Hymenena Kylinii Gardner sp.nov#,
�hiv.”alifornia Hll.Bot,lŤ:242Ż$1,32Ż f*lm?Ż88 f VIVI*
Fronds erect and rigid, 8-10 cm,(up to 20 OB,)bigh,
5-8 mm, wide, dichotomously or subdichotomously and
sparsely branched, with linear segments, blunt apices,
and smooth margins; usually much contorted, and the
antheridial plants more or less crisped, attached by
flattened, branched outgrowths at the base, short
stipitate;midrib becoming the stipe below, branching
into the segments above and vanishing before reaching
the apices; microscopic veinlets 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 rocks exposed to heavy surf in the lower
littoral "belt, central California, type locality, lands
End, San Francisco.

Kylin (1924, p. 63), in discussing Fymenena flabelligera
(J. Ag.) Kyi in, remarks that there are two specimens in j,ff.
Agardh's herbarium under the name of Eitophyllw flabelligerwn,
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
H. flabelligerum and likens the other to the plants distributed
in the Phycotheca Boreali Americana, no. 693 (under J. Earveyanum),
cited above. It is his 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 I. Earveyanum from " Australia." on page 81 (loo.oit.)
in discussing I.1 Harveyanum j. Ag,, Kylin 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. She illustration shows it to be very different
in general form from our plant and, as suggested by Kylin, it be-
longs to an undescribei species. I am here dedicating the species
to him. Its nearest known relative would seem to be Eymenena
flabelligera (J. Ag.) Kylin. Hhe 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.
