The fructification of this remarkable species was unknown 
to Turner, who nevertheless was struck with its near affinity 
to F. comosus, the type of Agardh’s genus Phyllospora. The 
frond is probably of great length. Our specimens are all 
imperfect, consisting of branches and broken pieces of the 
stem, from which the habit may be inferred to be similar to 
tbat of F. comosus, namely, a long simple stem furnished with 
lateral, undivided, alternate branches, which bear a second 
and perhaps a third series of similar shorter ones; the last 
series of branches and the apices of the first, equally pro- 
ducing receptacles. "These receptacles are evidently trans- 
formed leaves. They occupy the position of the normal 
leaves, but are much smaller, the leaves being 4-5 inches, the 
receptacles 1-1} in length. The latter are cuneate and entire 
below, sharply serrated above, their upper half densely papil- 
lated on both surfaces with the globose conceptacles, which 
in our specimens contain large, dark olive, undivided spores, - a 
with a wide border. None of our specimens prod
