Zingiber kelabitianum(Zingiberaceae): a new species from Borneo

Abstract

Sm. in the large size of the plant and the robust, cylindrical inflorescences with deflexed bracts. It differs in the dense, yellow-brown indumentum of the leaf sheath and ligules, the bright red bracts, the longer bracteole and the free, well-developed lateral lobes of the labellum. The traditional uses of the plant by the indigenous people, the Kelabits, are described.
