A Study on Dichocarpum (Ranunculaceae)

The genus Dichocarpum was established by W. T. Wang and Hsiao in 1964, who divided the genus into 2 sections: Sect. Dichocarpum including 10 species distributed on the mainland of E. Asia, and Sect. Hutchinsonia including 9 species native to Japan. M. Tamura and L. A. Lauener made a revision of the genus in 1968, who divided the genus into 4 sections, three for the species of the mainland of E. Asia, including 3 series and 10 species, and the other for the species of Japan, including 2 subsections, 3 series and 9 species. In the present paper, the genus is divided into 2 sections and 6 series, including 15 species and 3 varieties, and a putative phylogeny of the genus is proposed. The genus may be close to the genus Asteropyrum, and these two genera are rather specialized in Thalictroides (Ranunculaceae), because they have three very similar characters: the petal with a long claw, the stephanocolpate pollen and the chromosome morphology. The genus has 2n=24, 35(36?), which indicates that its basic number is X=6, and the species on the mainland of E. Asia (Sect. Dichocarpum) may well be paleotetraploids, whereas those in Japan (sect. Hutchinsonia) are paleohexaploids. Most of the advanced species are distributed in Japan and the most primitive ones in China and the Himalayas, the distribution pattern seggests that the Japanese members of this genus might have immigrated from China in the Tertiary, and differentiated and evolved there. The putative phylogeny of the genus is shown in Fig. 2 (at series level)     

Five new species of Triotemnus (Coleoptera, Curculionidae, Scolytinae) from Morocco and Yemen

Fivenew species of the genus Triotemnus from Morocco and Yemen are described. Triotemnus is a new genus of Scolytinae for the Yemen region. External morphology of the new species and all morphologically related species of the genus were studied. While the new species from Morocco are morphologically similar to the known species from the corresponding region, all three newly described species from Yemen, mainly two of them living in Socotra, are morphologically very different from all other known species of the genus. Geographical distribution and the probability of endemicity are discussed.     

六种鼠组织中过氧化物酶和酯酶变异的比较

本文研究姬鼠属（Ａｐｏｄｅｍｕｓ）２种鼠和鼠属（Ｒａｔｕｓ）４种鼠的心组织过氧化物酶和肝组织酯酶同工酶等位基因的变异。结果表明,６种鼠心组织过氧化物酶皆为４条区带,其中社鼠和白腹巨鼠的酶带泳动速度略快于褐家鼠和黄毛鼠的酶带;鼠属４种鼠的酶带间距大致相同,而姬鼠属的酶带间距略大于鼠属,这种谱型的区别就所分析的６种鼠而言,可以认为是该同工酶表现的属间区别。肝组织酯酶区带较多,其酶带数和泳动速度的差异具有明显的种间特征;泳动最快的酶带在姬鼠中是２条,在鼠属中是１条,可以认为是属间特征的区别。从９项生化指标的异同作动物配对比较,表明褐家鼠与黄毛鼠亲缘上较近,社鼠与白腹巨鼠亲缘上也较近,而且白腹巨鼠在进化上可能要比其余３种鼠属动物更接近于姬鼠属     

History and current taxonomic status of genus Agrobacterium

The genus Agrobacterium was created a century ago by Conn who included it in the family Rhizobiaceae together with the genus Rhizobium. Initially, the genus Agrobacterium contained the non-pathogenic species Agrobacterium radiobacter and the plant pathogenic species Agrobacterium tumefaciens and Agrobacterium rhizogenes. At the end of the past century two new pathogenic species, Agrobacterium rubi and Agrobacterium vitis, were added to the genus. Already in the present century these species plus Agrobacterium larrymoorei were reclassified into genus Rhizobium. This reclassification was controversial and for a time both genus names were used when new species were described. Few years ago, after a taxonomic revision based on genomic data, the old species A. rhizogenes was maintained in the genus Rhizobium, the old species A. vitis was transferred to the genus Allorhizobium and several Rhizobium species were transferred to the genus Agrobacterium, which currently contains 14 species including the old species A. radiobacter, A. tumefaciens, A. rubi and A. larrymoorei. Most of these species are able to produce tumours in different plants, nevertheless the genus Agrobacterium also encompasses non-pathogenic species, one species able to nodulate legumes and one human pathogenic species. Taking into account that the species affiliations to five Agrobacterium genomospecies have not been determined yet, an increase in the number of species within this genus is expected in the near future.     

绒鼠属(Eothenomys Miller,1896)系统学研究概况

绒鼠属于1896年建立?针对该属有几个亚属、多少个有效种的问题100多年来一直争论不休,一般认为该属有3个亚属：Eothenomp亚属、Anteliomys亚属,和Caryomys亚属。部分人认为只有前两个亚属;少数人认为没有亚属分化。至于该属的种类争论更大,命名的种类多达20个,但没有一人同时承认20个种,比较多数人认为有11个种。我们通过研究该属部分种的阴茎形态学认为：该属有3个亚属,即Eothenomys亚属、Anteliomys亚属、和Caryomys亚属。

山茶属植物的染色体数目和核型

本文对已报道的(包括作者的研究)山茶属植物的染色体数目和核型作一简单的讨论,结合地理分布情况,提出由二倍体向多倍体进化可能是山茶属植物进化的一个重要途径。山茶属植物的核型多为Stebbins核型分类的“2A”型,表明山茶属植物是一个较原始的种系。本文中12种的染色体数目和2种的核型为首次报道。     

A Study on the Chinese Ormosia Jacks. (Cont.)

The first classification for the genus Ormosia was proposed by Bentham. It was followed by Taubert (1892) in Engler and Prantl’s Nat. Pflanzenf., who divided the genus into 2 sections. On the basis of the pod structure and seed characters Prain (1900) arranged the genus in 2 sections with 4 subsections. In the monograph on the genus Merrill and L. Chen ( 1943 ) limited their taxonomic study to Chinese and Indo-Chinese species, and recognized 34 species and 15 series. Recently Yakovlev (1971-1976) has treated the genus in 6 separate genera. In the present paper the author recognizes 35 species, of which 7 species and 2 varieties are new. The Chinese species of the genus are grouped into 3 sections and 6 series inmy classification.
