8. Nephrodium paucijugum Jenman, Journ. Bot. 1886: 270; Dryopteris chartacea 
C. Chr. Ind. 257 — Jamaica, SHERRING. 
On this see Maxon Contr. H. S. Nat. Herb. 10: 489. I believe that the 
type-specimen of it is at Kew, and I have seen it. It is sterile and undeter- 
minable. It is not improbable that JENMAN was right in considering it a 
young plant of D. oligophylla. 
Subgenus 8. Leptogramma J. Smith emend. C. Chr. 
Biolog. Arbejder tilegnede Eug. Warming pag. 82. 1911. 
A small group, in America represented by three species. I confine it to 
include the species of Gymnogramme § Leptogramma of Syn. Fil. only having more 
or less soft-hairy lamina, oblong to linear, exindusiate sori and setose sporangia. 
The lamina is not or slightly narrowed downwards, the rhizome generally long- 
creeping, at apex furnished with few hairy scales. The hairs of most species are 
long, thin, pluricellular. In general habit and venation the species resemble 
mostly species of Cyclosorus, thus the American D. pilosa and D. dasyphylla, while 
the third D. polypodioides comes very near to species of Goniopteris, but I have not 
found stellate or forked hairs, which constantly are to be found in species of 
Goniopleris. — The typical species of Leptogramma is the common D. africana 
(Desv.) C. Chr. (Gymn. tolla Schlecht.) from Africa and Asia.
