FILICES. 59 



segments contiguous, oblong, attached by a base broader than the 

 rest of the pinnule or segment, scarcely tapering towards the obtuse 

 apex, crenate-serrate or entire, flat or (in small specimens) with the 

 apices slightly incurved. Indusium rather large, regularly convex, 

 with the margins not incurved round the sporangia, glabrous. 

 Spores with a few rather large rounded separate tubercles.

Fronds commonly arching backwards, at least when large. Stipes 

 rather short ; scales rather numerous, diaphanous pale brown, slightly 

 ciliate, the lowest ones broadly lanceolate, the upper ones linear, inter- 

 mixed with numerous flexuous-like ones, almost all falling off early and 

 leaving the rachis naked. Lamina rather flaccid, bright glistening 

 green, with white hyaline scales when it is unfolding, ultimately 

 bright green, a little paler beneath, where it is not glandular even 

 on the rachis, broadly elliptical-oblong or oblanceolate-obiong, pinnate ; 

 lowest pinna? broader than the others and more triangular, and as 

 well as those up to the middle of the frond spreading or even decurved, 

 all of them flat, pinnate ; pinnules not contiguous, strap-shaped or 

 the lower ones triangular-strapshaped, attached by a base which is 

 narrower than the lower part of the pinnule, inciso-serrate, or some 

 of them near the base even pinnatifid, with the serrature sometimes 

 again serrate, tapering towards the subobtuse or subacute apex, fiat. 

 Indusium rather large, regularly convex, with the margins not 

 incurved round the sporangia, glabrous. Spores with a few small 

 rather inconspicuous separate tubercles.
