According to their distribution, as now known, these ferns may be 
classified as. follows : 
Species common to the Malayan region and to China, Japan or 
Formosa 31 
Malayan species reaching Luzon 77 
Malayan species passing Mindanao but not reaching Luzon 8 
Malayan species not passing Mindanao 23 
Philippine species not confined to Mindanao 14 
Species confined to Mindanao, not to San Ramon 4 
Local species 27 
Total 1 184 
The local species and those confined to Mindanao are valueless in a 
statistical study of the affinities of the flora, and, in the same connection, 
the species confined to the Philippines may best be regarded as endemic 
and left out of account. There are then left 139 species known to occur 
outside this Archipelago. 
Every one of these 139 species is Malayan , 31 of them being known in 
China, Japan or Formosa also. Nearly half of these 31 are known only in
