The degree of isolation indicated by the endemic percentages is so great that we 

 are justified in considering the district phytogeographically distinct, more particularly 

 since it is found that a union of this district with the only one to which its species 

 are known to be distributed, while increasing the total number of species, would decrease 

 the endemic percentage for the conjoint 

 the artificial species, and from 88*4°/ to 76'4°/ if calculated from probable natural units. 



From the island of Java five forms have been reported. These are G. phlomoidcs, 

 morphologically very distinct, and though extending to the island of Madura not reported 

 from any other part of the Malay archipelago; " G, Jlavescens" (Anthocoma flave
