Nephrodium bermudianum, Baker, n. sp. (Plate XIII.) 



Nephrodium bermudianum, Baker, n. sp. 



Rhizomate breviter reptante, stipite semipedali supra basin hand paleaceo, fronde 

 oblono-o-lanceolato subpedali modice firmo parce piloso, rbachi stramineo dense piloso 

 baud paleaceo, pinnis sessilibus vel subsessilibus lanceolatis multijugis patulis ad 

 medium pinnatifidis inferioribus basi posteriore reductis, segmentis secundariis oblongis 

 integris contiguis, venis regulariter pinnatis venulis 5-7 jugis simplicibus raro furcatis, 

 soris parvis medialibus, involucro minute reniformi. 



A near ally of the West Indian Nephrodium asplenioides, Baker. Central piunse 

 2 to 2ij in. long, ^ to f in. broad, the lowest of the frond sometimes but not always 

 dwarfed ; final segments, fe to \ in. broad ; veins always simple, except in the anterior 

 segment of the lower pinnae, which is often larger than the rest. 



Bermudas. — Endemic. Near Paynter's Vale — Farlow; without locality — Lefroy. 



The plant named Polypodium (Goniopteris) tetragonum, Swartz? (Trimen., Journ. Bot. 

 1877, p. 367), collected by the Rev. R. Hunter at Walsingham, is most likely, Mr Baker 

 informs us, this species, which appears to be endemic in the Bermudas.
