Rhizomate repente, squamis l)runneis stellato-ciliatis instructis. Stipitibus 

 quadrangularibus, griseis, ad 20 cm longis, brevissime stellato-pulverulentis et squa- 

 mis paucis deciduis onustis. Lamina ovato oblonga, 15 — 25 cm longa, medio ad 

 10 cm lata, bipinnatifida, in apicem pinnatifidum abrupte attenuata, herbacea, 

 luteo-viridi. Rachi piiis simplicibus longioribus pilis stellatis minutis intermixtis 

 sulidense lomentosa. Pinnis 9 — 10-jugis, alternis, inferioril)us reflexis, mediis hori- 

 zontalibus, sessilibus, oblongis, mediis 6 cm longis, 1' s cm latis, apice 

 abrupte acutis, rarius acuminatis, basi truncatis, inferioribus versus 

 basin parum attenuatis, supra costa excepta strigosa glabris, subtus 

 ad costas costuias venasque pilis mollibus albidis simplicibus et stellatis 

 (his brevioribus) hirtis, vix ad medium pinnatifidis. Laciniis approxi- 

 matis, obliquis, acutis, basali superiore sæpe longiore. Venis simplici- 

 bus, 6— 7-jugis, 3—4 ad sinum conniventibus. Soris medialibus, indu- 

 siis dense setosis. Sporangiis glabris. 



A small species in habit not unlike certain forms of I), mollis, 

 but venation and stellate pubescence show clearly that it belongs to 

 the group of D. lugiibris. By its reflexed lower pinnæ it resembles 

 D. lugubris var. devolvens and D. scabra, from the first it differs by its 

 small size, few veins, herbaceous texture etc., from the latter by 3-4 

 connivent veins the pinnæ scarcely narrowed towards the base and 

 less incised and in its not gemmuliferous rachis. — Further specimens:

 Type from Rio, leg. Pohl (Herb. Presl!) 



In general habit very like 1). nephrodioides and /). Eggersii but 

 well-marked by its creeping rhizome and the presence of small brown 

 scales on the rachis and costæ beneath. Stipe 20—30 cm. long and like the rachis 

 quadrangular and densely pulverulent by very short stellate hairs. Lamina up to 

 1 m long, dull-green, firmly herbaceous or membranous, the upperside throughout 

 shortly pubescent, the costæ strigose by antrorse hairs, the underside less hairy, 

 most so on costulæ and veins, the hairs generally simple; costæ beneath pulveru- 

 lent by short stellate hairs and furnished with some few stellato-ciiiate small 

 scales. Pinnæ sessile 15—18 cm long, 2';3— 3 cm broad, acute or shortly acumi- 

 nate, alternate, remote, subhorizontal, the lower ones not reflexed, their base 

 shortly attenuate in the lower, truncate in the upper ones, incised about "-/a of the
