964  Unperwoop: REVIEW OF THE GENERA OF FERNS 
P. filix-mas, P. filix-foemina and other species described as new 
from Spanish colonies; 2. Oleandra (252) based on a single 
species, O. neriiformis; and 3. Humata (272) based on three 
species described by Cavanilles from the Marian Isles, vis. H. 
ophioglossa, H. pinnatifida and H. trifoliata. 
1802 
Bernhardi (Schrader’s Journ. 1801': 22) founded the genus 
Calypterium based on Onoclea sensibilis L. 
1802 
Cavanilles (Generos y especies de plantas demonstradas en las 
lecciones publicas del afio de 1802*) established two additional 
genera: Clementea (553) based on a single species from the Marian 
Isles, which is evidently the exact synonym of Axgiopteris evecta ; 
and Aphyllocalpa (556) based on Osmunda regalis, the genus 
Osmunda being reserved for O. Lunaria and other species of Botry- 
chium, as had been done by Bernhardi a year earlier. In his sum- 
mary at the close of the work he recognizes twenty-eight genera 
of ferns. 
1802 
Willdenow (Act. Acad. Erford. 14 f) established the genera 
Todea, based on Acrostichum barbarum L., and Hydroglossum, 
based on Ophioglossum scandens L. and seven other species. 
1802 
Mirbel established the genus Ramondia based on R. flexuosa 
and A. scandens. The only reference to this publication we have 
— late in the year 1801, if, indeed, it was not issued early in 1802, the date cited 
oore for these genera. Pp. 285-625 evidently appeared later in 1802, The 
versity and Kew Herbarium, the title page is dated 1827, but hog evidently has nothing 
to do with the text of the book itself, and, according to Pritzel, belongs merely to the 
reprint edition of the work. dee full title of the work is ** Disciption on de las plantas
