Stipes slender, very short, slightly scabrous, clothed 
with a few dark, narrow scales towards the base; fronds 
dimorphic, narrow-linear, 30-45 cm. long and 2-5 cm. 
broad, scabrous, subcoriaceous, deeply pinnatifid, the seg- 
ments all adnate to the rhachis by their broad bases or 
occasionally a free longer pair of pinnae produced under 
the very small basal ones; sterile segments rather broad, 
closely confluent ; fertile ones rather distant, much nar- 
rower, the fronds terminating in a narrow, caudate apical 
segment; sori mostly in a confluent line, and eventually 
covering most of the under surface. 
Distribution. — South-eastern Queensland: Blackall 
Range, Marooehie, Eudlo, Yandina, Buderim Mountain, 
Mooloolah Scrub, Candle Mountain.

D. blechnoides A. Cunn. in Hook. Comp. Bot. Mag. II., 
355 (1836); Benth. FI. Austr. VII., 741 (1878). 
Plant with an erect arborescent caudex up to 30 cm. 
high and 2.5 cm. thick ; stipes tufted, scabrous at the base, 
more or less clothed with narrow blackish scales; fronds 
up to about 60 cm. long with the short stipes, and 16 cm. 
broad in the middle, deeply pinnatifid with the segments 
closely confluent and adnate to the rhachis by their dilated 
bases or with a few free pinnae at the base, lanceolate in 
outline, gradually narrowed towards each end, the term- 
inal segment short ; upper segments close, linear-ensiform, 
acuminate, coriaceous, margins spinulose-serrulate ; basal 
ones more distant and gradually shortened ; sori oblong, 
distinct, always in one row on each side of and appressed 
to the midrib. 
Distribution . — Confined to New South Wales : Nepean 
River, Cedar Creek, New England, Warraburra River. 
Apparently very rare. 
4. D. candata R. Br. Prodr. 151 (1810). 
Fronds weak on slender, usually smooth stipes of 
variable length, narrow linear-lanceolate in outline, sub- 
membranous to chartaceous in texture, with the stipes 
about 30 cm. long, but often shorter or longer, about 3 
cm. broad or frequently narrower, pinnate often above 
the middle, uppermost segments confluent and adnate to 
the rhachis, the apical segment elongate, narrow-linear; 
free pinnae more distant and gradually smaller towards 
the base, the fertile ones slightly narrower and further 
apart; all segments linear-oblong, obtuse, margins spinu- 
lose-serrulate; sori in 1-2 rows on each side, close but 
distinct.
