Wet bogs of the Pine Barrens. 



This is a species which does not associate with the other white 

 Bonesets, unless it be with B. leiicolepis. It is strictly a Pine 

 Barren species frequenting the great natural bogs in the heart of 

 the region where grow Xyris congdoni, X. Unibriata, Briocaulon 

 decangulare, Gyrostachys prcECox, Helianthus angustifolius, Lo- 

 belia canbyi, etc., and is not known to occur outside of New 

 Jersey. 



At Manahawkin, where the Pine Barren swamps come well out 

 to the coast and the range of this species meets that of B. per-

 between the two.
