| (1)确定rhizome的中文译名“根状茎”符合此术语的定义,同时认为另一中文译名“根茎”不符合有关定义,且易引起误解,应予废弃。(2)介绍了在中国植物学文献中稀见的2种属于有限花序类的花序类型,有限伞形花序和有限头状花序。根据有关欧美专家的花序研究,介绍了在中国植物学文献中放在无限花序类的隐头花序和柔荑花序系由聚伞花序演化而出,而应属于有限花序类的论断; 同时,作者提出楼梯草属梨序楼梯草组的雄隐头花序系由同属的骤尖楼梯草组的有限头状花序演化而出的论点。 |

| Abstract: |
| (1)The Chinese translation of the term“rhizome”is discussed,and the correct translation is ascertained.(2)Two inflorescence types,determinate umbel and determinate capitulum,rarely known in Chinese botanic literature,are introduced. On the basis of the studies of inflorescence conducted by various botanists it is clear that both hypanthodium and catkin evolved from the cymose inflorescences,and should belong to determinate inflorescence,rather than to indeterminate inflorescence. The staminate inflorescence of Elatostema sect.Androsyce(Urticaceae)with urceolate receptacle is also recognized to be a hypanthodium,and may be derived from the determinate capitulum of Elatostema sect.Elatostema. It differs from the hypanthodium of the genus Ficus(Moraceae)in having no basal and oral bracts and in its receptacle divided before the bloom of the staminate flowers. |
