It is to their advantage to appropriate as much soil as possible to the exclusion of others of their own or ot diflerent kinds. Some species of Bnuisvigia and JLnnantlius spread their flat leaves closely upon the ground, preventing others from gaining a foothold, and smothering any weaker plant which may have taken root in the soil which their leaves can cover. So the plants appropriate water and food material from a wide area. Foreign Immigration.—Have )ou ever thought how much or how little South Africa owes to other countries for its flora?
