| 中文摘要 | 本文報導產於中國廣西的小檗科十大功勞屬 (Mahonia) 植物一新種靖西全緣葉十大功勞 (Mahonia jingxiensis),該新種的區別特點、描述、詳細插圖、彩圖和分類評述被給出。把該新種與其他3 個相似 (Mahonia shenii and M. microphylla) 或產地相近 (M. subimbricata) 的種進行了比較。但M. jingxiensis 與其他3 個種不同在於該新種具小葉5-7 對,小葉較大,全緣,上面脈明顯凸起,最下面一對小葉較小 (0.5-3 × 0.3-1.5 cm) 且到葉柄基部的距離較短 (約1 cm),總狀花序有時分枝,中萼片 (3.7-4.1 × 1.9-2.1 mm) 與內萼片 (4.1-4.3 × 2.2-2.5 mm) 幾乎等大;漿果梨形,較小 (3.5-5 mm) 該新種的花粉和種子形態被報導。 |
| 英文摘要 | Mahonia jingxiensis (Berberidaceae), a new species from Guangxi Zhuangzu Autonomous Region, China, is described. Its distinguishing characters and description are given, along with a detailed illustration, color photographs, and taxonomic comments. The species is compared with two similar species (Mahonia shenii W.Y. Chun and M. microphylla Ying et G.R. Long) and a species (M. subimbricata W.Y. Chun et F. Chun) from adjacent locality in the genus. The species is distinguishable from the three species in having big entire leaflets, distinct adaxial venation; the lowest pair of leaflets is small (0.5-3.0 × 0.3-1.5 cm) and situated a short distance (ca. 1 cm) from the petiole base; racemes are sometimes branched, middle sepals (3.7-4.1 × 1.9-2.1 mm) and inner sepals (4.1-4.3 × 2.2-2.5 mm) almost equal; berry pyriform, small (3.5-5 mm). Its pollen and seed morphology are reported. |
