Differs from the preceding in having the fronds sessile or on stalks 

 to + 4'/.^ cm. long, the pinnae (leaflets) not rai'ely more deeply lobed 

 and the lower pinnae gradually reduced to mere auricles; fronds 2() — 45 

 cm. long, + 1 — I'j^ cm. broad; the largest leaflets 6 — 7% mm. long, 

 S'/j — 4 mm. broad.

(18a*) L,. propria, r. A. ». R., in Bull. Btz., 1914, XVI, 20. 



Rhizome short-creeping, brown-flbrillose. Stipes approximate, 5 — 12'/, 

 cm. long, fibrillose at the base, finally naked, obtusely quadrangular. 

 Fronds linear, simply pinnate, 20 — 30 cm. long, 2 — 2'/^ cm. broad, 

 acuminate to subcaudate, and coarsely obliquely lobate-dentate at the 

 apex, truncate at the base. Leaflets numerous, close, horizontal or 

 nearly so, the lower remote, a little smaller than the central ones and 

 sometimes slightly deflexo-falcate, the largest 1 — 1 % cm. long, '/s — 'V/i 

 cm. broad, the apex blunt, rounded or obliquely truncate, the upper edge 

 lobate-crenate with + 3—4 lobules, the lobules when fertile truncate 

 (straight or somewhat refuse), when sterile crenate-dentate with 2^4 

 bluntish teeth, the inner edge parallel to the rachis, the lower edge 

 straight or somewhat sigmoideo-curvate. Texture thin ; rachis angular, 

 naked; surfaces naked; veins slender, not reaching the margin. Sori
