| 摘要: |
| 头序赤车的特征在于其具花序托和总苞的雌头状花序,根据此一特征即可将它与赤车属的其它所有种区别开。因此,在2002年被错误归并为异名的此赤车属进化种,以及根据其建立的单种进化组头序赤车组在该文中予以恢复。 |

| Abstract: |
| Pellionia cephaloidea is characterized by its pistillate capitate inflorescences with receptacles and involucres,and by this one character it can be distinguished from all other species of the genus Pellionia. Thus,this curious advanced species and the advanced monotypic sect. Elatostematopsis based on it of the Pellionia,both erroneously relegated into synonyies in 2002,are restored in the present paper. |
