(81&) D. verruculosa, «. A. v. n., in Bull. Btz., 1913, XI, 12. 



Rhizome moderately short-creeping, black-brown, the scales brown, 

 deciduous. Stipes subapproximate, + 10 — 30 cm. long, slender, hairy, 

 more or less glabrescent towards the base, those of the fertile fronds the 

 longest. Fronds + 10—20 cm. long, with a terminal pinna + 8 — 15 

 cm. long by 2 — S'/i cm. broad and 1 — 2 similar but smaller lateral ones 

 on each side. Pinnae lanceolate, acuminate, entire or broadly and 

 shallowly crenate, rounded or cuneate at the base, the lateral ones 

 sessile, erecto-patent, alternate, with the costa provided with a hardly 

 elevated gland at the base beneath, the fertile ones smaller than the 

 barren. Texture herbaceous; rachis and costae hairy; surfaces minutely 

 but copiously verruculose; under surface very minutely deciduously 

 hairy; areolae in ± 6 — 9 rows between the costa and margin. Sori 

 minute, in 2 rows between the main veins, round, rarely confluent; 

 indusium caducous, probably minute or rudimentary. — Resembles in
