NOVEMBER 15, 1910] Tue Ferns or Movnr Aro 795 
ic list, every species in it has relatives to the south. Of the 
thirty species of Dryopteris, nineteen are Malayan, but not one 
passes Luzon. Of the twenty-six Hu-polypodia, seventeen are 
Malayan; not one passes Luzon, and only five pass Malaya in 
other directions. 
Construing Malaya as extending from the Moluccas to Su- 
matra, one hundred and seventeen of the Apo ferns are known in 
Malaya and pass its boundaries in other directions Of these, seven 
are pantropic, and fifty-two pass Malaya both eastward and west- 
ward. Of the remainder, thirty are known to the east or south east; 
and twenty-eight to the west or north-west. These numbers are 
practically equal. But if I had tried to construe Malaya as exclud- 
ing Celebes, affinity of the flora would have seemed to be over- 
whelmingly with the region to the east. So faras the testimony 
of ferns goes, Wallace’s line has absolutely no reason for being 
imagined. I will add that I have recently had an opportunity to 
study a considerable collection from Papua, near the eastern end 
of New Guinea, and that its fern flora is as unmistakably 
Malayan in character as is that of the Philippines.
