POLYPODIUM, § PHYMATODES. 7-^ 



quadrate primary areoles which are filled up with a less irre- 

 gular network of which the areoles enclose frequent free and 

 branched veinlets, sori also verj^ irregular as to size and ar- 

 rangement compital, sometimes between the costules is only 

 one large orbicular sorus collectively arranged in a single 

 series parallel with and near to the costa sometimes there 

 are two or three between the costules at other times there is 

 a single or a double series of few sori between the costules 

 and these extremely irregular in shape often oblong and linear 

 (grammitoid) and placed transversely with regard to the 

 costa. — Tliunb. in Linn. Trans. \\. p. 341. Kze. in Bot. Zeit.

355. P. (Phymatodes) hemionitideum,V^^?\\.; caudex creep- 

 ing apparently underground scarcely paleaceous, stipites more 

 or less remote 2 inches to a span and more long winged up- 

 w^ards reddish-brown, fronds 8 inches to 1^ foot long 2-3 

 inches wide membranaceous subchartaceous suljtranslucent 

 oblong or broad-lanceolate acuminate, below rather suddenly 

 very long attenuate and gradually decurrent sometimes al- 

 most to the base of the stipes, entire glabrous, venation very 

 evident and prominent, costules slender horizontal or nearly 

 so united by transverse veins so as to form about five series 

 of large subquadrate areoles and these including small ones 

 with or without free veinlets, sori compital rather large 

 forming one series between the costules and these very irre- 

 gular in shape and size rarely subglobose usually oblong 

 or even (by confluence) linear lying transversely with regard 

 to the costa parallel with the costules. — Wall. Cat. p. 284.
