Gelidium pulchrum Gardner, sp.nov.
Univ.Calif.Publ.Bot.13:279.pi.50-53. 17 Mr 1927.
Fronds 15-20 cm. high, 300-500Ż diam..almost cylin-
drical below, becoming gradually flattened toward the
upper parts; branching distichous, of 5-6 orders, each
order reduced in size, alternate or opposite, with re-
latively acute apices; cystocarps mostly single in the
center of short, acute, fructiferous ramuli; tetrasporangia
terminal on short, blunt, ultimate ramuli; antheridia on
longer ramuli quite variable in diameter in different parts;

Gelidium austral? Collins, Holden and Setohell, Phyo.Bor.
Amer. (Exsicc.), no. 586.
This is a beautiful and rather slender species of
Gelidium, purplish-red to pink in color, as far as is known
at present, its distribution is limited to southern California.
The type locality is Laguna Beach, Orange County.
This species on the Californian coast has passed under the
name of G. australe J. Ag. I have compared our material with
an apparently authentic specimen of this species from the
herbarium of J.G. Agardh, now in the herbarium of the university
of California, no. 93585, collected at Lacepede Bay, on the
southern coast of Australia. This specimen is illustrated on
plate 44. As may readily be seeni the branches of all orders are
much more flagellate and tapering, closer together, more frequent-
ly opposite than in G. pulchrum, and are cylindrical throughout
instead of being flattened.
