Common in wet sand throughout the Pine Barrens, and rarely 

 in outlying pine barren islands in West Jersey and on the coast. 



This is a far handsomer species than either of the preceding, 

 and from the nature of its growth far more conspicuous. The 

 large crimson-pink flowers are open only during part of the 

 morning on sunshiny days, closing up at other times like the 

 Portulaca of our gardens. The plants prefer open damp sand, 

 where they are not shaded or crowded by other vegetation. 

 Sometimes they grow very abundantly in such spots, and I have 

 seen their erect filiform leaves in rank upon rank, the glutinous 

 secretion on the glands glistening in the sunlight and making the 

 whole patch look like dew covered spider webs, such as we fre- 

 quently see on an early autumn morning. When examined 

 closely the leaves will always be found to have small flies, mos- 

 quitoes and other insects attached to their thread-like glands.
