Common in sand in the Pine Barrens and occasional in sandy 

 spots of the Middle district including its extension north of 

 our boundary and in the Cape May peninsula. 



This is another of the characteristic plants of the Pine Barrens, 

 delighting in the most arid stretches of white sand. Its tufts 

 of yellow blossoms, which appear before the foliage, and later 

 its rosettes of somewhat fleshy leaves, will be found to spring 

 from a cluster of slender stemte, which unite as we dig down- 

 ward until they finally coalesce into one stout root. How far 

 it descends I have never been able to ascertain, though I have 

 followed several for three feet into the sand, at which point they 

 showed no sign of diminishing in thickness. Both leaves and 

 stems are full of the milky juice characteristic of the genus. 

 The leaves vary greatly in both size and color, some are linear 

 and others broadly oval 5.5x3 cm. w'ith all possible intermediates, 

 while all styles occur either green or deep crimson. The varia- 

 tions are not correllated with any conditions of environment, so 

 far as one can see, extremes growing side by side in perfectly 

 uniform surroundings.
