From these figures it will be seen that the plants of saline habit 
constitute a little over 20 per cent and the invaders something above 
79 per cent of the vegetation as reconstituted. It may be of interest

belongs to four families, while the remainder belongs to many scattered 
families, the figures being as follows:
