Noeggerathia Sternb.—T wo of the American species are closely 
. related to N. obliqua Gipp. A third, N. Bocksiana Lsqx., which 
I referred to Cyclopteris 2 apo Gépp., from the exact likeness 
of some Neuropteris. Two of our American species, viz., Neph- 
teris fimbriata Lsqx. and Nephropteris laciniata a So have a 
typical character which has never been seen on any of the fossil 
ferns of Europe. As the names indicate, both these beautiful

fo surrounding the fruit-bearing leaves of some ferns of our

at least, the equivalent of Newropteris eordata, N. Scheumeri, N. 
angustifolia and N. acutifolia, species of M. Brongniart. A pec
