 Sori inframedial, somewhot remote from the costulae, on the 1 — 7 lower 

 veins, distinct or finally confluent, subtended by a minute scale on the 

 inner side. 



Forma typica. — Br. India across Malaya to Formosa. 



War. inajoi* : Main rachis fulvo-stramineous, naked or furfuraceous ; 

 pinnulae caudate, cut down to a slender, black costa; lobes oblong, ± 

 2'/2 mm. broad, obtuse, crenulate; costae scaly with roundish, peltate, 

 yellow, umbilicate squamules; veins 2 — .3-furcate. — Mindanao.

Stipes very short because of reduced pinnuae coming down almost 

 to the trunk, almost black, minutely scurfy and bearing harsh, acicular, 

 dark scales, such as extend some 30 cm. up the upper surface of the 

 rachis, densely spiny. Fronds ± 1 '/i m. long, the rachis spiny only near 

 the base, very minutely and sparsely roughened above, brown, bearing a 

 deciduous scurf beneath. Middle pinnae + 35 cm. long, subsessile, abruptly 

 acuminate, the rachis scaly, the scales furfuraceous, more persistent. 

 Pinnulae 7 — 11 cm. long, + 2 cm. broad, sessile, acuminate or cordate, 

 cut at the base to the costa, elsewhere deeply pinnatifld ; segments 

 serrulate and subfalcate at the apex, obtuse, ± 3 mm. broad, the lowest 

 ones free, sessile, not adnate. Texture coriaceous; upper surface naked, 

 very dark, lower paler; costae dark-hairy above, beneath purplish and 

 minutely and deciduously scaly; costulae naked above, scaly beneath; 

 veins up to 13 on a side, mostly forked. Sori costular, small; indusium 

 usually represented by a minute scale.

Stipes + 60 cm. long, spinose, brown-scaly at the base. Fronds 

 ± 180 cm. long, the main rachis spinulose, dark-hairy above, clothed like 

 the secondary rachises with dirty -brown, rather deciduous scales various 

 in shape, the longest of which are hnear-subfihform. Pinnae + 45 cm.
