which the specimens recorded in Willis' list came, nor do I know 

 the name of their discoverer. 



In July, 1902, however, on an excursion of the Philadelphia 

 Botanical Club, Messrs. Van Pelt, Brown and Jahn rediscovered 

 this interesting plant at Point Pleasant, on the south side of the 

 Manasquan, and this colony is still flourishing. 



PL — Probably late spring to autumn. Fr. — ^Early July into 

 autumn, often persisting for a full season. 



Maritime. — Pt. Pleasant.

This curious little northern bog plant is one of those species 

 that, probably forced southward during glacial times, has man- 

 aged to persist locally in cold bogs far south of its normal range. 

 It occurs in various parts of the Pennsylvania AUeghanies and 

 in the New Jersey mountains at Budd's Lake. In the southern 

 part of the State it was known as early as 1818 to Barton and 

 Nuttall, the former of whom recorded it as rare in Cranben-y 

 Swamps of Jersey not far from Philadelphia. Whether the two 

 definite localities of which we have record were those known to 

 the older botanists or not I cannot say. It is certainly of very 

 rare occurrence in our region to-day, if not actually extinct. I 

 have personally never collected it in New Jersey.

Family ALISMACE^. Arrow-heads, Etc. 



Arrow-heads of one species or another are found along the 

 shores of nearly all the streams or ponds in southern New 

 Jersey. The Long-beaked Arrow-head is the species of the Pine 

 Barrens and Cape May, while the Common Arrow-head takes 

 its place in the Middle district ; the others are less frequent and
