Tables XIII, XIV, and XV take the same data as presented in 
previous tables but the results are given by number of species 
rather than by average numbers. The number of species in each 
group which performed certain things under certain conditions 
are given without respect to the name of the species. This is 
perhaps a better way of drawing conclusions than to use average 
figures. Each species is counted in its proper column; if a 
species, for example, germinated simultaneously in two cultures 
it counted one half in each column.

Out of 34 species 31 germinated first in either of the two 
shade cultures and only 3 began their germination in the open 
light. The tendency to germinate first in the shade is more 
marked in the case of the xerophilous and the mesophilous species 
and less marked in the xero-mesophilous. Out of 27 species,
