'To anyone unacquainted with the wild parts of Kew Gardens it 
may seem incautious to consider as indigenous any of the mosses 
now found growing within these limits. But it is only with 
and 
to them, that a probability of introduction exists. In many 
places in the Gardens, ¢.g., the boundary ditch and bank running 
. the length of the Old Deer Park, the Queen's Cottage Grounds, 
parts of the Palace grounds, etc. „ the nature of the surface 
makes it quite safe to consider the species growing there as 
indigenous. The inclusion of the river-bank in the area has 
led to Mie ‘addition of several interesting aquatic mosses, and, 
without doubt, = these are quite wild.
