Zingiber porphyrochilum Y.H. Tan & H.B. Ding sp. nova (Zingiberaceae) from Yunnan, China is described and illustrated. It is similar to Z. densissimum in its bilobed ligule and flower shape but differs from it by having a longer clumped pseudostem (1.5–2.5 m tall vs. solitary, 0.4–0.7 m tall), longer ligules (3–11 mm long vs. ca. 3 mm long), brownish yellow corolla lobes (vs. pure white), labellum and lateral staminodes brownish yellow at the base, and bright clear red to dark purplish towards the apex and margins (vs. pure white).
