深入研究了当归属及其相关7属，古当归属，高山芹属，柳叶芹属，独活属，欧当归属，山芹属及前胡属毛状体和果实结构。结果显示毛状体及果实结构（如：毛状体细胞，翅，油管，维管束，中果皮，内果皮，结合面及结晶）可以用于区分当归属及其相关类群。滇南当归及隆萼当归应从当归属移入独活属，其余当归属物种分为结合面宽及结合面窄两组，前者与前胡属较为相似，但与独活属差别较大，后者与古当归属，高山芹属，柳叶芹属，欧当归属有相似之处。支持分子系统学揭示的当归属不是个自然类群，当归属与前胡属共同位于当归分支，而独活属位于独活分支。山芹属果实结构与其他属不同，翅的中果皮无细胞，且伴生油管位于维管束内侧，为分子系统学显示此属与高山芹属，柳叶芹属，及欧当归属亲缘关系较远提供了形态学依据。
深入研究瞭噹歸屬及其相關7屬，古噹歸屬，高山芹屬，柳葉芹屬，獨活屬，歐噹歸屬，山芹屬及前鬍屬毛狀體和果實結構。結果顯示毛狀體及果實結構（如：毛狀體細胞，翅，油管，維管束，中果皮，內果皮，結閤麵及結晶）可以用于區分噹歸屬及其相關類群。滇南噹歸及隆萼噹歸應從噹歸屬移入獨活屬，其餘噹歸屬物種分為結閤麵寬及結閤麵窄兩組，前者與前鬍屬較為相似，但與獨活屬差彆較大，後者與古噹歸屬，高山芹屬，柳葉芹屬，歐噹歸屬有相似之處。支持分子繫統學揭示的噹歸屬不是箇自然類群，噹歸屬與前鬍屬共同位于噹歸分支，而獨活屬位于獨活分支。山芹屬果實結構與其他屬不同，翅的中果皮無細胞，且伴生油管位于維管束內側，為分子繫統學顯示此屬與高山芹屬，柳葉芹屬，及歐噹歸屬親緣關繫較遠提供瞭形態學依據。

Trichomes and fruit structures of Angelica and seven related genera (Archangelica,Coelopleurum, Czernaevia,Heracleum,Levisticum,Ostericum,and Peucedanum)were studied.Differences in the trichome and fruit structures (e.g.wing,vitta,vascular bundle,mesocarp,endocarp,commissural side,and crystals) were found to provide useful characters to distinguish between Angelica and related taxa.Angelica austro-yun-nanensis and A.oncosepala should be moved to the genus Heracleum,and other taxa of the Angelica group could be divided two groups,one with a wide and the other narrow commisure.In the former the fruit struc-tures of the taxa are similar to those of Peucedanum,and differ from those of Heracleum and in the latter they are similar to those of Archangelica,Coelopleurum,Czernaevia,Levisticum,and Ostericum.This study sup-ports the findings from molecular research that as currently defined the Angelicaceae is not a natural group. Angelica and Peucedanum should be placed in an Angelica clade and Heracleum in a Heracleum clade.The fruit structures of Ostericum differ from the other genera in the wing without mesocarp cells,and the rib duct presenting inside of the vascular bundles.On this evidence,the genus Ostericum is not very close to the genera Coelopleurum,Czernaevia,and Levisticum.
