 Type spe e i m en from Brasilia, Mertens communicavit 

 (not seen). It is, however, sure that P. deflexum Klf. is identical 

 with P. vestitum Raddi; the terms of the original diagnosis "costis 

 venisque infra paleis lacero-ciliatis tectis, soris venae adproximatis" 

 show it sufficiently. Whether Polypodium lepigerum Schrad. Gott. gel. 

 Anz. 1834: 868 is the same, as suggested in Ind. Fil., is questionable. 

 The short diagnosis agrees also with other species of this group; 

 perhaps it is identical with var. Aschersonii (see below). 



A very distinct species at once to be distinguished from allied 

 species by the very scaly rachis and eostæ and eostulæ beneath; 

 the scales are light flat, appressed, formed by large clear cells and 

 with very long hairlike fringes on the margins (fig. 3"). By this 

 last character it differs from the more scaly forms of D. submar- 

 ginalis f. vera, which are very similar D. deflexa in size and colour 

 of the scales; still D. deflexa seems to want the dense tuft of scales 

 at the base of the stipe. — Lower pinnæ reflexed ; veins about 8 

 to each side, the basal pair reaching the margin above sinus. Sori 

 inframedial, often close to the costa (A. basilare Fée), furnished 

 with a small deciduous indusium. — Leaf-tissue hairless, underside 

 sometimes slightly glandular. 



A fairly constant species, apparently common in the moun- 

 tains near Rio. I have seen the following specimens: 



Rio: Sellow nr. 680 (B); Riedel (B, H, W); Mosen nr. 97, 2704 (H, Rg), 27U3 

 (Rg); Glaziou nr. 2373 (H), 2374 (C, H, Rg); Goeldi (C); Mikan (Hb. 

 Presl).

var. Aschersonii Mett. msc. 



Differs from the type by the sessile pinnæ and persistent indusia; it is still 

 more scaly than the type, and the scales are formed by small cells with very 

 flexuose cell-walls.
