八角属植物分类

根据对18个国家和地区121个标本馆收藏的万余份八角属植物标本研究，结合在国内8个省区野外调查，采集，引种和对生长发育与物侯的观察，本文对世界性八角属植物做了分类学修订，根据花蕾和花片形态特征的，将八角属分为2组：八角组－含9种1亚种，其花勒卵球形，花被片长圆形，椭圆形，披针形至狭舌状，扁平；八角茄香组－含25种2亚种1变种，期 花勒球形，花被片长圆形，椭圆形，披针形至狭舌状，扁平；八角茴香形－2含25种2亚种1变种，其花蕾球形，花被片宽卵形至圆形，下凹，将凹脉组作为八角组的新异名，圆被亚属作为八角茄香组的新异名；指定了红茴香和柬博寨八角的后选模式。本文还分析了八角属植物的分类学性状，作出有分类检索表，提供有各种植物的地理分布资料，列举出查阅的主要标本，并对各分类单元均作了分类学注释。

Taxonomy of the Genus Illicium Linn.

A taxonomic revision of the genus Illicium is presented based mainly of herbarium studies involving more than 10 thousand speciemens from 121herbaria worldwide, along with field observations and morphological studies. Variation in morphological character of flower buds and tepals is used as the basis of an amended supraspecific classification, with 2 sections, viz.: Illicium sect. Illicium , consisting of 9 species and 1 subspecies and characterized by flower buds ovoid, and tepals oblong, elliptic, lanceolate to narrowly ligulate, and flat; and Illicium sect. Cymbostemon, consisting of 25 species, 2 subspecies and 1 variety with flower buds sphaeroid, and tepals broadly ovate to orbicular, and concave. Illicium sect. Impressicosta Law & Q. Lin is regarded as a new synonym of Illicium sect. Illicium, Illicium subgen. Cymbostemon (Spach) Law & Q. Lin is regarded as a new synonym of Illicium sect. Cymbostemon (Spach) A. C. Smith, and lectotypes of Illicium henryi Diels and I. cambodianum Hance are designated. Taxonomic character, a key to the taxa, geographical distribution, specimens examined, and classification notes are provided for each taxon in this paper.
