Near P. aJhklidum Bak. bat differs by its pilose stem and frond, by 

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

Glaziou 4411. 



Polypodium .Vosenii n. sp. (Goniophlebium). 



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, fuhy 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.
