{2ie) ». barbata, ». :A. v. n., in Bull. Btz., 1918, XI, '7. 



Near D. dissecta J. S)n. but the rhizome scales black or black-brown, 

 flexuose, filiform-subulate, densely barbate-ciliate, narrowed suddenly from 

 a suborbicular, adpressed, peltate base, the ciliae pale-ochraceous ; fronds 

 relatively small; fertile lobules sublanceolate-clavate from a cuneate or 

 linear base; indusium semicylindrical, + 2'/^ — 3 X as long as broad, 

 generally with 1 — 2 often elongated teeth projecting beyond, the apex to 

 1 mm. distant from the margin of the lobule, truncate or somewhat 

 rounded. — Differs from D. buUata Wall, by its much longer sori.

(2if) D. Piillei, Rst., in Nov. Guin., VIII, Bot., 719. 



Rhizome creeping, woody, pruinose, clothed with lax, ferrugineous, 

 lanceolate, acuminate scales. Stipes remote, 3 — 5 cm. long, sulcate above, 

 provided with scattered, short, spreading, brown hairs, as are the rachises 

 and both surfaces. Barren fronds triangular or ovate, ± 8 — 10 cm. long, 

 5 — 6 cm. broad at or near the base, acuminate. Pinnae subapproximate, 

 the lowest opposite, obhquely triangular, ± l'/^ cm. broad, horizontal or 

 spreading, acute or acuminate, produced on the lower side at the base. 

 Pinnulae close, the lowest cut down to the rachis into close, erecto-patent, 

 cuneate-oblong, deeply inciso-dentate segments to 3 mm. long; ultimate 

 lobes (teeth) triangular, close, spinuloso-acuminate, connected at the base. 

 Texture rigidly coriaceous. Fertile fronds similar but the ultimate 

 segments not close, oblong in the upper half, narrowly Unear (substipiti- 

 form) in the lower half. Sori occupying the dilated region of the ultimate 

 segments; indusium nearly semicylindrical, + twice as long as broad, 

 the apex rounded or subtriangular, reaching the margin of the 

 segment, with 2 very sharp and long, subuliform horns beyond, which 

 are different in length.

Sori roundish or oblong, solitary ai or near the base of the ultimate 

 teeth or lobes, terminal on the veins or veinlets; indusium partly as in 

 Humata or Davallia partly as in Leptolepia.
