The salt marshes at York, Maine and as far south as Cape Cod are covered 
by a vegetation which consists primarily, according to PENHALLOW ?) of Spar- 
tina stricta var. alterniflora which grows along the open channels, Spartna 
patens back of the taller species and usually in higher ground mingled with 
sea lavender Statice Limonium var. carolinianum, Salitornia and Solidago semper- 
virems. 
The sand hook which exists at the extreme point of Cape Cod is bordered by an extensive 
salt marsh. The typic marginal species is Salicornia ambigua and the characteristie grasses of 
the marsh are Spartina polystachya, S. patens associated with Juncus Greenii, J. canadensis, 
Seirpus pungens (= S. americanus), while the marsh partially converted by sand into a fresh- 
water marsh is covered by extensive patches of Vaccinium eg surrounded by Cyperus 
Grayi and Carex silicea. When such areas become fresh w wamps, there appear species of
