Charophyte throughout the year either in its natural condition or in cultivation will do well to examine the roots from time to time to ascertain if bulbils are being produced. There are three distinct types of bulbil: (1) con- sisting mainly of a large nearly spherical cell (Fig. 11), (2) more or less amorphous, consisting of an agglo- meration of numerous small cells (Figs. 12 and 13), . (3) star-shaped, being modified branchlet - whorls (Fig. 15). The first type of bulbil, those of spherical form, are found among British species, in Ghara aspera, C~.
