Two new taxa of Spirogyra

Summary A new species and a new variety ofSpirogyra have been recorded.Spirogyra varshaii spec. nov. has been described and compared to two related species ofSpirogyra. This species has a very distinct subdenticulate to denticulate type of ornamentation of the zygospore wall and differs from the other two related speciesS. chakiense andS. verruculosa in having different dimensions of the zygospores and in the number of chloroplasts. A new variety,Spirogyra chakiense var.lucknowense var. nov. has been described. It differs from the speciesS. chakiense in possessing some differences in the dimensions of the cells and the zygospores from the type species.

Zusammenfassung Eine neue Spezies und eine neue ArtSpirogyra sind eingetragen worden.Spirogyra varshaii Spec. nov. ist beschrieben worden und mit zwei verwandten Spezies verglichen. Diese Spezies hat einen sehr deutlichen unterzahnigen bis zum zahnigen Typus der gestickten Zygosporeswand, und sie unterscheidet sich von den anderen zwei verwandten SpeziesS. chakiense undS. verruculosa daß sie verschiedene Ausdehnungen der Zygosporen und auch eine verschiedene Zahl der Kromatophoren hat. Eine neue ArtSpirogyra chakiense var.lucknowense var. nov. ist auch beschrieben worden. Sie unterscheidet sich von der SpeziesS. chakiense weil sie einigen Unterschieden in Ausdehnungen der Zellen und auch der Zygosporen hat im Vergleich mit der Typusspezies.

     

A revised classification of the higher taxa of the Ostracoda (Crustacea)

Focusing on palaeontological data from the literature of the last four decades, a new classification of the Ostracoda is outlined. The superorder Podocopomorpha is accepted as a mantle term for the ‘P-orders’ Palaeocopida, Punciocopida, Platycopida and Podocopida; its counterpart are the Myodocopomorpha (Cypridinida, Halocypridida and ? Leperditicopida). The Podocopida comprise the suborders Bairdiocopina, Cytherocopina, Sigilliocopina, Cypridocopina, Darwinulocopina and Healdiocopina (n.;=Metacopina s.s.). The non-calcifying ostracodomorph arthropods (Archaeocopida and Phosphatocopida) of the Early Palaeozoic, now excluded from the Ostracoda by many authors, are also considered briefly.     

Some new taxa ofPotentilla L.

Five new species and two varieties from the sectionMultifidae are described from the Sino-Himalayan region. They are referred to the affinity ofP. multifida L. andP. griffithii Hook. f.; one of the new species is probably related toP. gerardiana Lindl. and one is intermediate between the species of the sectionsMultifidae andNiveae.     

Miscellaneous new taxa of Bromeliaceae (XVI)

Four new taxa of Bromeliaceae are described:Billbergia acreana from Brazil;Pitcairnia chocoensis from Colombia; andGuzmania diazii andPitcairnia filifera from Peru. Also included is the new nameWerauhia moralesii from Costa Rica. Miscellaneous new taxa of Bromeliaceae (XV) appeared in Selbyana 21: 125–131. 2000.     

东亚砂藓组织培养技术方法研究

以东亚砂藓（Racomitrium japonicum）配子体为外植体,比较了不同消毒液对消毒效果的影响,对接种消毒外植体的培养基进行了尝试性筛选,并研究了蔗糖浓度对东亚砂藓配子体生长的影响。结果显示,将东亚砂藓配子体用2％洗洁精溶液浸泡数分钟后,再用0．02％的升汞处理45-60S的消毒效果最佳;有机培养基是无菌外植体接种的最佳培养基;3％的蔗糖更有利于无菌外植体产生的原丝体团和幼嫩配子体的生长。     

柔膜菌科新分类群及中国新记录种（英文）

对来自我国不同地区的柔膜菌科真菌进行了分类研究,发现3个新种(新疆绿胶杯菌、多隔拟散胞盘菌、河南新胶鼓菌)和1个新变种(落叶松芽孢盘菌小囊变种)以及3个未命名种,分别属于绿散胞盘菌属(Chlorencoelia sp.8357)、斯特罗盘菌属(Strossmayeria sp.1683)和丝绒盘菌属(Velutarina sp.4115),报道2个中国新记录种(卷边盘菌、泪滴暗被盘菌)。对上述分类群进行了详细的形态解剖学描述和图解,对新分类群与相近种的区别进行了讨论。
