Abstract

A new variety, Chara corallina var. kamrupensis P.P.Baruah, S.Bhattacharjee, N.Kalita & B.Boruah var. nov. is described from Kamrup District, Assam (India), based on the observations made under light and scanning electron microscope. This new variety differs from the other two taxonomically accepted varieties of the species viz., C. corallina var. kyusyensis K.Imahori and C. corallina var. portonovensis D.Subramanian in having bracts throughout the body, number of spirals in oogonia, and reduced size of antheridia & coronula cells.
