are, however, glabrous and only in a single specimen have I found a few sporangia 

 with one or two hamate hairs. 



The following variety is connected by intermediate forms with the type: 



var. subhastata n. var. 



Peru: Tarapoto, Spruce n. 3964 (HH. HB). — Loreto, E. Ule n. 6518 (HC). — 

 St. Gavan, Lechler n. 2311 (HB).

Venezuela: Caracas, E. Otto n. 5% (HB). 



A typo difîert: pinnis subhastatis, i. e. basi superiore auriculata, sursum

Under this name I unite two forms hitherto considered as two different species; 

 the older name asplenioides is not available within the genus. In size, habit, texture, 

 pubescence etc. the two forms agree exactly with each other; the diffei-ence between 

 them is mainly the different shape of the sori, but this difference is rather vague; 

 asplenioides has often many round sori and in ptarmica the larger sori are generally 

 somewhat elongated. I therefore consider ptarmica an indusiate form of asplenioides; 

 the indusium is very small and difficult to find. 



1. ptarmica: Soris plerumque rotundis, indusio minimo, ciliato, mox deciduo 

 instruclis — [Fig. 14]. 



Type from Brazil, leg. Sello (HB!); also from S. Paulo, leg. Wacket 

 n. 58 (HR). 



2. asplenioides: Soris + elongatis, exindusiatis.

Type from Brazil, leg. Freyreis (HS!). Besides this I have seen numerous 

 specimens from southern Brazil (for instance Glaziou n. 930, 1784. 5324, Mosen 

 n. 2235 (HH)), all agreeing exactly with the type specimen. 



The species is certainly a near ally of D. aspidioides, but its habit is different 

 and it is probably confined to South-Brazil, while D. aspidioides is an andine species. 

 It is smaller (pinnæ about 3 cm. long by 6 — 8 mm. broad) of thinner texture and 

 darker colour, stipe squamose, pinnæ with cuneate base, incised '-k — '-h of the way 

 down with very oblique lobes; veins about 3 to a side. 



Polypodium saxicola Sw. Vet. Akad. Handl. 1817: 59 tab. 3 fig. 5 from Brazil, 

 leg. Freyreis (HS!) is probably a form of this species. The original specimen is in 

 poor condition and I cannot venture at present to unite it with Ü. ptarmica. Swartz' 

 figure is not good. The sori, especially the basal ones, is oblong almost as in
