PLANTS OF SOUTHERN NEW JERSEY. 349 



This curious distribution, which is shared by Geranium 

 robertianum and some other species, is discussed at p. 105, 

 F/.— Early May to late May. 



Middle District.— Vrtehold (C). 



Coast Strip.— Sandy Hook, Sea Bright (NB), Barnegat City (L), Cedar 

 Bonnet (L), Beach Haven Terrace (L), Ocean City (S), Wildwood, Peer- 

 mont, Cold Spring, Cape May Pt. (KB), Sea Breeze, Salem Co. (P). 



POLYGONATUM Hill. 

 Polygonatum commutatum (R. & S.). Smooth Solomon's Seal. 



Convallaria commutata Roemer and Schultes Syst. 7. 1671. 1830 [Pennsyl- 

 vania]. 



Polygonatum gigaoiteiim Knieskern 32. — Willis 65. 



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. 

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

 able in size, w^idth 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. hiiiora of the northern counties.
