shore at Stevns (C. H. Ostenfeld); SD, N.E. of Moens Klint, 23.5 m, sand, loose, though several spec 
with attachment disc; QZ off Moens Klint, 7.5 m, abundantly, loose, some with attachment disc. Similar 
specimens collected by Liebman at Moen, undoubtedly on the shore, are to be found in the herbarium 
of the Botan. Museum of Copenhagen.

As to the nomenclature of the species, reference may be made to the explana- 
nation by HAUPTFLEISCH (1912, p. 308). 
The structure of the frond has been treated by several authors (NAGELI, 
BERTHOLD, WILLE, DEBRAY, HAUPTFLEISCH, HASSENKAMP, Kyrın). The reader is referred 
principally to the papers of HASSENKAMP and 
Kyrın quoted above; here only the most important 
facts will be adduced. The frond is tubular, articul- 
ated with diaphragms at the constrictions. The wall 
of the frond is composed of one layer of large 
cortical cells, from the outer edges of which 
smaller cells are cut off by oblique walls. These 
small cells do not form a continuous layer but 
form a reticulate system of outer cortical cells. 
The large, primary cortical cells are at first 
angular, nearly isodiametrical, when seen from 
the face; later they increase considerably in the 
direction of the longitudinal axis of the frond. — 
There is not one apical cell at the tip of the 
frond, as indicated by NÄGeErı and WILLE, but a 
number of cell-rows meet at the apex, each with 
an apical cell dividing by transverse walls. Within 
the cortex run a number of about 16 to 20 
longitudinal, narrow cell-rows, and at regular 
intervals the cavity of the frond is traversed by
