 | | Nitella C. Agardh (Charales) is characterized by having once or repeatedly forked hranchlets composed of unicellular segments and a one or more-celled terminal segment (called a 'dactyl'), two tiers of coronal cells in the female reproductive organ, and laterally compressed oospores (Wood 1965); around 200 taxa have been described worldwide (Wood 1965). |
 | | In Wood's (1965) worldwide monograph of the Charales, the genus Nitella is divided into three subgenera, Nitella; Hyella R.D. Wood, and laquo; R.D. Wood, based on the differences in the number of cells forming a dactyl and the shapes of the end cells (Wood 1962, 1965). |
