rather thick and fragile, under these larger scales the rachis is densely rufous- and 
adpressedly tomentose partly with articulated hairs, partly with small, reddish scales. 
Secondary rachises similarly scaly and tomentose, while the costule and midyeins 
beneath are rather densely clothed with reddish, small scales, without large, castaneous 
ones and without hairs. Pinne 40—60 cm long; pinnul distant, not touching each 
other, oblong-acuminate, up to 10 cm long, 2—3 cm broad, sessile or nearly so, 
the uppermost ones adnate and shortly decurrent, incised nearly or quite to the 
costula. Tertiary segments or pinnulz, adnate and delated equally to both sides of 
the base, obtuse or shortly acute, 2—2'/2 cm long, 5—8 mm wide, the sinus be- 
tween them triangular, acute, upwards with a broad open space about as broad as 
the segments; margins. regularly and shallowly lobed or serrulate. Veins simple or 
forked with the thickened apex terminating within the margin; the midrib of 
a posterior adnate segment of an upper pinnula 
springs out from the costa 2—3 mm from the costula. 
Costule above antrorsely strigose and the margins 
shortly ciliate, both surfaces otherwise perfectly with- 
out hairs. Sori rather large, a little inframedial, 
exindusiate, -

Evidently a very large species and one of the 
most distinct of the whole group, well marked by 
its two kinds of scales, its distant pinnule, the 
dilated base of the tertiary segments and the 
absence of hairs of any kind of the underside.
