Rhizome oblique, short or nearly creeping. Stipes few, tufted, slender, 



fuscous, ± 7i — 1 c.M. long, puhescent like the rachis and clothed with thin, 



setulose, reddish-brown, spreading scales. Fronds lanceolate, + 6 c.M. long, 



5 7 m.M. broad, pinnate below the much prolonged, pinnatifid apex, the lobes 



3 erecto-patent. Pinnae in + 5 — 6 pairs, erecto-patent, subremote, ^'/j — 5 m.M. 



l^ long, the higher equilateral at the base, entire, oblong, the central inequila-

> lobate. Texture flaccido-herbaceous ; rachis winged ; surfaces piiberulous ; colour

Rhizome creeping, flexuose, the scales brown, lanceolate, acuminate, small. 

 Stipes seriate, slender, + 2 — 6 c.M. long, deciduously scaly like the rachis, 

 the scales minute, crisped, setiform Fronds linear-lanceolate, + 7 '/i — 12^/2 c.M. 

 long, + 1—2 c.M. broad, with + 5 — 6 pairs of pinnae below the terminal 

 one. Terminal pinna long, deeply pinnatifid at the base, narrowed gradually 

 towards the toothed or serrate, acuminate point; lateral pinnae erecto-patent, 

 the highest longest, lanceolate-ohlong, bluntish, sessile; lowest pinnae smallest, 

 nearly stalked, remote, oblong, + 5 — 6 m.M. long, + 5 m.M. broad, blunt, the 

 edge + repan do-denticulate, the base obliquely cuneate, slightly auricled on the 

 upper side. Texture papyraceous; rachis narrowly winged above; surfaces 

 sparingly covered with few, minute, inconspicuous scales on the costae; main 

 veins • oblique, simple, the lower forked. Sori few, minute, the lower anterior 

 of the pinnae often elongate-hippocrepiform, but without/sinus between the 

 branches. — The scales of the rhizome being finely cancellate and the cells 

 coloured this plant is decidedly no Asplenium. (*) —.Forbes' plant (no. 2894), 

 determined by Raciborski as Asplenium pusillum, BL is a young form of 

 Diplazium granuuitoides, Pr.
