The meeting was held at the College of Pharmacy ; Rev. J. 

 Henry Watson in the chair ; nine presons present. 



The paper of the evening was presented by Rev. L. H. Light- 

 hipe. It was entitled " The Flora of the Pine-Barrens of New 

 Jersey," and was illustrated by a large number of specimens. 



The subject was introduced by a sketch of the pine-barren 

 region which extends along the Atlantic coast immediately be- 

 hind the coastal zone and is limited at the northwest by the 

 Triassic formation, thus covering the Cretaceous and later geo- 

 logical formations. 



The plants most characteristic of the region of pine-barrens 

 were enumerated with reference to their general as well as local 

 distribution. The ferns most common are : Pteridium aqirihnnm, 

 Woodwardia Virginica, IV. areolata and Onoclea sensibilis. Schi- 

 zaea pnsilla has been found only in New Jersey, Nova Scotia and 

 Newfoundland. Lygodinm palmatum is found in New Jersey 

 only in a few places. Lycopodiaceae and Equisetaceae are com- 

 mon members of the flora. 



Pinus rigida and Pinus Virginiana are common, while Pinus 

 ecliinata is less often met with. In the swamps the white cedar, 

 Chamaecyparis thyoides, is characteristic.
