Haviiig exainined the «nany received spécimens of this species, espec- 

 cially of the var. setulosa, I am now convinced that this species has no 

 spurious indusium and that the whorl of hair-like fibres encircling ihe base 

 of the réceptacle, drawn in Hooker's Species Filicum, I, tab. XVIII. fig, 2 as 

 a deeply fimbriated spurious indusium, is but a continuation of the nume- 

 rous fine, hair-like paraphyses with which the capsules are intermixed. — We 

 can see similar whorls of hairs or fibres aiso in A. squamulata and tomen- 

 tosa Hk., and other species that are likewise provided with paraphysate sori. 



Omit \he v'dùfily persquamulifera, wh\ch is A. persquamuliferav. /l.v. /?.— 

 Var. longepaleata Christ, of Celebes, with a long-scaly rachis, is perhaps a 

 distinct species.

Stipe and main rachis castaneous or dark-fuscous, glabrescent, copiously 

 tuberculato-aculeolate like the secondary and tertiary rachises. Pinnae 

 H- 50 cm. long, the rachis above ioîig-ferrugineo-viilose, otherwise deciduously 

 scaly; scales long-linear, acute, rufous or ferrugineous, acutely and shortly 

 castaneo-ciliolate, intermixed with scattered, deciduous, short, castaneous 

 hairs and copious deciduous, very minute, lacerate, furfuriform, ochraceous 

 to ferrugineous squamules. Pinnulae sessiie, 10— 12'/2 cm. long, l'/2— 2V2 

 cm. broad at the truncate base, acuminate, deeply pinnatipartite or pinnate; 

 Costa (tertiary rachis) glabrescent above, beneath copiously scaly in the 

 lower part, copiously hairy in the upper part; scales like those of the 

 secondary rachises, hairs like those of the costules, both passing gradually into 

 each other. Segments free or connected at the base, linear-falcate, blunt, 

 crenulate at the recurved edge; costules copiously long-hairy beneath, of 

 the lower segments scaly at the base; hairs ochraceous to ferrugineous. 

 articulated, intermixed with few ciliate, acuminate, bullate squamules of 

 the same colour. Texture coriaceous; veins naked, once or twice forked. 

 Sori inframedial on the veins; capsules intermixed with fine, hair-like 

 \^ paraphyses.— Near A. tomentosa Hk.
