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, 5–15 mm long, concealed in leaf sheaths, corolla tubes longer, 10–12.5 cm long, labellum 2-lobed with each lobe further 2-lobulate. 相似文献

Abstract Hedychium menghaiense X. Hu & N. Liu, a new species of the Zingiberaceae from Yunnan Province, China, is described and illustrated. The new species is currently known only from its type locality, Nannuoshan Mountain, Menghai County, growing under evergreen broad‐leaved forests at altitudes of 1400–1700 m. It is similar to Hedychium forrestii Diels, but differs in its narrower and emarginate labellum folded inwards lengthwise, narrower staminodes, and scarlet stamen. The recognition of the new species is supported by the results from analysis of sequence‐related amplified polymorphism markers. 相似文献
