 the Philippines. 



PLAGIOGYRIA ADNATA (Blume) Bedd. Ferns Brit. Ind. (1865) t. 51. 



Kwangtung Province, Loh Fau Mountain (Lofaushan), Merrill llllU. 

 August 12, 1917, in damp shaded ravines, altitude about 1,000 meters. 



The specimens have distinctly 4-angled stipes and conform v^^ell with 

 Malayan and Philippine specimens of this species. From Copeland's de- 

 scription it cannot be the same as Plagiogyria tenuifolia Copel. {Lomaria 

 matthewii Christ) , the only representative of the genus previously reported 

 from Kwangtung Province. 



POLYPODIUM Linnaeus 



POLYPODIUM OLIGOLEPIDUM Baker in Card. Chron. II 14 (1880) 494; 

 Takeda in Notes Bot. Gard. Edinb. 8 (1915) 276, cum descr.! 



Polypodiuvi kawakamii Hayata in Bot. Mag. Tokyo 23 (1909) 77, Ic. 



PI. Formos. 5 (1915) 318, /. ISO. 

 Polypodium arisanense Rosenst. in Hedwigia 56 (1915) 347. 

 Kwangtung Province, Loh Fau Mountain (Lofaushan), Merrill 10221, 

 10684, Levine I486, October, 1916, and August, 1917, on ledges and boulders 

 in damp shaded ravines, altitude 900 to 1,050 meters. 



This form was included by Dunn and Tutcher in Polypodium lineare 

 Thunb., and has been indicated by Christ as a variety of Thunberg's species; 

 it is certainly distinct from Polypodium lineare Thunb. The Kwang:tung 

 specimens agree perfectly with the original description of Ilayata's species, 

 with his additional data and figure, and with Formosan specimens from 

 Arisan, KawakamU, Shimada & Ito 19!, Faurie 472'., the latter a cotype 

 of Polypodium arisanense Rosenst. 



POLYPODIUM HANCOCKII Baker in Journ. Bot. 23 (1885) 106. 



Kwangtung Province, Loh Fau Mountain (Lofaushan), Merrill 10956, 

 August 24, 1917, on forested slopes of damp ravines, altitude about 1,000 

 meters; very rare, but three specimens seen. 



This species has previously been reported only from Formosa, the Kwang- 

 tung specimens agreeing with the description and with Formosan material. 

 I do not agree with Takeda's disposition of the species, who places it as a 

 synonym of Polypodium pteropus Blume. 



PTERIS Linnaeus 



PTERIS FAURIEI Hieron. in Hedwigia 55 (1914) 345. 



Kwangtung Province, Loh Fau Mountain (Lofaushan), Merrill 10158, 

 10664, October, 1916, and August, 1917, on talus slopes in damp ravines, 

 altitude 900 to 1,050 meters; Tong Woo Mountain, Levine X- Groff 50, 

 November 18, 1916. 



This species is one of the numerous ones segregated by Hieronymus from 

 the collective Pteris quadriaurita Retz., and was probably included by Dunn 

 & Tutcher in Pteris biaurita Linn., from which it is very distinct. Hierony- 

 mus based his species on material from Formosa, Oshima, and Amoy.
