260 UNDERWOOD: REVIEW OF THE GENERA OF FERNS 
1791 
Schreber (Gen. Pl. 757) established the genus Meniscium 
founded on Polypodium reticulatum L. 
1792 
Richard (Ann. Soc. Hist. Nat. Paris, 114) proposed the genus 
Lophidium based on L. latifolium from Guiana. This is therefore 
the earliest name for a member of the genus Schisaea as limited 
by Hooker, and this portion of the genus may well be separated 
generically. 
1793 
Sir J. E. Smith (Mem. Acad. Roy. Sci. Turin, 5 :) established 
genera: 1. Woodwardia (411) based on four species, W. angusti- 
folia (Acrostichum areolatum L.), W. Japonica, W. Virginica and 
W. radicans. 2. Vittaria (413) based on P*erzs lineata L. 3. 
Davallia (414) based on eight species of which D. Canariensis 
(Trichomanes Canariensis L.) is first named. 4. Cyathea (416) — 
based on six species of which C. horrida (Polypodium horridum L.) 
and C. multiflora are first named, with C. arborea and C. Capensis, 
followed by such species as C. fragilis and C. montana. To show 
the liberties taken with generic types, as well as Smith's hazy con- 
ception of affinities, the first two named are now to be looked for 
under Hemitelia and the last two under Z/ix ( Cystopteris}, or in 
.other words a delicate polypodiaceous fern united generically with 
a group of tree ferns of a wholly distinct family alliance. 5. 
Hymenophyllum (418) based on Trichomanes Tunbridgense L. and 
T. asplenoides Swz. together with six others. 6. Schizaea (419) 
based on Acrostichum pectinatum L., A. dichotomum L. and A. 
elegans Vahl. 7. Gleichenia (419) based on Onoclea polypodioides 
L. and 8. Danaea (420) based on Asplenium nodosum L. and D. 
alata. Lindsaea Dryander must also be considered as published 
here (413) with Adiantum- Guianense Aubl. as a type since Dry- 
ander's paper, altho read 1794 did not appear until 1796. Smith 
is usually credited with the genus Scolopendrium but that, as we 
have seen, was used long before by Adanson. He is frequently 
credited also with Jara/zia which originated with Swartz five 
years earlier.
