﻿Gilbert : Revision of the Bermuda Ferns 601 



_-l in. wide with very short petioles, lower pinnae variable, 

 usually slightly reduced but sometimes largest, cut halfway to the 

 midrib, very blunt, point entire, dark green on upper side and 

 somewhat canescent, paler on under side : segments uneven in 

 length, blunt, close, entire, basal segments on one or both sides 

 enlarged, texture subcoriaceous : veins beneath pilose, regularly 

 pinnate, 5-7-jugate, lowest veinlets uniting and sending a vein to 

 the sinus as in Eu-Nepkr odium, simple in smaller specimens and in 

 upper half of frond, but in larger and more mature specimens 

 forked from the middle on inner half of pinnae often uniting at the 

 edge and forming a pentagonal areole, thus bringing the species 

 into the Pleocnemia section : son small, situated on middle of vein 

 when latter is simple, and at or just above the fork on the anterior 

 veinlet when branched ; involucre small, reniform, fugacious. 



Mr. Baker places this in Eu-Nephrodium, but the probability is 

 that his specimens were not fully developed, although the frond 

 figured in Voyage of H. M. S. Challenger seems to be nearly full 

 sized. The venation of the figure, however, is quite indistinct and 

 does not convey a correct impression of the fern. There seems 

 to be no doubt that it belongs in Pleocnemia, and in that light it 

 becomes a highly interesting form, since there is but one species of 

 that section reported as belonging to the western hemisphere, viz., 

 P. dissident from Porto Rico, which Mettenius originally described, 

 but which neither Hooker nor Baker had ever seen. 



It should be mentioned that Governor Lefroy supposed this 



Neph 



Nephrolepis exaltata Schott. 



Given by all authorities and common among rocks in the Wal 



singham district. 



Polvpodium Plumula H.B.K.

Both Lefroy and Hemsley give this species under the latter 

 name, and I found it at Paynter's Vale, the locality named for it by 

 Hemsley. Lefroy says it is « found chiefly in the WaLsmgham 

 tract and not very common." It grew very sparingly tins year 

 and the weather had been so dry that the fronds were curled .so 

 that it was difficult to make good specimens of them, thus justify-
