Rhizome rather ascending, woody, the extremity clothed with rather 

 ong, apiculate, castaneous scales. Stipes close, ± 50 c.M. long, long-winged, 

 ;he unwinged base ± 5 c.M. long, the wing ± 1 '/j c.M. broad. Fronds 

 50—80 c.M. long, ovate in outline, pinnatifid. Lobes ± 5-jugate, ovate, spread- 

 ng, ± 30 c.M. long, ± 10 c.M. broad, acuminate, entire, distinctly nar- 

 'owed at the base, the costal wing I'/j — 3 c.M. broad. Texture coriaceo-pa-

 fVIII, 16; Aspidium penlaphyllum, «. A. v. R., 1. c. 



Stipes ± 30 c.M. ,long, like the rachis brown or blackish-purpureous, 

 oinutely fibrillose and deciduously scaly, the scales few, scattered, lanceolate- 

 ubulale, brown or purpureous. Fronds 30 — 45 c.M. long, 16 — 25 c.M. broad, 

 irith a terminal pinna and 2 lateral ones on each side. Terminal pinna 

 S — 20 c.M. long, simple, broadly ovate, acuminate, the edge undulate with 

 ounded or sharp lobes, the base broadly cuneate or rounded, not rarely 

 urveyed with 1 — 2 lanceolate, bluntly rounded or acuminate, erecto-patent 

 Bgmenls. Lateral pinnae erecto-patent, distant, broadly lanceolate, unequal- 

 ided, the lower side broader than the upper, the apex acuminate, the 

 Ige entire or undulate, the base broadly cuneate to rounded; lower pinnae 

 fith an oblong or sublanceolate, blunt or acuminate lobe at the base on the 

 iwer side. Texture subcoriaceous, subpellucid; costae and main veins promi- 

 ent ; veins visible ; areolae numerous, with free veinlets ; surfaces naked. Sori 

 umerous, scattered irregularly, often confluent. — According to Copeland's 

 mception of the generic name this plant should be called Tectaria pentaphylla,
