Karyological studies on some Indian Charophyta

Cytological investigations on two taxa of Chara Linn. (C. vulgaris var. gymnophylla f. grovesii and C. zeylanica var. sejuncta f. formosa) and a taxon of Nitella Ag. Leonh. (N. heterodactyla) were carried out. Nuclear events conformed to the standard pattern of mitosis described. The chromosome numb...

Zusammenfassung:	Cytological investigations on two taxa of Chara Linn. (C. vulgaris var. gymnophylla f. grovesii and C. zeylanica var. sejuncta f. formosa) and a taxon of Nitella Ag. Leonh. (N. heterodactyla) were carried out. Nuclear events conformed to the standard pattern of mitosis described. The chromosome numbers determined are n=35 for C. vulgaris var. gymnophylla f. grovesii, n=42 for C. zeylanica var. sejuncta f. formosa and n=18 for N. heterodactyla. All the three taxa were investigated for the first time and are new reports.
