wall (fig. 25). As the cell gradually expands, the nucleus also 
increases in size. The nucleus just before synapsis has already 
aquired nearly its full size, and the linin network composed of 
very slender threads is plainly visible. In it are irregularly 
distributed a few large and small granules of chromatin. Both 
the linin and the granules are exceedingly meager as compared 
with Convallaria. The nucleolus is a gigantic body, much larger 
than those in most plants, and takes the gentian-violet stain 
readily, making it thus a very striking object in the cell. 
Attached to it on one side is a small wart-like body only slightly 
lager than the largest chromatin granules. Rarely two of these
