the cedars, and several of Acer rubruin. The shrubby and her- 

 baceous vegetation consisted chiefly of the following species : 

 Viburnum dentatuin Unifoliuui canadotse 



Kalmia latifolia Arisaema tripliyllum 



Clcthra alnifolia Spathyema foetida 



Aralia iiudicaulis Carex folliculata 



PartJienocissus quinqtiefolia Lycopodiuvi lucididum 

 Ilicioides mucronata Woodwardia (^Lorinserid) arcolata 



Ilex verticillata (?) Dryopteris simidaia (?) 



Benzoin aestivale Osinunda spectabilis {regalis) 



Rhus Vernix Osinunda cinnaviomea 



RJuis radicans Sphagiiiiui sp. 



Rubus hispidus 



A little farther up the creek, near the railroad, were noticed 

 most of the same species, and in addition Trientalis americana, 

 Gaylussacia frondosa, and Asalea viscosa glauca. 



The Aralia seemed to be the most abundant dicotyledon in the 

 swamp. Lycopodiuvi luciduluin does not seem to have been pre- 

 viously reported from Long Island, though Dr.G.H. Shull tells me 

 that it is not uncommon in the vicinity of Cold Spring Harbor, on 

 the north shore. I was greatly surprised to find it in the coastal 

 plain (doubtless a new region for it), and so close to a salt marsh. 



Chamaecyparis thyoides is one of the very few conifers (and the 

 only water-loving one) indigenous to both the glaciated region 

 and coastal plain, and the only one now confined to these two 

 regions.* (Not much is known of its prehistoric distribution, 

 for in the fossil state it is reported only from the Pleistocene of 

 New Jersey, and the buried trunks found in the coastal plain far- 

 ther south are mostly in places where it still grows.) Its rela- 

 tions to the topography in the two different regions are rather 

 interesting. In the glaciated region I have seen it only in " ket- 

 tle-holes," or " undrained swamps," while in the coastal plain it 

 seems to be confined to "drained" but non-alluvial swamps. 

 Its very irregular distribution in the coastal plain has been re- 

 cently commented upon.f
