiber nitens is only known from the type locality, where it grows in primary evergreen forest along a river at c. 570 m altitude.

Etymology. The epithet “nitens”, Latin for shining, refers to the shiny bracts of the inflorescence.
