Summary. This group is somewhat intermediate between the 

 sand-hill bogs and the ordinary alluvial creek-swamps already 

 discussed, but differs from both, and probably from all other 

 habitat -groups in the region, in the larger proportion of ever- 

 greens, and of bryophytes. There is the greatest possible contrast 

 between these swamps and the sand-hills near by, in almost 

 every respect. Particularly is this true in winter, when nearly 

 all vegetation on the sand-hills looks dead, while that in the non- 

 alluvial swamps looks about the same as in summer. 1 There are 

 no species common to the two places, and not many families even. 



In these swamps all the trees and most of the shrubs are ever- 

 green. The few and relatively inconspicuous herbs are all 

 perennial, and all either monocotyledons or cryptogams. Flowers
