Notes
Note. The robust collections seen only from coastal and subcoastal southern Mozambique (SS and LM) are probably only a very distinct maritime ecoform (prostrate or decumbent plants up to 80 cm. in diameter, base of stems woody, stems branched, leaves from base of stems and branches up to 20 x 6 mm., elliptic-obovate with margins entire or 1-dentate, all parts of plant, including nutlets, densely pubescent-villous); they resemble phenotypically some forms of the S. African Laurembergia repens (L.) Berg., but have the flowers arranged in fascicles composed and disposed as in typical L. tetrandra subsp. brachypoda.
