东亚和北美当归属（广义）的果实解剖和演化

应用比较解剖研究了广义当归属在世界主要分布区－东亚和北美种类的果实结构的特征。根据分生果背腹压扁的程度、棱翅与槽的形状、果皮层次和结构、油管数目、大小和位置等稳定性状，可将果实分为５个类型，与《中国植物志》将其分为５个属，即古当归属，当归属，高山芹属，柳叶芹属和山芹属的意见相一致。古当归属为原始的类型，山芹属具有高度演化的特征。且对一些种类有分类位置提出了调整的意见和各属的演化趋势。

ON THE FRUIT ANATOMY OF ANGELICAL.(S.L. )OF EAST ASIA AND NORTH AMERICA AND ITS EVOLUTION

By means of comparative anatomy of Angelica L.(s.l.)of East Asia and North Americaspecies,the fruit structure was studied.The dorsal compressed degree of mericarps,charactersof the ribs and wings as well as their valleculae the pericarp structure, the position, diameter andnumber of vittae,etc. are distinctive and constant,those criterion can be used to separateAngelica(s.l.) fruit into five types,the classification of five genera in Flora Sinica,namely,Archangelica Hoffm.,Angelica L Coelopleurum Ledeb,Czernaevia Turcz. and OstericumHoffm,will further be supported. The systematic position of Co. gmelinii (A. lucida)andsome other species were disctissed.The hypothetical evoltitionary trend shows that Archangelicamay be at more primitive rank,while Ostericum is derived.
