9a Chara aspera Deth. ex Willd. var. aspera

Although similar in its three-rowed cortex structure, it is dioecious, and is a more delicate plant than C. globularis, with well developed spreading spines and stipulodes. A distinctive feature is the occurrence of globular, whitish bulbils on the lower nodes, which it seems largely to rely on for reproduction, rarely being found in fruit. If found and suspected in the field, one needs to make sure that the lower segments of the plant are collected, to avoid overlooking the bulbils. Only one old record for the county.
