plicibiis, utrinqae 9 - U. Sori parvi, ad veiias + terminales; 

 indusium rotundatiim, i. e. reniforme, lobis basalibus sese tegentibus. 



Forma confertiloba: Lobi fertiles conferti vel subcontigui,

Forma laxiloba: Lobi fertiles remoti, basi distincte dilatati. 



Stipes ca 30 — 45 cm. long, pale-brovvn. i;'labroLis at least in 

 the fally developed fronds, the base clothed with moderately 

 long, brown, subulate, entire scales. Fronds to 40 cm. long or 

 longer, ca 25 — 30 cm. broad. Pinnae ca 1V2-1'V4 *^ii^- broad, 

 acuminate, the central ones the largest, truncate at the base, 

 the lower somewhat deflexed, slightly abbreviated, narrowed 

 towards the base. Lobes entire. Rachis naked like the stipe; under 

 surface apparently glaucous by the minute vestiture, the stipe 

 and rachis more or less so. — Near D. patens 0. Ktze.

 segmentis ultimis erecto-patentibus, maximis usque ad 5 mm. 

 longis et 2 mm. latis dentatis, dentibus modice longe et auguste

Near H. botrychioides Brack. and vestita Moore but with 

 the soriferous teeth very blunt, short and broad; scales of the 

 fronds similar to those of the rhizome but shorter and paler, 

 caducous in the barren, more persistent in the fertile fronds; 

 sori occupying the whole underside of the teeth.
