(20c) A. gtiinctulata, ». A. ». R., in Bull. Btz., 1915, XX, 5. 



Stipes fuscous when dry, aculeate with short, acutely conical warts, 

 deciduously squamuloso-furfuraceous, scaly towards the hase, the tomentum 

 rufo-fuscous, the scales long, subulate-lanceolate, rufo-fuscous, very minutely 

 eroso-denticulate. Fronds 3-pinnatifid, sub-3-pinnate, the main rachis 

 muricato-asperous, above grooved and villoso-tomentose in the groove, 

 beneath densely punctulate and, when young, probably furfuraceous. 

 Pinnae stalked, subhorizontal, 65 — 70 cm. more or less long, acuminate, 

 the rachis subcastaneo-villoso-tomentose above, copiously punctulate and 

 deciduously subferrugineo-furfuraceous beneath. Pinnulae numerous, ap- 

 proximate, linear-lanceolate, acuminate, the higher oblique, the lower 

 horizontal or deflexed; medial or inframedial pinnulae largest, short-stalked, 

 13 — 14 cm. more or less long, 2% — S'/j cm. broad below the middle, 

 acuminate, deeply pinnatifid, nearly pinnate, slightly narrowed at the 

 more or less truncate base, the costa villoso-tomentose above, deciduously 

 furfuraceous and squamulose beneath. Ultimate segments linear, more 

 or less falcate, the largest to 1'/, cm. long, about 3 mm. broad, bluntish 

 or subacute, the edge recurved, dentate-crenate ; higher segments rather 

 approximate, lower more remote and often free and more or less 

 abbreviated; costulae naked above, squamulose beneath, the scales partly 

 bullate, partly lanceolate; veins to 12 — 15 on a side, forked, the higher 

 simple, the lower not rarely 3-furcate. Texture coriaceous; surfaces naked; 

 upper surface dark-olivaceous when dry, lower paler. Sori inframedial on 

 the veins, contiguous, to 8 — 10 on a side, the receptacle encircled by a 

 very minute, brown, erose scale.

Trunk slender, to 5 m. or more high. Stipes about 35 cm. long, 

 muricato-asperous in the upper part, scaly, and aculeolate with short, 

 acute, conical warts towards the base ; scales deciduous, narrowly subulate, 

 "fuscous, more or less eroso-denticulate, and remotely ciliated with short, 

 erect, red-brown hairs. Fronds 3-pinnatifld, acuminate, the main rachis 

 ■muriculato-asperulous towards the base, and, like the secondary ones,
