Etlingera comosa Ardiyani & Ardi, a new and unusual species from Tentena, Central Sulawesi exhibiting terrestrial as well as epiphytic habit is described here. It is compared to the morphologically closest Etlingera sublimata A.D.Poulsen, but differs in having tufted sheath, bilobed and asymmetric ligule, loose peduncular bracts, densely pubescent fertile bracts and longer filament. Colour plates, notes on its conservation status and DNA barcode data for the new species are also provided.

Etlingera comosa Ardiyani & Ardi spec. nov.
Similar to Etlingera sublimata A.D.Poulsen by the spiny bracts and thecae dehiscent through their entire length but E. comosa differs from E. sublimata in having tufted sheath (vs. not tufted), bilobed, asymmetric ligule (vs. entire), peduncular bracts only loosely enclosing base of spike and partly exposed the axis (vs. peduncular bracts enclosing base of spike, peduncle axis not exposed), fertile bracts densely pubescent (vs. glabrous with ciliate margin), longer stamen (9 mm vs. 5 mm), longer filament (3.5–4.5 mm vs. 0.5 mm) and shorter anther (4 mm vs. 5–5.5 mm).
Etymology. The epithet comosa refers to the
tufted hairs of the sheath.
