In its most developed form a very distinct species but in minute characters 

 not essentially different from D. nigrovenia and Ü. Lindeni. Stipe, rachis and costæ 

 beneath with many, castaneous, narrow scales, which have a broad, but scarcely 

 buUate base and a long filiform apex, which is sometimes ciliated. Stipes fasci- 

 culated from an erect rhizome, 25—35 cm long, castaneous, glossy. Lamina deltoid, 

 20 — 30 cm long, firmly herbaceous, dark-green, glabrous, nearly tripartite in the 

 most developed form. Basal pair of pinnæ much the largest, up to 15 cm long, . 

 bipinnatifid , their basiscop pinnulæ much enlarged, 4— 6 cm long; incised nearly 

 to the costa into oblong, acute, entire or faintly toothed segments, their acroscop 

 pinnulæ smaller often only 1 or I'/s cm long, sometimes not quite free, serrated or 

 lobed halfway down to the midrib. Other pinnæ pinnatifid or fully pinnate at 

 the base, 6—8 cm long, 2 — 2^2 cm broad, equal-sided, their segments acute, entire 

 or toothed in the outer part. Veins 5—8, simple, reaching the margin. Sori infra- 

 medial, small, apparently exindusiate.

Polypodium fibrillosum Bak. Syn. 307. 1867. 



Dryopteris fibrillosa C. Chr. Ind. 264. 1905. 

 Type from Peru, prope Pampayaco, leg. Poeppig. — I have not seen an 

 authentical specimen of the type-collection, but the three figures of Ettingshausen 

 quoted above, which agree excellently with the descriptions of Kunze and Mette- 

 Nius, illustrate a form that is quite identical with a specimen in Herb. Mus. Paris 

 of Spruce's collection nr. 4772 from Tarapoto, Peru, the type-number of P. fibril- 

 losum Bak. The same form was collected in Bolivia, Antahuacana, O. Buchtien 

 nr. 2191 (R). 



Stipe below densely clothed with patent 1—2 cm long, narrow and acute, 

 castaneous or black-brown, faintly toothed scales. Pinnæ opposite, short-stalked, 

 10 cm long by 3 cm broad, at distances of 6—7 cm, the lowest pair deflexed with 

 their lower side somewhat enlarged. Rachis and costæ beneath furnished with 

 several, narrow, linear- acuminate, black-brown, faintly toothed scales (fig. 3"), 

 costæ on both sides sparsely hairy or almost glabrous, surfaces otherwise glabrous. 

 Texture firmly herbaceous, colour brownish, leaf-tissue finely pellucido-punctate. 

 Segments broad, obtuse, shallowly répand or crenate, the basal posterior one of the
