ADDITiaNAL OBSERVATIONS ON THE STR4.ND FLORil OF NEW JERSEY. 

 BY JOHN W. HARSHBERGER, PH.D. 



The writer presented at some length in the Proceedings for 1900 

 (pp. 623-671) an " Ecological Study of the New Jersey Strand 

 Flora " The supplementary study which is given here represents 

 the materia] collected iu a field study since the publication of the 

 aforementioned brochure. The notes are arranged under several 

 subheads, but, when taken together, they throw additional light 

 upon a region of eoologic interest. 



The Strand at Holly Beach. 



Holly Beach, situated one mile beyond Wild wood, was visited a 

 second time in August, 1901, for a more extended survey. The 

 beach along the sea front is flat, as at Wild wood, without a sea- 

 dune. The driftwood area in 1901 was very extensive. The tree 

 formation, which is dense at Wild wood, gradually decreases in 

 extent until it disappears at the edge of an extensive salt meadow. 

 Along the edge of the grass-covered meadows, the grass of which 

 was being cut for hay, were found an abundance of the rose mal- 

 low, Hibiscus moscheutos L., Kosteletzkija virginica Gray, Cassia 

 chamoicrista L. and A--clepias incarnata L. Cephalanthus oeciden- 

 taliji L. was noticed in the thicket growth. The meadow was 

 sufficiently high in many places to enable the farmer to cultivate 

 Indian corn, which grew normally in such unusual surroundings. 



Forest at Wildwood. 



The trees of this forest seem to have reached maturity and 

 are on the decline. This is without doubt due to the removal of 

 the undergrowth from about the trunks of the dominant trees. 

 The soil dries out more quickly under such altered conditions, 

 the wind has better chance to reach the trees and to circulate 

 about them, producing an increased transpiration which proves 

 deadly to the maturer arborescent species that had established a 

 balance between the absorption of water by the roots and the
