var. brasiliensis n. var. 
A typo differt: stipite spinis acutis instruclis; rachi costisque subtus pilis longis 
patentibus vestitis. 
All the Brazilian specimens seen differ from the type by these two charac- 
ters; otherwise they fully agree. 
Brazil: Sta. Catharina, Joinville, O. MórLER (R) — ScHwacke nr. 13320 (C) — Am Rio Comprido bei

176. Dryopteris polyphlebia n. sp. — Fig. 19. 
Syn. Polypodium decussatum Sod. Cr. vasc. quit. 291. 1893. 
Type from Ecuador, leg. Sopiro (B, type specimen, C). 
I agree with Sopiro in considering this species distinct from D. decussata, which 
Sopiro described as a new species (P. velutinum). It resembles it in most 
characters but may be distinguished by the following 
Very large (I have not seen a complete frond); pinnz up to 45 cm. long by 
7 em broad with the costa beneath more than 2 mm broad. Pinnz oblong-ellipti- 
cal or lanceolate, shortly stalked and narrowed towards the base, in the specimens 
seen without glands. Segments close with parallel edges, their apex equally rounded 
to both sides, 3'/2 cm long by 7 mm broad; veins 50—60 to a side. Sori a little 
above the middle of the vein, oblong. — Texture coriaceous, fragile, colour grey- 
green; rachis 8 mm broad, castaneous as young very finely puberulous, soon 
glabrous. 
Besides the specimens from Equador I have seen the following from Costa 
Rica: Carillo, PrrrieR nr. 2474 (B, C, W) — Talamanca, Towpuz nr. 9453 (C, W). 
Subgenus 6. Steiropteris C. Chr. 
Biolog. Arbejder tilegnede Eug. Warming pag. 81. 1911. 
Rhizome wide-creeping, ligneous, scaly at the apex; scales firm, castaneous 
or dull-brown, entire but generally with some few short, acute hairs on the mar- 
gins. Lamina deltoid or somewhat narrowed below, rarely (in D. deltoidea) with 
several pairs of auriculiform pinne, firm to rigidly coriaceous, of a characteristic 
greyish or brownish colour, more or less pubescent by simple hairs, which partly 
are short and unicellular, partly long and pluricellular. In most species both kinds 
of hairs are found intermixed on rachis and coste beneath, in others only one 
kind is found; seldom the leaf is quite glabrous. Lamina pinnatifid, or, as a rule, 
bipinnatifid with sessile or shortly stalked pinnz, in most species with a distinct 
acute aérophore at the base. Veins simple, often raised above, those of the basal 
pair running out to the sinus, more or less connivent and with a cartilagineous
