 sign of awakening spring in the swamps of south Jersey, but they 

 often attain their full length and flexibility some time before the 

 pollen is actually liberated, and they may be said to be in bloom.

 catkins formed the previous summer. Fr. — September.

* This tree as well as Pijius virginiana and some other species occurs along 

 the river below the dam at Mays Landing, along with species character- 

 istic of the Coast Strip. These, however, have not been found on the coast 

 and are completely cut off by the Pine Barrens from their relatives in the 

 Middle district.
