POLYPODIACEE 
ANTROPHYUM FORMOSANUM Hieronymus, Hedwigia 57: 210 (1915); C. Chr. Ind. 
Fil. Suppl. IT. 4 (1916). 
Antrophyum plantagineum Christ (non Kaulf.), Bull. Herb. Boiss. II. 4:. 610 (1914). 
Rhizome short, erect, densely scaly at the base of stipe; scales lanceolate, 
fusco-brown, thin, iridescent, serrulate with hair-pointed tip; fronds fasciculated, 
sessile, lanceolate, 8-15 cm long, 1.2-1.8 cm broad, acuminate, gradually attenuate 
towards base; tevture herbaceous, glabrous on both sides, no midrib; venation re- 
ticulated, fine but distinct against light; sori linear, following the course of groov- 
ed veins, paraphyses broad, ribbon-like.

From other species of the genus known in the region, our fern can be easily 
distinguished by its very broad and ribbon-like paraphyses in the sori and much 
thinner fronds. Our plate is based upon a specimen from Kwangtung (leg. 
N. K. Chun 41480), which matches the type from Formosa very well.
