The Genus Tolypella (Div. Charophyta) from Indian Subcontinent-A Cytotaxonomic Approach

抄録

Cytotaxonomic studies in the genus Tolypella (T. nidjca var. glomerata (Desv. in Lois.) Leonh. em. R. D. W.) have been conducted for the first time from Indian subcontinent and a chromosome count of n=11 has been established in this taxon. The hybridized origin of 11chromosome number and the concept of three basic chromosome numbers for this genus as suggested by Sawa (1974) have been upheld. The phylogenetic status of Tolypella has also been discussed in detail.
