small, acuminate scales. Pinnae oblong-lanceolate, + 45 c.M. long, 12— 

 c.M. broad. Pinnulae lanceolate, 1 '/j — 2 c.M. broad, narrowed from the mid 

 to the apex, cut down to the rachis into linear, entire or rarely crenula 

 divisions ± 2'/j m.M. broad, with a distinct space between them. Text 

 firm; subrigid; both surfaces green; rachises and under surface densely cove: 

 with small, ovate-lanceolate, cuspidate scales on the midribs; veins 9 — 10 

 each side, distinct, forked from the base. Sori close to the midribs; indusi 

 fragile, membranaceous, soon breaking down to the base.

Fronds 3-pinnate; rachises all dark-coloured,, opaque, clothed with ru 

 tomentum and muricate with short, black, sharp spines Piimulae 10— 

 c.M. long, 1 — 2 c.M. broad, oblong, pinnate, pinnatifid only near the narrc 

 acuminate point. Tertiary divisions scarcely 7'/j m.M. long, linear fron 

 broad base, acute, subfalcate. Texture coriaceous; under surface cobwebl 

 veins immersed, inconspicuous. Sori near the middle of the pinnulae, occupy 

 the whole space between the midribs of the ultimate divisions and the recur' 

 margin; indusium thin-membranaceous, whitish, breaking down into variou 

 lobed and laciniated segments. The javan plant (Logi Schoffor) has tho ultim
