This plant must be considered as an offshoot of Gerardia 

 purpurea L. (abundant through most of the Atlantic Coastal 

 Plain), adapted to, and largely replacing that species in the 

 peculiar environment of the Pine Barren region of New Jersey. 

 The two forms seem quite distinct, and for their better under- 

 standing a diagnostic comparison is given. The characterization 

 of G. purpurea L. represents the normal form of the plant as 

 occurring about Washington, D. C, on the lower Susquehanna 

 River in Pennsylvania, in Delaware, and in New Jersey. 



Stem rather stout, 4-9 dm. tall, usually sparingly scabrellous; 

 branches stifif, spreading; leaves linear or broadly linear, those 

 of the stem 3-5 cm. long, 1.5-3.5 mm. broad, not curhng on 

 drying; inflorescences not strongly racemose; calyx-lobes tri- 

 angular-lanceolate to triangular-subulate; corolla mostly 25-30 

 mm. long; capsule globose, mostly 6-7 mm. in diameter. 



G. purpurea L. 



Stem slender, 3-6 dm. tall, smooth; branches slender, elon- 

 gated, ascending; leaves narrowly linear to fili orm, those of the 

 stem 1.5-2.5 cm. long, 0.5-1.5 mm. broad, usually curling on 

 drying; inflorescences strongly racemose; calyx-lobes triangular- 

 subulate to subulate; corolla about 20 mm. long; capsule ellip- 

 soid-globose, 4-4.5 mm. in diameter G. racemulosa.
