This curious distribution, which is shared by Geranium

Polygonatum commutatum'' Britton 240. 



Polygonatum biflorum Knieskern 32. — Willis 65 (in part). — Britton 240 (in 

 part). 



In woods of the Northern, Middle and Coast districts rather 

 common; rare and perhaps recently introduced in the Pine 

 Barrens. 



In spite of the general statements in the catalogues of Britton 

 and Keller and Brown, I can find no authentic specimens of P. 

 hiflonmi from our region. The present plant is extremely vari- 

 able in size, width of leaves and number of flowers, and would 

 lead one to suppose that more than one species were represented, 

 but it is impossible to find any constant differences between them 

 and none are referable to S. biflora of the northern counties.
