This tabic shows that tropical America has 62.5 per cent 

 of all the apically dehiscent species of the Solanum-Cassia 

 type, the Indian region 8.9 per cent, the Australian region 

 10.1 per cent, the extratropical American region 5.47 



per cent, while the other ten regions average but 1.52 



per cent. 



Solatium and Cassia comprise 1,382 of the 1,827 species 



of the foregoing tables. Anticipating the suggestion that 



Solarium and Cass 



A 



ncrica may account for the very high percentage of 

 apically dehiscent species found there, I have given in 

 Table E the distribution in numbers and per cents of all the 

 apically dehiscent species except those of these two genera 

 and, for comparison, have figured the per cents of these 

 genera occurring in each region.
