ones which have the power of germination. Each spore consists of | 
two cells, both of which are furnished on either side just above the 
point of juncture with a single pore through which the germinating 
thread protrudes exactly after the fashion of pollen tubes. Occa- 
sionally all the four pores are fertile, but more frequently one or two 
only protrude the cotyledonoid. The pores of the two cells, it should 
be observed, correspond exactly in position. In no case have more 
than two been observed in each hemispore.—M../. B.—Gard. Chron.
