 iv. 87. Rhizome an erect caudex, exceeding 1ft. high, diameter about 2in., 

 bearing the black base of old stipites mixed -with black scales. Fronds 1 to 2ft. 

 long, simply pinnate, stipes and rhachis more or less covered with black hair-like 



•scales particularly dense at the base. Pinnae petiolulate, 2 to 4in. long, linear- 

 lanceolate, serrulate or the ends sharply serrate, base obliquely truncate, terminal 

 (pinnse 5 to 6in. long, sometimes deeply lobed at the base. Veins once-forked, 

 simple at the apex, terminating at the margin, the upper veinlet of each fork 

 except those near the apex soriferous. Sori narrow, occupying nearly the length

 Benth. Fl. Austr. vii. 750. Rhizome slender, creeping. Fronds pinnate, 1 to 

 l^ft. long. Larger pinnae 3 to 4in. long, deeply pinnatifid, the lower segments 

 jreaching the shortly scaly-hirsute rhachis. Sori usually rather shorter than in 

 A,,sylvaticum. — Bail. Litho. Ferns Ql. 117.

19. A. Sylvaticum (growing amongst trees), Fred ; Hook. Spec. Filic. iii. 

 248, Syn. Filic. 232 ; Benth. Fl. Austr. vii. 750. Rhizome short thick and scaly. 

 Fronds pinnate, from 1 to above 2ft. long. Pinnae membranous, mostly attached 

 by the midrib only or shortly petiolate, the larger ones 6in. long, f to lin. broad, 

 regularly pinnatifid with short rounded denticulate lobes, with a central vein to 

 •each lobe and several oblique parallel veinlets proceeding from it, bearing linear 

 sori extending from the midrib almost to the margin ; indusia of the section, 

 single or double ; upper pinn* gradually smaller and more entire, the uppermost 

 semi-decurrent or confluent. — Bedd. Ferns S. Ind. t. 161 ; Bail. Litho. Ferns 

 <J1. 118. 



Hab : Most of the northern ecrubs.

'20. A. maxunum (very large), Don ; Hook, and Bak. Syn. Filic. 239 ; 

 Benth. Fl. Awtr. vii. 751. Trunk erect, from a few in. to 2Jft. high. Fronds 

 bipinnate, several ft. long and 2 to 3ft. broad, the larger pinnae closely resembling 

 the entire fronds of ..4. sylvaticum. Secondary pinnae lanceolate, acuminate, 3 to 

 €in. lonp, f to lin. broad, pinnatifid with short broad denticulate lobes, but the 

 larger ones more deeply so than in A. sylvaticum and the smaller lobes naore 

 ■oblique and acutely toothed, the pinnae ending in a long lanceolate serrated point, 

 the rhachis glabrous or slightly scaly. Sori narrow-linear and indusia entirely 

 those of A. sylvatica. — Bail. Litho. Ferns Ql. 119.

 257, Syn. Filic. 238 ; Benth. Fl. Austr. vii. 751. Trunk erect, attaining sopoe- 

 times 3 or 4ft. Fronds bipinnate, several feet long, 1 to 2ft. broad at the stipes 

 and rhachis without scales. Secondary pinnae mostly 3 to 4in. long, lanceolate, 

 shortly petiolate, acuminate, more or less deeply pinnatifid towards the base, the 

 lower lobes lanceolate, falcate, minutely serrulate, the upper ones gradually 

 shorter. Sori on the pinnate veins of the lobes as in the preceding species, but 

 much shorter, rather oblong than linear. Indusia of the section opening on one 

 or both sides of the vein.— F. v. M. Fragm. v. 132 ; Bail. Litho. Ferns Ql. 120 ;
