重订羌活属的分类

在野外实地观察和标本整理的基础上，检查了羌活属各个分类群的分类问题，考证了它们的名 称。通过性状分析，主要以小总苞片的形状及其相关特征作为属下分类的依据，将卵叶羌活N．oviforme 改隶于宽叶羌活之下作为亚种处理，支持张盍曾在1975年将 N.franchetii  与N.forbesii合并为1种。如 此，该属共5种，其中1种含1亚种。描述了两个新组，对属的特征和地理分布作了补充。近年该属新增加2种，因此分种检索表也作了相应的修改。

A reclassification of Notopterygium Boissieu (Umbelliferae)

The genus Notopterygium is endemic to China. The plants of this genus are important traditional Chinese medicine. When established by H. de Boissieu in 1903, Notopterygium includ- ed only two species, i.e.N. franchetii and N. forbesii. Within nearly a century, five more spe- cific names had been added to this genus, i.e.N. forrestii H. Wolff, N. oviforme Shan, N. in- cisum Ting ex H. T. Chang, N. pinnatiinvolucellatum Pu et Y. P. Wang, N. tenuifolium Sheh et Pu. Based on field observation and examination of herbarium specimens, all the taxa in this genus were taxonomically reviewed and their nomenclature was carefully checked. N. oviforme was treated as a subspecies under N. forbesii. We agree with Chang He-Tseng in reducing N. franchetii to N. forbesii as a synonym. As a result, five species, one of which contains a subspecies, are recog- nized. Based on the morphology of involucel bractlets as well as their relevant characters, No- topterygium is divided into two sections.       Sect. 1. Notopterygium       Basal and proximal cauline leaves 2-ternate to 2 ～3-ternate-pinnate, ultimate divisions broad- ovate or ovate-lanceolate; involucel bractlets linear, entire, vascular bundles of petiole approximate- ly equal in size. This section contains two species and one subspecies.       Sect. 2. Tenuifolium Pu, sect. nov.       Basal and proximal cauline leaves 2 ～3-ternate-pinnate, ultimate divisions linear-lanceolate,ovate-lanceolate or linear; involucel bractlets linear, entire or oblanceolate, 2 ∽ 3-fid or pinnate at the apex; vascular bundles of petiole unequal in size. This section centains three species.
