Some New Taxa of Chara from Guangxi and Gansu,China

In order to get a thorough understanding of the Characeae, the specimens collected from Guangxi and Gansu were identified. The result shows that the two provinces, especially Guangxi, are abundant in this family. In this paper, however, reported are only new species, new varieties and new records of Chara in China. They are Chara vernicosa sp. nov. C. globularis var. inflata var. nov. and C. howe-ana var. subgymnophylla var. nov., C. brionica stapf and C. calveraensis comb. nov.

Restoration of Botshol (The Netherlands) by reduction of external nutrient load: Recovery of the Characean community

The formerly rich characean community in Botshol with six species of which the rareNitellopsis obtusa andChara hispida dominated at many sites, decreased to only two species,Chara globularis andC. connivens, in the period 1980–1988. The macrophyteNajas marina also remained at some sites, and the aquatic mossFontinalis antipyretica and the filamentous algaVaucheria dichotoma predominated at many sites. These phenomena may have been due to eutrophication by the inlet of polluted water. This process of eutrophication was stopped by restoration measures in 1989, resulting in a lower phosphorus concentration (ca. 0.024 mg l^–1) and a higher water transparency. Immediately after these measures the Characeae community increased strongly in abundance and number of species. During the summer of 1990, and especially of 1991, a spectacular growth occurred ofChara connivens. Chara connivens was often accompanied byChara hispida. Other species with scattered occurrence wereChara aculeolata, C. aspera, C. contraria andC. Globularis. The reasons for the shift in dominance fromNitellopsis obtusa toChara connivens are discussed. One of the reasons may be the recent higher chloride content which is one of the consequences of the restoration measures.     

Some New Taxa and New Records of Charophyta from Guizhou

Guizhou is situated in the southwestern China and is very rich in algae However, our present knowledge of the Charophytes is scanty. Over 400 specimens were collected from 22 counties or cities and from them 41 species, 2 subspecies, 3 varieties were found. In addition to previously known species of this region, Nitella rasilis, N. paludosa, N. pseudopapillata and N. guizhouensis are new species, N. mirabilis var. libera is new variety, and N. penicillata, Chara burmanica, C. vulgaris var. gymnophylla are new records for China. In this paper, only the new taxa are reported.     

Restoration of Botshol (The Netherlands) by reduction of external nutrient load: recovery of a characean community,dominated by Chara connivens

Till about 1965 a rich characean community occurred in the shallow peat lake Botshol with six species of which the rare Nitellopsis obtusa and Chara major dominated at many sites. In the period 1980–1988 characean biomass strongly decreased and only two species, Chara globularis and C. connivens, remained in small populations at a few localities. Of the macrophyte Najas marina also some small populations remained, while the aquatic moss Fontinalis antipyretica and the filamentous alga Vaucheria dichotoma predominated at many sites. These phenomena may have been due to eutrophication by the input of polluted water. This process of impoverishment was stopped by restoration measures in 1989, resulting in a lower phosphorus concentration (ca 25 µg l^-1) and a higher water transparency. Immediately after these measures the Characeae community increased in abundance and number of species. During the summer of 1990, and especially 1991, a spectacular growth occurred of Chara connivens. C. connivens was often accompanied by C. major. Other species with scattered occurrence were C. aculeolata, C. aspera, C. contraria and C. globularis. The reasons for the shift in dominance from Nitellopsis obtusa to Chara connivens are discussed. From growth experiments evidence was obtained that neither the recent higher chloride level, nor the lowered phosphate concentration were the main factors for the domination of Chara connivens.

Cypripedium wumengense and Its Allies

In addition to describing a new species, Cypripedium wumengense, as well as a new variety, C. bardolphianum var. zhongdianense, nomenclatural and taxonomic notes are made on its allies and the division to which they belong. They are ltrge]y found in the Hengduan Mountains in southwestern China, characterized by the absence of bract, havirg lip more or less covered with small wart-like outgrowths, and that as the capsule matures the scape becomes much elongated. Six species of this group have hitherto been reported, of which, however, C. ebracteatum and C. nutans are regarded here as conspecific with C. fargesii and C. bardolphianum respectively. Thus, including the new taxa described here, it composes five species and one variety: C. bardolphianum W. W. Sm. et Farrer (var. bardolphianum and var. zhongdianense S. C. Chen), C. micranthum Franch., C. fargesii Franch., C. margaritaceum Franch. and C. wumengense S. C. Chen. They are all grouped here into the same section, Sect. Trigonopedium (Franch.) Pfitz., the oldest legitimate name of this group in the rank of section.
