hairs, mostly confined to the margins, upper surface sparely, under one 

 densely white-pruinose. 

 Glaziou 18687. 



Near P. albidulum Bak. but differs by its pilose stem and frond, by 

 the segments being again lobed, and by its more rigid texture.

Glaziou 10177, 15753. 



Probably included under P. trichomanoides Sw. by Baker in „Flora 

 brasiliensis", and, 1 think, only a dwarfed variety of this species.

 Brés. 2, 54, tab. 97, fig. 1, non Karst. Flor. sel. Columbiæ~tab.*144). 



Frond clothed throughout with long, patent, reddish hairs; texture 

 very thick, costa and veins invisible. 



Glaziou 4411. 



Polypodium Ilosen ii n. sp. {Goniophlebium): 



Rhizome 1 — 172 cm. thick, creeping, scaly; the scales are numerous, 

 persistent, imbricated, adpressed, ovate, short acuminate, large (6 mm. long- 

 by 3 mm. broad), peltately fixed and dark red-brown or nearly black with 

 transparent light-brown edges, very thick and rigid. Stems at distances 

 of 4 cm., brownish or stramineous, glabrous, 3 — 4 dm. long. Frond 

 I 1 1 2 — 8 dm. long, lanceolate oblong, fully pinnate but with a pinnatifid 

 apex. Rachis above sulcate, slightly hairy and clothed below with scat- 

 tered dark-brown, ovate, long acuminated, ciliated, thin and reticulated 

 scales with a cordate base. Largest pinnæ 2 dm. long by 2 cm. broad, 

 the lower ones not deflexed or reduced; pinnæ numerous, 35— 40 jugate, 

 nearly opposite, in the lower half of the frond at distances of 2 — 3 cm., 

 lanceolate, entire, often falcate, acute or acuminate, sessile; upper side of 

 the base a little dilated and adnated to rachis, the lower one free, rounded; 

 midrib stramineous; both surfaces naked except the lower third of the 

 midrib below, which bears a few scales like those of the rachis but smaller; 

 veins distinct, forming 4 or 5 rows of aréoles between the midrib and 

 edge, the free veinlets ending in a white calciferous dot on the upper 

 surface, when not soriferous ; sori round, superficial, in 2—3 rows on 

 both sides of the midrib; texture herbaceous.
