Aside from relatively steep, springy slopes, swamps of the 

 well-drained type are commonly developed alo'ng streams, in 

 places where the ground is subject to occasional inundation (see 

 further under head: formation-types along streams, p. 456). 

 The vegetation in swamps of the well-drained type is apt to 

 include more or less admixture of bog species, as shown by 

 the above list, but these occupy a subordinate position and 

 sometimes even the omnipresent ericad, Chamaedaphne, is 

 absent. The only occurrence of Typha latifolia noted on the 

 plateau was in a swamp of this description. Well-drained 

 swamps are far less frequent in the barrens than in the forested 

 region, but even here they are by no means absent, particularly 

 along the larger streams. 



b. THE ASSOCIATION-COMPLEXES OF POORLY DRAINED SWAMPS 



Under this head, here as in the lowland, may be included a 

 large number of swampy areas which, in the character and 

 ecological relations of their vegetation, appear to be intermediate 

 between the well-drained and the undrained types. There is one 

 group of swamps in particular which seems to fit in under this
