| 摘 要： | 研究了产于西伯利亚的西伯利亚嵩草Kobresia sibirica (Turcz.ex Ledeb.) Boeck.,产于北美的K.hyperborea Porsild和K.macrocarpa Clokey。三者之间无显著差异,并且它们的雌花都具有由一至三枚小鳞片组成的花被。因此,它们为同种植物, K.hyperborea包括其变种var.alaskana Duman和var.lepagei Duman及K.macrocarpa被降为西伯利亚嵩草的异名。西伯利亚嵩草分布于亚洲和北美洲的北极和亚北极地区,可能起源于亚洲,由东西伯利亚通过白令海峡散布到北美。

| Abstract: | Kobresia sibirica (Turcz. ex Ledeb.) Boeck. from Siberia, K. hyperborea Porsild and K. macrocarpa Clokey from North America were studied. There are no significant differences among the three species, and their female flowers are all provided with a perianth of one to three small scales. Therefore, they are conspecific. Kobresia hyperborea, including varieties alaskana Duman and lepagei Duman, and K. macrocarpa are reduced to synonyms of K. sibirica. The species is distributed in the arctic and subarctic Asia and NW North America. It might have evolved in Asia, and migrated from eastern Siberia through the Bering Strait to North America. |
