(Irt) A. nanuiii, Christ, Philipp. Journ., II, 161. 



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

 fuscous, + 7^ — 1 c.M. long, pubescent like the rachis and clothed with thin, 

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

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

 erecto-pateht. Pinnae in ± 5 — 6 pairs, erecto-patent, subremote, 2^2 — S m.M. 

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

 teral, auricled on the upper side, subcrenate, the lowest inequilateral, crenato- 

 lobate. Texture flaccido-herbaceous ; rachis winged ; surfaces puberulous ; colour 

 bright-green; veins forked, hardly pinnate. Sori 5 — 6 to a segment, small, 

 hardly 1 m.M. long, ochraceous; indusium lanceolate, rarely aspidioideo-reniform.

Rhizome creeping, flexilose, 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'/^ — 12 '/a 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-oblong, bluntish, sessile; lowest pinnae smallest, 

 nearly stalked, remote, oblong, ± 5 — 6 m.M. long, ± 3 m.M. broad, blunt, the 

 edge ± repando-denliculate, 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 grammitoides, Pr.
