96 POLYPODIUM, § DRYN'ARIA. 



scarcely any, fronds l|-2-3 feet and more long 10-15 inches 

 broad firm-coriaceous glossy beneath dimorjDhous ; sterile 

 ones deeply pinnatifid to the very extremity, segments 5-9-10 

 inches long H-2 inches broad oblong sharply acuminate en- 

 tire, terminal one rather large ovate, basal ones suddenly 

 contracted into a lobed wing decurrent on the stipes, vena- 

 tion as in P. Meyenianum ; fertile fronds the same as the sterile 

 but pinnated above with narrow contracted linear subsinuate 

 costules forming a series of large subquadrate primary areoles 

 each of which is soriferous, the sori large orbicular or sub- 

 quadrate and filling up the entire areole. — Dryostachyum 

 splendens, /. Sm. in Hook. Journ. Bot. iii. p. 399, and iv. 

 p. 64, Hook. Gen. Fil. t. 95. — Var. /S, pilosuin ; smaller upper 

 portion of the frond subpubescent. Dryostachyum pilosum,

Hab. Luzon, o, n 90, and 0, n. 89, Cuming. — This again, as indeed Mr. J. 

 Smith has himself intimated, is quite a Drynaria, with the upper portion of the 

 fertile frond contracted into narrow segments, primary veins forming large areoles 

 and bearing equally large sori, some of which are orbicular, others almost exactly 

 square, and the latter the largest, sometimes measuring a quarter of an inch across. 



395. P. (Drynaria) quercifolium, L. ; caudex creeping short 

 stout densely clothed with red-brown satiny lanceolato-subu- 

 late soft scales, fronds coriaceous or subcoriaceous of two 

 kinds; sterile ones varying in size from 3—12 inches and 

 more long and 7-8 inches wide generally dark-brown glossy 

 cordato-ovate variously lobato-pinnatifid often halfway down 

 to the costa; fertile ones 2-3 feet long long-petiolate broad- 

 ovate deeply nearly to the rachis pinnatifid, segments 5-9 

 inches long 1-1 ^ inch wide oblong acuminate entire, vena- 

 tion manifest, costules distinct rather distant united by trans- 

 verse veins forming 4-6 primary soriferous areoles filled up 

 with a network of small quadrangular areoles with or without 

 free veins, sori compital small numerous two in each primary 

 areole consequently in two series between and parallel with 

 the costules. — Linn. Sp. PI. p. 1547. Sw. Syn. Fil. p. 32.
