ECONOMIC VALUE OF THE BRYOPHYTES 
Although the majority of the Bryophytes are of small size 
when compared with the seed-bearing plants, they often form 
dense-and extensive colonies. and thus constitute a conspicuous 
feature of the landscape. This is especially true in mountain- 
ous and northern regions, where woody plants are stunted in 
growth and occur more sparingly than under more favorable 
climatic conditions. Even in Connecticut, however, where the 
higher plants exhibit a vigorous development, the Sphagnales 
and certain of the other Bryophytes are often abundant enough 
to attract the attention of the ordinary observer. 
On account of the tufted habit of so many species and the 
power which they possess of absorbing and retaining water,
