Very near the type which is known to exist in Celebes and the 

 Philippines. I have not seen either the authentic specimen or original descrip- 

 tion. So far as is concerned a specimen from the Philippines labelled " Poly- 

 podium decrescens CHRIST, teste CHRIST, Bagnen, Lepanto, Luzon, 6500 ft. 

 Nov. 1905, No. 1916," and figures given in the Philip. Journ. Sc. I. Supp. 

 II. t. 17, the present fern is slightly different from the type in having 

 broader fronds and longer stipes. This new variety is somewhat near 

 P. otiiqucdum DRUDE, but quite distinguishable from it in having linear obtuse 

 pinnae arranged in a much acuter angle and by the elevated (not immersed) 

 rounded sori. It is also near Polypodium Thwaitesii BEDD. (Handb. Fern. 

 Brit. Ind. p. 310, fig. 1 64 and Fern. Brit. Ind. t. 188.), 

 P. repandulum 

 METT. (BEDD. 

 Handb. Fern. Brit. 

 Ind. p. 313, fig. 

 167) and P. sub- 

 fa I ca turn BL. 

 (BEDD. Fern. Brit. 

 Ind. tt. 76 et 189), 

 but differs from all 

 of them and especi- 

 ally from the last 

 one by the entire 

 pinnse or lobes of 

 the fronds.
