 the other ones alternate, sessile, oblong-lanceolate. Pinnulae multijugate, oblong- 

 lanceolate, the lower ones pinnate. Tertiary divisions 6 — 7 m.M. long, 

 3 — 0% m.M. broad, adnate, contiguous, entire, with the central ribs pin-

 subdeltoid, stalked, + produced on the lower side. Pinnulae lanceolate, lower 

 ones stalked, higher ones decurrent at the base. Ultimate lobes ligulate-oblong, 

 the largest ones to 8 m.M. long, 572 — ^ ni.M. broad. Texture herbaceous or 

 moderately firm ; rachises scaly, the scales becoming shorter towards the apices 

 of the fronds and segments, broad at the base and suddenly narrowed into 

 a long, bristle-like, firm, spreading, dark-brown or blackish point; surfaces 

 naked; veins pinnate in the lobes. Sori medial or subcostal, 3 — 5 on each
