UNDERWOOD : REVIEW OF THE GENERA OF FERNS 265 
been able to discover is a note on a “ Memoire sur Ramondia, 
nouveau genre de fougére par le C. Mirbel," signed “ DC." in 
Bull. de Sciences par la Soc. Philomatique de Paris 2: 179, 
“ang” no. 47. This publication would be sufficient for the 
genus, which is only another synonym of Lygodium. 
1803 
Richard (in Michaux : Fl. Bor. Am. 2 :) established the genera: 
Nephrodium (266)* based on N. acrostichoides, N. thelypteroides, 
N. marginale, N. punctilobulum, N. bulbiferum, N. filix-foemina, N. 
asplenioides, N. cristatum, N. tenue, N. rufidulum, N. lanosum and 
N. Dryopteris : Botrypus (274) + based on B. Virginicus and B. 
lunarioides ; and Cteisium (275) based on C. paniculatum (Lygo- 
dium palmatum). He also established a sub-genus Hyfopeltis (266) 
without naming a type. 
1803 
Mirbel (Hist. Nat. Veg. 5: [ed. Deterv.]) established the 
genera Candollea (86) based on four species of which C. heterophylla 
(Acrostichum heterophyllum L.) is first named; Pyrrhozia (9t) 
based on P. Chinensis Mirbel ; Riedlea (71) based on R. sensibilis 
(Onoclea); and Belvisia (111) based on five species of which 
Acrostichum spicatum L. is first mentioned. 
: 1804 
Willdenow (Act. Holm. 165) established the genus Mertensia 
based on five species of which M. furcata from Jamaica is first 
named. Since this group is distinct from G/eichenza it is unfor- 
tunate that this generic name is preoccupied, there being a pre- 
vious Mertensia (Roth, 1797) in the Borraginaceae. 
1804 
Bory (Voy. 1: 282, note 2) published Callipteris b based on 
Asplenium proliferum, Encyc. Dict. with the statement: ‘“ Cette 
plant doit former avec quelques autres un genre nouveau," but in 
his enumeration he gives four species in the following order: 
C. castaneifolia, 2. C. sylvatica, 3. C. prolifera, 4. C. ebd
