Type specimen from Brasilia, MERTENS communicavit 
(not seen). It is, however, sure that P. deflecum KIf. is identical 
with P.vestilum Raddi; the terms of the original diagnosis “costis 
venisque infra paleis lacero-ciliatis tectis, soris venae adproximalis" 
show it sufficiently. Whether Polypodium lepigerum Schrad. Gótt. gel. 
Anz. 1824: 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 cost and costule 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 pinnz 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); RiepEL (B, H, W); Mosén nr. 97, 2704 (H, Rg), 2703 
(Rg); Graziou nr. 2373 (H), 2374 (C, H, Rg); GoErp: (C); Mikan (Hb. 
PRESL). 
Parahyba: Gozrpni (C). 
var. Aschersonii Mett. msc.

Differs from the type by the sessile pinnze and persistent indusia; it is still 
more scaly than the type, and the scales are formed by small cells with very 
flexuose cell-walls.
