| 摘 要： | 运用多学科综合分类手段，研究了山芹不同产地居群的变异，发现分布于我国东北部的各居群与华东居群不但存在地理分布上的间断，而且在外部形态、果实及叶柄解剖、核型组成和生物学特性等方面也存在显著差异，因而华东的山芹各居群应独立出来完成一新种──华东山芹OstericumhuadongensisZ.H.PanetX.H.L。

| Abstract: | This paper elucidates the separation of a new species from Ostericum sieboldii (Umbelliferae) in China, i. e. Ostericum huadongensis Z. H. Pan et X. H. Li, based on the results of synthetic comparative taxonomic studies. The distinctive characters of the new species are described as follows: the shape of petioles triquetrous, the arrangment of vascular bundles in the transections of the petioles takes the form of "Y";the ultimate segments of leaves ovate to rhombic-ovate; inflorescences relatively less branched; vittae usually 1 in the vallecula, 2 in the commissure; in addition, O.huadongensis is mainly distributed in East China. |
