always situated at the end of ordinary nemathecial fila 
ments or cortical cell-rows, and the absence of a well devel- 
oped nucleus make it highly improbable that they should 
be comparable with carpogones. 
The other kind of cells differ by their greater thickness 
and by richer contents. They arise at the upper end of 
the nemathecial filaments, terminal or lateral, singly or 
usually in small groups which seem to arise by division

of a single cell. They have the character of generative 
cells. Some of them, at least, grow out, in particular in 
a horizontal direction, between the nemathecial filaments, 
where their course may be rather irregular. The cells of 
these filaments are much larger than those of the nema- 
thecial filaments and they become poorer in contents and 
therefore often rather hyaline. Fig. 6 shows a horizontal 
filament running just within the cuticle, and fig. 7 the 
border of a nemathecium the outer portion of which is 
exclusively composed of large cells of the same origin. In
