UNDERWOOD: REVIEW OF THE GENERA OF FERNS 269 
1811 
Aub. du Petit Thours (Melanges de Botanique, 1 :) founded the 
genus Scyphofilix with no type mentioned, but described as follows : 
* Involucrum calicinum cupuliforme, continens plurimas capsulas 
annulatas, disco folii inferiore adnatum frons decompositas. An 
Davallia Smith? ;" and Vallifilix based on Ophioglossum scandens. 
The author considers it necessary to establish this last genus as 
new, altho he quotes Lygodium Swz., Ugena Cav., Odontopteris 
Bernh., Ramondia Mirbel, and Hydroglossum Willd. as synonyms 
most of which were founded on exactly the same type! If ever a 
genus was overburdened with synonyms it is the genus Lygodium ; 
almost every writer on ferns in the first decade of this century gave 
it a new name. 
1813 
. .R. Brown (Trans. Linn. Soc. 11: 173) republished* the genus 
Woodsia based on W. /lIvensis and W. hyperborea, the latter need- 
lessly coined by Swartz, as both he and R. Brown cite Acrostichum 
alpinum Bolton as the original name. 
1816 
Lagasca (Gen. et Sp. Pl. 33) established the genus Z/avea 
based on ZL, cordifolia from Nova Hispania. 
1819 
Raddi (Op. Sc. di Bol. 3:) founded the genera O/fersia (283, 
pl. 6) based on O. corcovadensis from Brazil and Rumhorat (499, 
pl. 12. f.) founded on R. aspidioides from Brazil. 
1820 
Kaulfuss (Berl Jahrb. Pharm.) established the following 
genera: 1. Xiphopteris (35) based on Grammitis serrulata and 
G. myosuroides from Jamaica ; 2. Cochlidium (36) based on Gram- 
mitis graminoides Swz. from Jamaica ; 3. Onychium (45) founded 
on “nur eine Art vom Vorgeberge der guten Hoffnung " ; since 
* Prodr. Fl. Nov. Hall. 1 : 158, note. 1810. 
+ Evidently a misprint for Rumohra as it was named for C. de Rumohr.
