114 University of California Publications in Botany [Vol. 6 



Plant up to 6 or 7 cm. high, 9-10 times dichotomous, cartilaginous, 

 dark red, cylindrical continuous, 1.5-3 mm. broad (dried) ; axis in- 

 visible, cystocarps irregularly aggregated ; — axis slender, adult cortex 

 83-90;a broad; outer cortex 50-70/a, commonly 50-60/x. broad, of 2-3 

 layers of large rounded hjpodermal cells and short anticlinal rows 

 alternating with single larger cells, the utricles; inner cortex 20-3(V 

 thick, of loosely interwoven corticating filaments ; monoecious ; 

 antheridia in groups, borne singly on elongated supporting cells ; cysto- 

 carps (young in fragments examined) of the Scinaia type with a 

 periderm pseudoparenchymatous below% but filamentous above. 



For some years the writer has looked upon a certain plant of the 

 Scinaia assemblage, more or less frequent on the coast of California 

 and differing in aspect from other members of the Scinaia group 

 especially in its abundant branching, darker color, and a certain 

 robustness, as probably the same as the Ginannia undulata ]\Iont., the 

 Scinaia furcellata var. undulata (Mont.) J. Ag. A superficial exami- 

 nation of the specimens in Herb. Montague at the Museum d'Histoire 

 Naturelle at Paris seemed to confirm this impression and antheridial 

 plants colected by C. P. Nott at Monterey, California, were distributed 

 under J. G. Agardh's combination (Phyc. Bor.-Amer., No. 422). 

 Recently, however, through the kindness of Dr. Paul Hariot, the 

 writer has been able to make a more thorough examination of the 

 Montague specimens, with the result that the previous impression has 

 been dissipated and the discovery made that the specimens upon w^hich 

 Montague founded his species belongs to the genus Gloiophloea rather 

 than to Scinaia and that the California specimens referred to do not 

 agree with them. Consequently Gloiophloea undulata (Mont.) is 

 proposed as a new combination to refer solely to the Chilian and 

 Peruvian species. 



From the literature, it seems that the specific name undulata 

 chosen by jMontagne for his Ginannia undulata was taken from a 

 manuscript name given to the species by some one else (cf. JMontagne, 

 1842, p. 257) and the original combination was probably the Haly- 

 menia undulata J. Ag. ]\Iss., quoted by Montague [loc. cit.), J. G. 

 Agardh (1851, p. 422), Kuetzing (1843, p. 393), and others. The 

 original specimen seems to be one collected by Bertero, but IMontagne 

 evidently founded his species on specimens collected by Gaudichaud 

 on the voyage of the ' ' Bonite. ' ' These specimens have been examined 

 and particularly one marked, apparently in Montague's handwriting, 

 "Ginannia undulata IMontag. in Gaudichaud Voy. Bonite c. icone 

 Chile." Besides this are two other specimens from Chili. All three.
