Bermudas. — Indigenous. Sea beach, Walsingham — Lefroy ; Ireland Island — Reade. 



Nearly all tropical and some sub-tropical regions, but much more abundant in the Old 



World than in America. 



EQUISETACE.E. 

 Equisetum, sp. 



Equisetum, sp. 



Bermudas. — Indigenous. Pembroke Marsh — Lefroy. 



We have seen no specimens of this plant, which was determined by Mr Sargent of 

 Harvard. It is likely to be the Equisetum bogotense, Kunth. 



FILIOES. 

 POLYPODIES. 



Adiantum bellum, Moore. (Plate XI.) 



Adiantum helium, Moore in Gard. Chron., n.s., xi. p. 172. 



Adiantum capillus-veneris of Jones and Rein's list, but not of Linnaeus. 



Bermudas. — Indigenous. Abundant all over the islands — Rein; Jones; Moseley; 

 Lefroy. 



If this is to be regarded as a distinct species, it is endemic in the Bermudas ; but Mr 

 J. G. Baker named the specimens collected by Mr Moseley Adiantum cuneatum, Langs, 

 and Fisch., which species is a native of Brazil and Uruguay, and we think the Bermudan 

 plant is not specifically different. Indeed, the specimens of Adiantum cuneatum from the 

 southern part of its area are scarcely distinguishable from the Bermudan. 



Moore's description is appended : — 



"Fronds tufted, 3 to 6 inches high, bipinnate, ovatodanceolate ; pinnae of 3 to 6 

 pinnules, \ to 1^ inch long, stalked ; pinnules cuneate or irregularly transverse-oblong, 

 the somewhat larger terminal ones cuneate and divided into two or three shallow lobes, 

 the margin erose, all shortly pedicellate, the pedicels hair-like, not articulated with the 

 pinnule, but showing at their apex a short y-shaped ebonous furcation, which passes into 

 the flabellate venation ; sori various, two or three on the smaller pinnules, short and 

 roundish or longer and sublimate, situate at the apex of the shallow lobes; indusium 

 entire. Caudex thin, shortly creeping with criniform scales ; stipes and rhachises 

 ebonous, smooth." 



The wild specimens in the Kew Herbarium are at least double the size described by
