(43) T. raecmulosuni, F. J». «., Ned. Kruidk. Arch., V, 210. 

 Rhizome short, adscendent. Stipes fasciculate, terete, the base hirsute, 



thickened, 2 — 3 c.M. long. Fronds 7 — 9 c.M. long, 2 — 3 c.M. broad, ovate- 

 lanceolate, acuminate; main rachis straight, compressed, firm, narrowly winged, 

 marginate below. Pinnae erect or erecto-patent, (the lowest largest, diva- 

 ricating), + distant, linear-lanceolate, pinnatifid, broadly cuneate at the base. 

 Pinnulae erect, distant, simple or forked, (the lowest rarely pinnatifid). La- 

 cinulae straight, short, the apex entire, circinate-convolute when dry. Texture
