cate the fruiting seasons to be the same as in M. affine ciliare, with a period 
of eleven months from the maturity of the antheridia and archegonia and 
their contents in June, to the maturity of the sporophotes in the following 
May. This similarity of location, appearance and fruiting time between 
M. ajjine ciliare and M. Drummondii suggest the question of relationship 
between them, and if there is a relationship how close is it? 
The question will lend an added interest to the observations of the 
coming season.
