attenuate from the very narrow base (about 0.5 mm. 
broad), rigid, the cells with moderately thick, dark 
reddish brown, sclerotic partition walls and transparent 
outer walls, the lumina large; stipe 2 to 7 cm. long, 
glossy purplish brown nearly or quite throughout, 
rounded beneath, the upper face flat to sulcate; lamina 
narrowly triangular, 3 to 8 em. long, 1.5-2.8 em. broad, 
pinnate in the basal part, subpinnate above; rachis 
usually greenish, flat, and distinctly but narrowly 
winged (suleate anteriorly near the base), or in the 
largest plants more slender, glossy brown, and only 
faintly greenish-marginate toward the base, both stipe 
and rachis bearing a few tortuous fibril-like scales; 
basal pinnae distant, opposite, sessile, triangular, nearly 
equilateral, subcordate at the base, obtuse or acutish, 
shallowly crenate-dentate or, in the larger fronds, pin- 
natifid at the base, the resulting pair of rounded lobes 
adnate or subsessile; succeeding pinnae or segments 
gradually smaller, narrower, simpler, and more broadly 
connected, finally contiguous or even imbricate, passing 
evenly into the lobate, long-acuminate apex; leaf-tissue 
rigidly herbaceous or subcoriaceous, the under surface 
bearing numerous few-celled clavate glandular hairs, 
these passing gradually into the gland-tipped capillary 
scales of the vascular parts; sori abundant, dark brown, 
confluent, variable in form and position, the indusia 
firm, white.
