134 DESCRIPTION OF COPTOPHYLLUM. 
between them is further indicated by both of them occasion- 
ally having part of the fertile frond barren. Coptophyllum, 
however, differs essentially from Mohria in its double row of 
sporangia, and in the want of the indusium-like, inflexed 
margin of the latter. In Coptophyllum, the annulus is much 
less developed than in any of the other genera of the tribe, 
and in this respect, as well as resembling in habit some spe- 
cies of Osmunda, it forms the connecting link between that 
family and Schizeacee. The affinities of the six genera, 
which now constitute the tribe Schizeacee, may be shown as 
follows : 
Anemia. 
Schizea. Coptophyllum. 
Lygodium. Trochopteris. 
Mohria. 
In my paper on Trochopteris, when contrasting that genus 
with Anemia, I referred to the two individuals which compose 
the present one, as being typical forms of Anemia. I referre 
so to Anemia aurita (Sw.); but without having seen the 
plant, my only knowledge of it being derived from the de- 
scription of Swartz in his Flora Ind. Occ. The very distinct 
habit of my own two plants, led me to make some inquiries 
respecting this species, and those others which form the first 
section of the genus Anemia in Sprengel's Systema Vegetabi- 
lium; all being described as having their fertile fronds 
arising distinctly from the rhizoma, and some of whichl 
thought might prove to be congeners of my two ; but neither 
in the Herbarium of Sir William Hooker, nor in that of Mr. 
Smith, do I find any of the species there enumerated. 
There are, however, three of them, figured by Plumier, and 
certainly none are Anemias. The first, A. bipinnata, SW: 
(Plum. t. 155.) is evidently an Osmunda, and perhaps not 
distinct from O. cinnamomea. The next, 4. verticillata, 
Sw. (Plum. t. 160.) is a most anomalous-looking plant, 
quite a puzzle to all who have made ferns their study. To 
me, it appears to be composed of two distinct things. What.
