PLANTS OF SOUTHERN NEW JERSEY. 75 



biliSj Bquisitacece, Pinus virginiana, Uniola laxa, Stipa avenacea, 

 ChainceHrium luteum, Pogonia divaricata (one record), Quercus 

 phellos, Castanca pumila, I^iquidambar styracifiua, Neluniba 

 lutea, Viola atlaniica, Azalea nudiflora, Salvia lyrafa. Also the 

 following", which were apparently wrongly attributed to New 

 Jersey : Aletris aurea and' Chondrophora. 



Mr. Roland Harper* gives as species confined to the New Jersey 

 Pine Barrens, or much commoner in New Jersey than in adjoin- 

 ing States, Dicromena colorata and Aletris aurea, of which we 

 have no definite records, and Briocatdon parkeri, a middle district 

 plant which does not occur in the Pine Barrens. Poly gala lutea, 

 Clethra alnifolia and Sabatia lanceolata are given in his list of 

 characteristic North Carolina Pine Barren plants, but omitted 

 from the New Jersey list, though it would be hard to find more 

 generally distributed species in the latter region. 



An analysis of the Pine Barren flora based upon the data pre- 

 sented beyond shows the following numerical results :
