hairs, mostly confined to the margins, upper surface spai-ely, under one

Glaziou 18687. 



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



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

Glaziou 4411. 



Polypodiuin nosenii n. sp. {Goniophlehluni). 



Rhizome 1 — 1\2 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 

 7^/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 pinnae 2 dm. long by :2 cm. broad 

 the lower ones not deflexed or reduced; pinnte 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 areoles 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.
