Nitella stuartii A.Br. (Characeae), a heteroclemous taxon collected from Santiniketan, West Bengal, India, was found to have a chromosome count of n = 18 in both vegetative and antheridial filament cells which differed from a previous count of« = 15. Using a pre-treatment schedule, karyotype analysis revealed that the present material consisted of four chromosomes with subterminal, nine with sub-median, and five with median constrictions.
