Cladophora flexuosa	.) Ha rv. forma Floridana n.f.
"Sollins, Hhodora 13:106. 1906.
More slender than the New England form represented by Far-
low, Anderson & Eaton, No. 206, and with more virgate, less div-
ided branches; somewhat resembling Cy Bertolonli var. hamosa
Ard. of the Mediterranean. On rocks, Key West, Florida, Ifarch,
1897.

Subsequent study of this plant by Mr. Gardner, indicates that
its affinities may be with the OvanoDhvceae rather than with the
Chloro phvceae.
I	am indebted to Dr. 12. Bornet for calling my attrition to
the resemblance between this plant and _C. polyacantha Montagne,
Ann. Sci. Nat.Series, 3? Bot. Vol.XIV, p. 283” from Guiana, and
for a fragment of an authentic specimen; the numerous slender,
spine-like, largely opposite ramuli are characteristic of both,
and it now seems safe to refer the Florida plant to Montagne*s
species.
