对中国伞形科变豆菜亚科 (Saniculoideae) 2属 (变豆菜属Sanicula L .和刺芹属Eryngium L .) 13种植物的果实形态结构进行了比较解剖学观察 ,从果实横切面形状及其合生面宽度、外果皮和中果皮外突所呈皮刺和鳞片或瘤状体的形态及皮刺中木化厚壁细胞组织的分布、外果皮细胞形状及其角质层厚度、中果皮细胞层数和结晶体类型及分布、色素块沉积、伴生分泌管和油管的大小及分布等方面对上述各属种进行了观察和分析 ,归纳出各属的果实解剖特征 ,探讨了属间演化水平 ,认为刺芹属果实较变豆菜属果实演化程度高。结合已有的研究结果 ,讨论了该亚科与伞形科天胡荽亚科 (Hydrocotyloideae)间的区别及其演化关系。

The comparative anatomical characters of the fruits of 13 species belonging to 2 genera ( Sanicula L. and Eryngium L. ) in Saniculoideae distributed in China was reported. According to the shape of mericarp in transection and the width of commissure, covered with aculei, scales or tubercles on peel, whether or not to have lignified cell layers in aculei, the cell shape of exocarp and cuticle thickness, the numbers of cell layers, the morphology and distribution of crystals and whether or not to have pigment granule in mesocarp, as well as the size and distribution of companion secretory canals and oil tubes, combining with the external characters, the distinctions and evolutionary relationships between Sanicula L. and Eryngium L. were discussed. It is suggested that the fruit evolutionary degree of Eryngium L. is higher than that of Sanicula L. The distinction of fruit anatomical characters and evolutionary relationship between Hydrocotyloideae and Saniculoideae were also discussed.
