Mitotic chromosome counts are reported for 12 species of Oedogonium with the following distribution: two species with 13 chromosomes, two species with 16 chromosomes, five species with 17 chromosomes one species with 19 chromosomes, one species with 32 chromosomes, and one species with 38 + 1 chromosomes. Diploid strains of two species are illustrated and discussed. Cytological comparison of species establishes that there is great diversity in Oedogonium with relation to chromosome number, size, and morphology. 相似文献

Scale-bearing Chrysophytes from nine freshwater bodies in the surroundings of Nijmegen, The Netherlands, have been studied using both scanning and transmission electron microscope.A comparison has been made with a previous study in the northern part of The Netherlands by Wujek & van der Veer (1976).This paper deals with three species of Mallomonopsis, twenty-one species and one variety of Mallomonas, four species and three formae of Synura, one species of Chrysosphaerella, two species of Spiniferomonas and three species and one form of Paraphysomonas. One species of Mallomonopsis, twelve species of Mallomonas, one form of Synura, Chrysosphaerella brevispina and one species and one form of Paraphysomonas are for the first time recorded from The Netherlands. One species of Mallomonopsis and one species of Spiniferomonas could not be identified.Some physical and chemical data of the sampling localities are given. 相似文献

The genus Solms-Laubachia of Cruciferae was established by Muschler in 1912 on
the basis of the Chinese species Solms-Laubachia pulcherrima of Yunnan Province.
Since then, nine species, two varieties and two forms have been recorded. They are
almost all endemic in China except one species—Solms-Laubachia retropilosa Botsch.
which was discovered in Sikkim.
We described in this paper thirteen species, three varieties and one form, of which,
we suppose, three species, one variety and one combination have never been reported
before. Most species grow in the mountainous regions of Szechuan, Yunnan, Tibet,Ching-hai and Sinkiang in China. 相似文献
