ABSTRACT
Newmania bambusifolia Škorničk., Vuong & Bao (Zingiberaceae:
Zingiberoideae), a new ginger species discovered in Hon Ba Nature Reserve, Khanh Hoa
Province in southern Vietnam is described and illustrated here with notes on distribution,
ecology, phenology, preliminary IUCN assessment, and etymology. It is distinct from all
known congeners by the very narrow leaf-blades, resembling those of bamboos. This discovery
increases the total number of species in Newmania to seven. We include an updated key to the
genus accommodating this novelty.
Keywords. Eastern Indochina, gingers, Khanh Hoa Province, Vulnerable, Zingibereae

Newmania bambusifolia Škorničk., Vuong & Bao, sp. nov.
Unique in the genus by its prominently narrow, bamboo-like leaf-blades and dark purple labellum with overlapping lobes. Flowers are most similar to Newmania cristata by the yellow to greenish floral tube and filament, but differ by having a small anther crest less than 1 mm long with entire rounded apex (vs anther crest 4.6–5 mm long with a bilobed apex).
Etymology. The specific epithet refers to the unusually narrow, bamboo-like leaf blades.
