 more or less winged, segments spreading 6-8 inches long \ an inch or less to 1 j inch wide linear-lanceolate or broad oblongo-lanceolate 

 ♦finely acuminate subopposite and very distant, generally contracted near the base then dilated above, and so extending above and de- 

 current below as to form a narrow or broad wing between the segments, veins sometimes slightly costuliform but usually they constitute 

 rather large unequally-sized hexagonal areoles including free clubbed veinlets, sori linear obliquely patent varying much in length and 

 in breadth, commencing near the costa but never extending to the margin.— Hook. Sp. Fil. v. p. 161;— Grammitis decurrens, Wall Cat n. f
