中文摘要 | 本文描述了中國湖南西北部產蒲兒根屬一新種:吉首蒲兒根(Sinosenecio jishouensis D. G. Zhang, Y. Liu & Q. E. Yang)。本新種以具莖生葉,葉橢圓狀披針形,葉脈羽狀,瘦果無冠毛而與同屬其他種類明顯有別。其體細胞染色體數目為2n=48和96。本文提供了吉首華千里光的彩色圖版、線繪圖、花部微觀性狀的光鏡照片以及地理分佈圖。 |
英文摘要 | Sinosenecio jishouensis D. G. Zhang, Y. Liu & Q. E. Yang, a new species from north-west Hunan, China, is described and illustrated. This new species is easily distinguishable from all its congeners by having leafy stems, broadly elliptic-lanceolate and pinnately-veined leaves, and achenes without a pappus. Its somatic chromosomes were counted as 2n = 48 and 96. A color plate, line drawings, light microscope (LM) photomicrographs of floral microcharacters, and a distribution map are given for the new species. |
