Comm'on in sand in the Pine Barrens and occasional in sandy 

 spots of the Middle district including its extension north of 

 our l)oundary 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, W'hich appear before the foliage, and later 

 its rosettes of somewhat fleshy lea\'es. will be found to spring 

 from a cluster of slender stemfe, 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 5.5 x 3 cm. with 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 l)y side in perfectly 

 uniform surroundings. 



Fl. — Late April to late May. Fr. — Late May to late June.
