TaBLE XXXVIT. (see § 23). 
Number of leaves of the fertile stem. 
In this table a rather great possible error is to be admitted. The figures 
indicate the number of leaves which still remain in a stem which bears a ripe 
or almost ripe fruit. In such stems the lowest leaves have almost always 
disappeared. (See $ 23.)

Tastre XXXVIII. (see $37). 
Number of fruits at the summit of the fertile stem (see § 37). 
In several species this property is very variable. The figures in this table 
are to be considered as a rather incomplete information. Besides the fully- 
developed fruits, abortive fruits (length 2 mm. or longer) which are easily 
distinguished from sterile archegonia are sometimes found; such abortive 
fruits have always been counted and brought into account. In all the 
species, stems with one fruit will likely be found. Fruits which sometimes 
occur at the summit of lateral branches (Mn undulatum and perhaps other 
species) are not taken into account.
