Has. New Holland; New Zealand. Raised in 1838. 
Oss. Representatives of this species are found very generally 
throughout the tropics and extra-tropical regions of both hemi- 
spheres ; and, as they present some peculiarities both in habit and 
venation different from the genuine species of Litodrochia, I 
think they may, with some degree of propriety, be constituted 
into a separate group, under the title of Agardh’s sectional name 
Listiopteris.

Oss. There appears to me to be an interminable confusion of 
synonymes as regards this species, which I find impossible to quote 
with any degree of satisfaction ; it is sufficient to know that the 
specimens now before me are identical with the specimens in the 
Linnean Herbarium. Plumier, fig. Tab. 15, is quoted for this 
species, but in my opinion that figure as correctly represents 
another West Indian species which is only known from the 
present by the difference in venation, the present having (agree- 
able to the generic character) the lower pairs of venules anasto- 
mosing, whereas, in the other species alluded to, the veins are all 
free, and, as Plumier’s figure does not represent the venation 
satisfactorily, it is difficult to say to which it ought to be referred. 
2. C. nemoralis, J. Sm. Pteris nemoralis, Willd. : 2 
Has. East Indies. Received from the Royal Botanic Garden of Berlin 
in 1841. 
Oss. In my ‘ Enumeration and Characters of the Genera of 
Ferns’, I did not consider Campteria of Presl, to be sufficiently 
distinct to merit a separate genus, but I now admit it solely on 
the grounds that it may be considered to form the transition 
from the free venation of true Péeris, to the reticulated form that 
characterizes Litobrochia.
