Sauvageau, to whom I sent some preparations, writes to me: »C’est 
un Chilionema nov. spec., mais vos preparations sont insuffisantes«. 
Later on I have tried to examine the plant more closely, but have 
only partially succeeded in doing so owing to the material being 
apparently rather undeveloped. In fig. 82 I have shown some frag¬ 
ments of the plant. The basal disc has a distinctly marginal growth 
(fig. 82, f and g) and consists of closely united, branching filaments. 
The greater part of the disc is composed of two layers of cells 
owing to the cells dividing in a direction parallel to the surface 
of the disc; only here and there a few undivided cells occur. The 
cells are about 10 fi broad. 
As is characteristic of the genus Chilionema (cfr. Sauvageau, 
Myrionemacees, p. 103), the erect filaments and sporangia occur in 
scattered groups on the surface of the basal disc, surrounded by
