ONE OF 
4. Orchid seedlings, both native and cultivated, show the fungus 
present in their cells from the éarliest stages of development. We know 
that in certain cultivated Orchids, at least, the fungus enters the cells of 
the seeds (in culture flasks), before any development can be made out. 
The fungus does not grow more or less in a straight line as is almost 
universal in the group, but rolls itself up in one cell before passing on to 
the next. Further, the fungus in such cases as Odontoglossum, Vanda, 
étc., degenerates and does not pass into the developing root.
