Abstract
Zingiber latibracteum X.D.Ma, J.M.Lu & J.Y.Shen, currently assigned to Zingiber sect. Dymczewiczia, is newly described from Ha Giang Province, Northern Vietnam. It resembles Z. calcicola Y.H.Tan & H.B.Ding, Z. mellis Škorničk., H.Đ.Trần & Šída f. and Z. plicatum Škorničk. & Q.B.Nguyễn in having terminal inflorescences but is clearly distinguished by its glabrous ligules with rounded apex, shorter petiole, broadly elliptic bracts and smaller lateral staminodes. A comparison table of related species is provided.

Diagnosis: Zingiber latibracteum is readily distinguishable from Z. calcicola, Z. mellis and Z. plicatum by its glabrous ligules, rounded ligule apex, laminae without prominent plication, and shorter lateral staminodes (Table 1).
Etymology: The name ‘latibracteum’ from Latin latus (“wide”) and bractea (“bract”), indicating wide bracts in the species.
