中国果疣衣属地衣的研究

果疣衣属地衣系子囊菌门Ascomycota,子囊菌纲Ascomycetes,茶渍衣亚纲Lecanoromycetidae,鸡皮衣目Pertusariales,鸡皮衣科Pertusariaceae的成员。由于粉色果疣衣Varicellariarhodocarpa在中国的首次发现,使中国地衣区系中新增添了一个属:果疣衣属Varicellaria。该属迄今已知仅含三种,即粉芽果疣衣V.kemensis,八孢果疣衣V.carneonivea及粉色果疣衣V.rhodocarpa。果疣衣属为壳状地衣,地衣体微薄,膜质;子囊盘茶渍型,单个或数个聚生于瘤状果疣中;类侧丝多分枝并呈网状缠绕;子囊内含单孢或八孢;子囊孢子大型(长度为200~400mm),双胞,无色透明,椭圆形;孢子壁厚达27mm;与鸡皮衣属不同之处在于前者子囊内含双胞孢子,后者子囊内含单胞孢子。由于该属在中国是首次被发现,为了进一步的研究,文中还提供了该属迄今已知的全部三种的分种检索表。粉色果疣衣以其地衣体基本无粉芽和遇Pd呈负反应而区别于粉芽果疣衣,以子囊内含单孢而区别于八孢果疣衣。通过薄板层析法首次从该种髓部检测出茶渍衣酸。其地理成分为北极高山种,主要分布于欧洲的挪威、瑞典、芬兰、阿尔卑斯山脉,喀尔巴阡山脉、苏格兰以及北美洲;在亚洲迄今只见于日本与中国。

The Chromodorididae (Opisthobranchia: Mollusca) of the Indo-West Pacific: the genus Glossodoris Ehrenbergh (= Casella, H. & A. Adams)

The genus Glossodoris Ehrenberg is reviewed and 28 species are placed in the genus. Seventeen species are fully described and of these, seven are named as new species. Four others are considered new to science, but insufficient material is available to name them. Published information on a further 11 species is included as is a discussion on phylogenetic trends within the genus.     

Description of a new cestode species Mircia shigini gen. et sp. n. (Cyclophyliidea: Schistotaeniidae)

A new genus and species of cestodes from the great-crested grebe Podiceps cristatus collected in the Eastern Europe is described. The genus Mircia gen. n. in addition to the type species M. shigini gen. n. includes the following species formerly being included in the genus Joyeuxilepis Spassky, 1947: M. decacantha (Fuhrmann, 1913) comb. n., M. decacanthoides (Borgarenko et Gulyaev, 1991) comb. n., M. fimbriata (Borgarenko, Spasskaja et Spassky, 1972), comb. n., and M. uralensis (Gulyaev, 1989) comb. n. Brief revision of the genus Joyeuxilepis is provide.     

A Study on the Genus Cephalotaxus Sieb. et Zucc.

The genus Cephalotaxus contains a small number of species. It is adequately appreciated as a newly discovered cancerresistant medicament for the alkaloids obtained from its branches leaves and barks are of curative effect. This paper deals with the classificatory revision based on the morphological features, with the reference to the anatomical characters of leaves, types of alkaloids and pollen morphology observed. Two new combinations are proposed, and 4 species and varieties are reduced in the paper. The genus Cephalotaxus is thus suggested to consist of 2 sections and 9 species. The trees occur in East Asia and the north of Indo-China, with 88% found in China where is the distribution centre and refuge of the genus. The genus in discussion is of unique morphological features which are distinctly different from these of Amentotaxus, Cephalotaxaceae, containing a single genus of Cephalotaxus, is closely related to Taxaceae, and therefore the Cephalotaxaceae is best placed in the Taxinieae of Coniferales.     

Karyotype Analysis of Cycas panzhihuaensis L. Zhou et S. Y. Yang

This paper reports chromosome number and karyotype analysis of Cycas panzhihuaensis endemic to China. The material was collected from Dukou, Sichuan. It is a diploid species, with 2n=22=2m+4sm+4st+l2t. The karyotype of Cycas panzhihuaensis is different from that of the other species of the genus Cycas, which was known to be 2n=4m+8st+10t. The former is a new karyotype in the genus. The authors briefly discuss karyotype evolution of the genus Cycas in this papar.     

Korotnevella hemistylolepis n. sp. and Korotnevella monacantholepis n. sp. (Paramoebidae), two new scale-covered mesohaline amoebae

Two new species of Korotnevella Goodkov, 1988, Korotnevella hemistylolepis n. sp. and Korotnevella monacantholepis n. sp., are described from mesohaline ecosystems. The amoebae are characterized on the basis of light and electron microscopy with special emphasis on the structure of the basket scales, which have species-specific architecture. The two new species are the second and third ones recovered from environments other than freshwater. In terms of scale morphology they most closely resemble a freshwater species, Korotnevella bulla (Schaeffer, 1926) Goodkov, 1988. Two genus names, Dactylamoeba Korotnev, 1880 and Korotnevella Goodkov, 1988, are in current use. The latter name is preferred, pending rediscovery and characterization of Dactylamoeba elongata Korotnev, 1880, the type species of the genus. Korotnevella species can be divided into three groups on the basis of scale morphology, suggesting that the genus may not be monophyletic. A key to species is provided.     

宽带蕨属（水龙骨科）的系统学研究

对喜马拉雅和横断山地区特有的水龙骨科的宽带蕨属Platygyria Ching&S.K.Wu植物进行了形态学、分类学、生态和植物地理学的观察与分析,探讨了该属植物的系统位置、亲缘关系和生态适应性,推测宽带蕨属是随着喜马拉雅山脉的隆升,由瓦韦属Lepisorus（J.Sm.）Ching网眼瓦韦群植物适应高寒生态环境演化而来的新生类群。确定宽带蕨属有5种,即川西宽带蕨P.soulieana（Christ）X.C.Zhang&Q.R.Liu、多变宽带蕨P.variabilis Ching&S.K.Wu、耳基宽带     

Phylogeny and biogeography of the genus Pseudectinosoma, and description of P. janineae sp. n. (Crustacea, Copepoda, Ectinosomatidae)

Recent stygobiological investigations carried out in the circum-Mediterranean area resulted in the discovery of a new species of the genus Pseudectinosoma Kunz, described herein as P. janineae sp. n. The taxonomic status of the genus is reviewed in a phylogenetic perspective. The origin of the present-day distribution of the genus Pseudectinosoma is reconstructed both from patterns of relationships among the species and from palaeogeographical data.     

Proposal to change the genus designation Serpula to Serpulina gen. nov. containing the species Serpulina hyodysenteriae comb. nov. and Serpulina innocens comb. nov.

The bacterial genus Serpula Stanton et al. 1991 is illegitimate due to the existence of a fungal genus Serpula Pers. ex S. F. Gray. Consequently, a new genus designation, Serpulina, is proposed for this spirochete genus. Serpula hyodysenteriae, the type species, and Serpula innocens Stanton et al. 1991, therefore, become Serpulina hyodysenteriae comb. nov. and Serpulina innocens comb. nov.

The Chromodorididae (Opisthobranchia: Mollusca) of the Indo-West Pacific: the genus Ceratosoma J. E. Gray

The genus Ceratosoma (Nudibranchia: Chromodorididae) is reviewed and seven species, including two new species, are recognized. Species of the genus are known only from the Indo-West Pacific and it is suggested that the external body shape is the most useful character in distinguishing species.     

中国复叶耳蕨属的分类研究

1828年荷兰植物学家Blume在他的《瓜哇植物简志》(Enum.P1.Jav.)中,根据Arachniodes aspidiodes Blume这个种,建立了复叶耳蕨属Arachnicdes,但一直未被各国植物学家所承认。我国蕨类植物专家秦仁昌教授1934年对本群蕨类植物的生活习性、外部形态和分枝图式等,进行了深入细致的研究,证明了它是一个自然类群,并指出了在系统分类上介于耳蕨属Polystichum Roth和鳞毛旅属Dryopteris Adans之间,当时他把本群植物(包括毛枝旅属Leptorumchra H. Ito和假复叶耳蔗属Acrorumo-hra H.Ito的一些种)归入了分布在大洋洲和非洲的Rumchra Raddi属中。

Paraphysomonas faveolata sp. nov. (Chrysophyceae), a fourth marine species with meshwork body-scales

Paraphysomonas faveolata sp. nov., the eighth described species of this genus of colourless chrysophycean flagellates, has heterokont flagellation, parabasal nucleus and silicified body-scales. It is the fourth known species with meshwork scales, these being of two types: flat “cobweb” scales and scales with a planar “honeycombed” extension arising from a “cobweb” base. The organism is compared with the other species of the genus and the case considered for placing forms with meshwork scales in a new genus, separate from forms with spined scales. This step is not taken and the taxonomic status of the genus is discussed in relation to the Ochromonadaceae and other genera of the Synuraceae.
