4. P. grammitidis, #. Br. Prodr. 147.—Rhizome short, tufted, 
‘crowned with subulate-lanceolate scales; roots long, fibrous. Stipes 
short, wiry, naked, 1-2in. long. Fronds tufted at the top of the 
rhizome, very variable in size and shape, 3-9 in. long, 1-3 in. broad, 
lanceolate to oblong-lanceolate or narrow-ovate, acuminate, some- 
times caudate, dark-green, coriaceous, quite glabrous, pinnatifid 
almost to the rhachis. Pinnez often unequal, linear, decurrent on 
the rhachis at the base and confluent; in large states 1-3 in. long, 
4 in. broad, deeply lobed or pinnatifid; in small forms shorter, 
entire or sinuate or shortly lobed; rarely the pinne are reduced to 
short triangular lobes, so that the frond is narrow-linear in outline. 
Veins obscure, simple or forked. Sori oblong or rounded, usually 
one at the base of each segment of the pinnz, more rarely 2-4 to a 
segment.—A. Cunn. Precur. n. 177; Raoul, Choix, 37; Hook. Sp.
