 Genera of the Solanum-Cassia Type. Distribution. 



We find that the Indian region has 1 1.8 per cent., the South American 

 28.8 per cent., the Austrahan region 20 3 per cent., and the extra-tropical 

 South American region 6.7 per cent, of the members of this type confined 

 exclusively to their limits. The average for these four regions is 16.9 per 

 cent., while the average for the other ten regions is .9 per cent., six of the 

 regions having no endemic representatives of this type at all. Considering 

 all representatives of the Solanum-Cassia type occurring in the several 

 regions, whether endemic there or not, we find that the Indian region 

 contains representatives of 27.1 percent, of the 59 genera, the tropical 

 South American region 44 per cent., the Australian region 30.5 per cent., 

 and the extra-tropical South American 13.5 per cent. The average for
