The present paper deals with the infrageneric classification, phylogeny and geographic distribution of the genus Lomatogonium. A cladistic analysis was undertaken to establish the taxa and to evaluate the relationships between the taxa. The PAUP computer program was used in this analysis. The most parsimonious tree (Cladogram) of the rotate-corolla group of subtribe Gentianinae shows that Lomatogonium is closely related to Lomatogoniopsis and Swertia, but distantly to Veratrilla. Among them, Swertia is more primitive than Lomatogonium and hence Sect. Swertia was selected as the outgroup to polarize the character states of ingroup (Lomatogonium). A data matrix of 29 charaters of Lomatogonium was made for constructing the cladogram. Two most parsimonious trees were formed one of which, with the lowest f value, was at last selected as a shortest tree. In this tree 18 species fall into three groups, i.e. Sect. Sarcorhizoma, Sect. Lomatogonium and Sect. Pleurogynella. The former comes at a lower level with more plesiomorphies while the latter at a higher level with more apomorphies. Lomatogonium is distributed in the northern temperate zone. However, 16 species are centred in Asia and two extend to Europe, or further to the Arctic region, but none has been found from Africa, Australia and South erica. The analysis of distribution pattern of species shows that the Qinling-Hengduan Mountain region is both the frequence and diversity centers of Lomatogonium. From the cladogram of Lomatogonium (Fig. 5 ), L. perenne appears to occupy the most plesiomorphic node. This is an indication that it is the extant species closest to the ancestral form and it also implies that the ancestral species may reside in the habitat of this species (the Qinlin-Hengduan Mountain region). On the other hand, a umber of species of Swertia Sect. Swertia also occur in this region today, which indicates that the Qinlin-Hengduan Mountain region may well be the original center of Lomatogonium. From the distribution pattern of L. rotatum, it can be concluded that the time of the origin dates back at least before the Pliocene. After emergence, this genus had first developed and dispersed in the original center and adjacent region, then diverged into two lineages. One gave rise to the widespread species (northern temperate distribution species L. carinthiacum and L. rotatum), and the other formed the Himalayan species.A taxonomic revision of the whole genus Lomatogonium is presented. In this paper, one new section (Sect. Sarcorhizoma), one new species (L. zhongdianense S. W. Liu et T. N. Ho) and one new variety (L. forrestii var. densiflorum S. W. Liu et T. N. Ho) are described. The key to the species is given. Type studies are made for all the taxa.  相似文献

四川乌头属的修订   总被引:4,自引:0,他引:4  
四川是我国乌头属Aconitum L.植物的重要分布区。本文对该地区的乌头属植物进行了分类修订。通过文献查阅、野外观察和标本室研究,对乌头属的形态性状在居群间和居群内的变异式样进行了比较分析,发现叶分裂程度、上萼片的形状和花梗毛被等性状是较为可靠的分种依据,但是在个别情况,这些性状也会在同一种的同一居群内或不同居群间发生变化。花瓣和种子的特征对于属下划分有重要意义。本文承认四川乌头属植物有46种11变种,另有2种和1变种暂存疑。29种和22变种降为异名;作出新组合2个,其中包括1个改级新组合。紫乌头A. delavayi Franch.和保山乌头A. nagarum Stapf为四川新分布记录。对康定乌头A. tatsienense Finet &; Gagnep.、川鄂乌头A. henryi Pritz.和狭裂乌头A. refractum (Finet &; Gagnep.) Hand.-Mazz.进行了后选模式的标定。初步澄清了东俄洛乌头A. tongolense Ulbr.和狭裂乌头等种类中长期存在的名实混乱。还给出了各个种的形态描述、地理分布以及分亚属、分系和分种检索表。  相似文献
