UNDERWOOD: REVIEW OF THE GENERA OF Ferns 263 
1801 
Bernhardi in a paper published in the pages immediately fol- 
lowing that of Swartz (Schrader's Journ. 1800':) recognized 
twenty-nine genera among which the following new ones were 
proposed: 1. Sphaeropteris * (122) based on Polypodium medullare 
Forst. from New Zealand; 2. Widelia (122) based on Trichomanes 
multifidum Forst. (Hymenophyllum multifidum Swz.) from the Paci- 
fic Isles; 3. Struthopteris (126) based on Osmunda regalis and the 
equivalent of the genus Osmunda in its modern sense; 4. Odon- 
topteris (127) based on Ophioglossum scandens L. (Lygodium 
Swz.); 5. Ripidium (127) based on Acrostichum dichotomum Forst. 
(Schizaea dichotoma Swz.) from the East Indies; 6. Gisopteris` 
(129) based on Hydroglossum palmatum Willd. (our own Lygo- 
dium palmatum); besides two genera of lycopods. He quotes 
Todea and Hydroglossum from Willd. (see below under 1802) and it 
becomes a question for the casuists whether this constitutes publica- 
tion. It will be noted that Bernhardi arrived independently at the 
same conclusions as Swartz in several cases and his results only 
lack priority of place; it is also curious to note how Swartz in his 
later publications systematically sets aside the work of Bernhardi ; 
later investigators have regarded Swartz's conclusions as unjust, 
and several of the genera of Bernhardi are now being regarded 
in their true light. 
1801 
Cavanilles (Icon. et Descr. Pl. 73)t published Ugena based on 
U. semihastata, U. dichotoma, U. macrostachya, U. polymorpha, and 
U. microphylla, thus forming another generic name for Lygodium. 
Later on Cavanilles and likewise Swartz { quote this paper as 
published in October 1801. 
1801 
Cavanilles (Description de las Plantas $) established the genera : 
I. Tectaria (249) based on Polypodium phymatodes, P. trifoliatum, 
* This has nothing to do with Sphaeropteris Wall. recognized in Synopsis Filicum 
as a valid genus.

4 Swartz quotes this portion of the work under the citation ** Prael.’’ with the date 
1801. As it cites (p. 282) the generic name Ugena, which, according to both Swartz 
and Cavanilles himself, appeared in October, 1801, this portion of the work must have
