Rhizome short, stout, creeping, the scales copious, dark-reddish-brown 

 liuear. Stipes of barren fronds S'/j — 10 c.M. long, those of fertile fronds 

 about 50 c.M. long, both clothed below with narrow, spreading scales. Bar- 

 ren fronds to 50 c.M. long or longer, typically 5-fid, sometimes simple and 

 5 — 8 c.M. broad or pinnate, sometimes rooting at the apex, the pinnate fronds 

 to 60 c.M. long. Pinnae acute, entire, lanceolate, rachis winged in the more 

 complex forms and the lowest pinnae forked. Texture papyraceous; surfaces 

 naked; main veins distinct nearly to the edge, with regular transverse vein- 

 lets and copious ai'eolue with included free veinlets. Fertile fronds typically 

 5-fid, the central segment + 15 c.M. long, the lateral ones + 10 c.M. long, 

 both 5 — 4 m.M. broad, exceptionally simple or pinnate. — Exceedingly varia- 

 ble. Copeland includes Ibis under Uemigramma lat>f'iola (Syngramma ZoUin- 

 geri, Diels. ; pi'ubably he is correct in this, and I am inclined to believe that 

 Hemigraiijma (Syngramma §) would better be treated as a distinct genus.
