中文摘要 | 本文描述和圖解桔梗科風鈴草屬一新種,甘肅風鈴草 (Campanula gansuensis),依據對中國產風鈴草屬 21 個分類群的地理分布和主要特徵分析,確定該新種的系統位置。甘肅風鈴草屬於風鈴草組 (sect. Campanula),其萼片間具附屬物的特徵略似紫斑風鈴草 (C. punctata) 和刺毛風鈴草 (C. sibirica),但甘肅風鈴草為一年生,植株約 6 公分高,花冠綠色明顯可以區別。現僅知甘肅風鈴草分布於秦嶺西段南坡的甘肅徽縣麻沿河海拔 1,100 公尺山谷中。本文並將風鈴草屬在中國產的 22 個分類群編制成分種檢索表,以助鑑定。 |
英文摘要 | In this paper, a new species of Campanula, C. gansuensis L.Z. Wang et D.Y. Hong from Gansu is described and illustrated. According to an analysis of the distribution and main characters of 21 taxa of Campanula indigenous to China, C. gansuensis is a distinct species in sect. Campanula. Based on the reflexed appendage in each sinus of the calyx, it is somewhat similar to C. punctata Lam. and C. sibirica L., but differs in its annual habit and small green corolla. It is very rare and only found in Mayanhe, a village in the mountains of Hui Xian, in the West Qinling mountains of Gansu province, at ca. 1,100 m elevation. A key is provided to aid in the identification of the 22 taxa of Campanula in China. |
