Rather frequent in lakes and ponds of the northern counties 

 and in ponds and dammed streams in the Pine Barrens and Cape 

 May district ; apparently rare in the Middle district. 



A very characteristic species of the old milldams in the Pine 

 Barrens, though its smaller peltate leaves and little maroon 

 colored flowers are not nearly so conspicuous as the showy 

 blooms and large leaves of the true Water Lilies. The petioles 

 and buds are encased in a thick coating of jelly-like mucilage. 



PI. — Early June to early August. Fr. — Early July to early 

 September, probably.
