Eymenena Kylinii Gardner ep.nov,
IJniv,California Tubi.Bot.12:242.II.22. f.1-2,28 F 1927
AJ***
Fronds erect and rigid, 8-10 cm.(up to 20 tm.jhigh,
5-8 mm. wide, dichotomously or subdiohotomously and
sparsely branched, with linear segments, limit apices,
and smooth margins; usually much contorted, and the
antheridial plants more or less orisped, attached by
flattened, branched outgrowths at the base, short
stipitatejmidrib becoming the stipe below, branching
into the segments above and vanishing before reaching
the apices; microscopic ye inlets absent or rare; cystocarps
distributed over the segments without order; antheridia
confined more generally in irregular sori near the apices
and along the margins; tetrasporangia arranged in narrow,
longitudinal or in part flabellar, anastomosing sori.
Growing on rooks exposed to heavy surf in the lower
littoral belt, central California. 2type locality, lands
End, San Francisco.

Bor.-Amer. (Exsicc.) no.- 692.
Xylin (1924, p. 83), in discussing Eymenena flabelligera
(J. Ag.) Kyi in, remarks that there are two sped mens in J.G.
Agardh's herbarium under the name of Hitophyllm fl&helligerm,
J. Ag.,collected by Berggren in the Golden Gate, California.
In figure 68 (loo.oit,)hhe presents an illustration of these
two specimens, one of which is several times larger than the
other. He considers the larger of these as the type of Agardh's
I. flabelligerum and likens the other to the plants distributed
in the Phycotheoa Boreali Americana, no. 693 (under fl, Harveyanum),
cited above. It is hia opinion that the plants of this dis-
tribution, which are from the type locality of the above mention-
ed plants in Agardh's herbarium, are not identical with the
material of U. Harveyanum from " Australia." On page 81 (loo.oit.)
in discussing I.' Harveyanum j. Ag., Eylin states that the type
specimen of this species is in Agardh's herbarium, that it is a
tetrasporio plant, and that the tetrasporio sori are distributed
over the middle parts of the frond. Figure 65 (loo.oit) represents
this type specimen, fflie illustration shows it to be very different
in general form from our plant and, as suggested by Kyi in, it be-
longs to an undesoribei species. I am here dedicating the species
to him. Its nearest known relative would seem to be Eymenena
flabelligera (J. Ag.) Xylin. The most striking resemblance be-
tween these two species is the flabellate arrangement of the
tetrasporio sori. I. Kylinii is very much smaller and less com-
plex In branching than H. flabelligera and different In general
habit, the former being muol more rigid and contorted.
