130 RHODYMENIACEAE 
traversed by a few filaments 3-6 и in diameter, their cells mostly 
20-100 и long, with granular contents or subvacuous, the fila- 
ments passing distally into the pyriform, fusiform, clavate, or 
ellipsoid cells of the subcortex, these cells mostly 15-504 X 
11—19 и, lying rather loosely in one or two strata, with their long 
axes parallel to the surface and with dense granular contents; 
cortex firm, I or 2 cells thick, the superficial cells 11-20 и hig. 
(including 3-4 и of surface jelly), 1-2 times as high as broad, 
their protoplasts in surface view angular or angular-orbicular, 
5-13 и in maximum diameter, separated by hyaline intervals 
2—5 broad; tetrasporangia sparingly scattered, 14-27 и X 
14-17 и, the spores “cruciate,” or irregularly paired. [PLATE 53;

The present species apparently belongs in the Cryptarachne 
section of Chrysymenia, standing nearest to the Floridian C. plani- 
frons (Melv.) J. Ag. and C. Curtissiana J. Ag. in general habit, 
but in structure more like the New Zealand Chrysymenia (2) 
apiculifera J. Ag. In the small size of the subcortical cells and 
in their dense granular protoplasts, it departs rather widely from 
these Floridian species and from C. ventricosa (Lamour.) J. Ag+ 
the Mediterranean and Adriatic type of the genus, yet is, in these 
respects, not far from С. (2) apiculifera. It differs, however, 
from the New Zealand plant very decidedly in its much larger 
size, the thinner less dissected thal- 
lus, with fewer, longer, and broader 
lobes, the absence of processes from 
the disc, etc. The thallus of Chry- 
symenia (?) lobata is not remarkably 
lubricous, but it is very thin and soft 
and adheres firmly to paper when 
dried under pressure. Іп its tenuity 
Neronis „о M the plant is, in fact, quite Porphyra- 
бай ый и ашы е like. In its thin gelatinous thallus t 
suggests also certain Pacific North 
American plants that have been referred by American phycolo- 
gists to the genus Aeodes J. Ag. but its structure is different from 
that of J. Agardh’s New Zealand type of this genus.
