130 UNDERWOOD: OUR GENERA 
(Schk.) a fern from Guiana which Moore reduces to a synonym of 
Nephrodium unitum. Cyclosorus appears to be the first name 
definitely applied to a member of the group with connivent veins 
and cordato-reniform indusia (the § Aunephrodium of Synopsis 
filicum), 
Presl included the species of Phegopteris in Polypodium, but 
Goniopteris was kept distinct. 
In 1841 John Smith * established the genus Leffogramma, 
based on seven species, of which L. asplenoides (Swz.) was first 
named. This genus, which has been placed by the Hookerian 
school in that monstrously incongruous group known as Gym- 
-nogramme, differs from Phegopteris solely in the possession of 
elongated sori and in any natural system must stand next to 
Phegopterts if not united with it. 
In 1842 Hooker and Bauer established the genus Fadyeniat 
based on the single species known from Jamaica. In this work, 
Genera Filicum, the Preslian genera were largely taken up and 
this publication represents the most sane and sound pronounce- 
ment that ever emanated from Kew on the subject of the classifica- 
tion of ferns. More species of ferns by far have been described 
from Kew than from any other center of study in the world, but 
since the publication of Genera Filicum in 1842 their utterances 07 
general fern classification have lapsed into a harmless /aisses faire 
policy a half century behind the times, and a much greater amount 
behind their magnificent opportunities in herbarium and conserva- 
tory equipment and facilities. : 
In 1846 John Smith t further established the genus Cyclopelts, 
based on a single West Indian species. His early views on genera 
quite closely coincided with those of Presl and his opinion of lox 
lationships merits particular attention since he knew growing 
ferns in cultivation probably better than any man who has aces 
lived. His later views on this group as expressed in Historia 
Filicum (1875) may be tabulated as follows (the exclusively old 
world genera in Roman type and those with American specte> ve 
small capitals) :
