摘要: 描述了中国云南姜科Zingiberaceae一新种——苍山象牙参Roscoea cangshanensis M. H. Luo, X. F. Gao & H. H. Lin。该种与大理象牙参R. forrestii Cowley在体态上相近, 但唇瓣深裂成2裂片, 每个裂片再2裂, 基部收缩成具白色条纹的柄, 叶片较狭窄,(2–)7–24×1.5–2.5 cm, 叶片基部狭缩成叶柄状而不同。该新种叶片基部狭缩成叶柄状, 唇瓣倒卵状楔形, Roscoea cangshanensis M. H. Luo, X. F. Gao & H. H. Lin, a new species of the Zingiberaceae from Yunnan, China, is described and illustrated. The new species is related to R. forrestii Cowley in habit, but differs in having 2-lobed labellum, each lobe 2-lobulate, base narrowed to a stalk with white lines, and narrower leaf blade, (2–)7–24×1.5–2.5 cm, with base narrow to petiole-like. The new species is also similar to R. debilis Gagnep. in having leaf base narrow to petiole-like, labellum obovate-cuneate, 2.5–3.5×2.5–3.0 cm, with white lines at throat, but differs in having bracts non-tubular, shorter, 5–
