中國四川產蒲兒根屬一新種：藝林蒲兒根
摘要
本文描述了中國四川產蒲兒根屬一新種：藝林蒲兒根(Sinosenecio yilingii Y. Liu & Q. E. Yang)。本新種與腎葉蒲兒根 [Sinosenecio homogyniphyllus (Cumm.) B. Nord.] 相似，但以植株較高，葉基生以及莖生，通常腎形，偶爾闊卵形，葉片上表面無毛或稀被柔毛，葉柄基部與花序梗上部密被絲狀毛，頭狀花序單生，總苞片11-13而與後者相區別。其體細胞染色體數目為2n = 60。核型公式為2n = 56 m +4 sm。本文提供了藝林蒲兒根以及腎葉蒲兒根的彩色圖版、藝林蒲兒根的線繪圖、花部微觀性狀的光鏡照片以及地理分佈圖。
並列摘要
Sinosenecio yilingii Y. Liu & Q. E. Yang, a new species from Sichuan, China, is described and illustrated. The new species is similar to S. homogyniphyllus (Cumm.) B. Nord., but differs in the taller stature, the leaves radical and cauline, often reniform, occasionally broadly ovate, glabrous or very sparsely pubescent above, the petioles proximally and the peduncle distally densely sericeous, the capitula solitary and terminal, and the phyllaries 11-13. Its somatic karyotype is formulated as 2n = 56m + 4sm, giving a chromosome number of 2n = 60. Photographs of both S. yilingii and S. homogyniphyllus, line drawings, distribution map, and light microscope (LM) microphotographs of floral characters of S. yilingii are provided.
