Back-tracking New Jersey Plants 



John A. Small 



On a field trip last fall (September 30, 1939) under the guid- 

 ance of Dr. Meredith Johnson, New Jersey State Geologist, a 

 search was made for fossil plants in the limonitic sandstone of the 

 Pensauken formation in East Brunswick Township. This locality, 

 the only one reported of its kind, was discovered by Dr. Alfred 

 Hawkins some ten years ago. It is a very small area. A good 

 number of imprints were found but they showed only fragments 

 of leaves. The original collection had removed the best of the 

 exposed material. None of us were sufficiently trained paleo- 

 botanists to name the species foiuid. The earlier collections were 

 studied by Dr. Edward W. Berry and published with Dr. Hawkins 

 as "Flora of the Pensauken Formation in New Jersey" in the 

 Bulletin of the Geological Society of America, vol. 46, 1935. Eleven 

 species were reported : Onoclca scnsihilis, Salix Iniiiiilis, Castanca
