were really carpogonia. Such dubious cases 
are shown in fig. 105 C, D; I have been in- 
clined to interpret them as carpogonia, since 
they had the same refringent and colourless 
contents as the others. In some cases the 
supporting cell in the vertical filament had 
a similar appearance (fig. 105 C, D) (Comp. 
Petrocelis Hennedyi, p. 178). The undermost 
cell in the carpogonial filament is sometimes 
connate in its whole length with the suppor- 
ting filament. Sporogenous filaments were 
not seen in connection with the carpogonium, 
but they were found fusing with the auxili- 
ary cells. These cells are intercalary in the 
vertical filaments and differ but little from

presumed carpogonium sitting directly on the ver-

the other cells, possibly sometimes swollen before fusion. The sporogenous filaments 
run principally in a horizontal direction, but sometimes give off upward branchlets,
