*Helianthemum Canadeiise (L.) Michx. Frost-weed. 



Very common and abundant throughout, especially in gravelly soil 

 on the borders of forests. 



*Viola. The Violets. 



Various members of this genus have found a use in medicine, and they 

 all apparently possess ipecac-like properties. About 25 species occur 

 in this State, the most of them in this vicinity. 



POLYGALA SENEGA L. SENEGA. 



The occurrence of this species as one of the rarest plants of the State, 

 formerly abundant, is an illustration of the possibility of exterminat- 

 ing a useful species when unaided nature is trusted with its perpetu- 

 ation. 



Poly gala, polygama Walt. 



Occasional in the north, frequent in the south and common along the 

 sandy coast. 



*SAPONAPJA OFFICINALIS L. SOAPROOT. 



Very common and abundant along roadsides. The roots obtained from 

 the plant here have a totally different appearance from those which 

 are imported. 



♦Hypericum perforatum L. St John's Wort. 

 Very common in fields and along roadsides. 



ALTHAEA OFFICINALIS L. MARSH MALLOW. 



It is doubtful if this plant occurs. It has been reported by only one 

 botanist, and it is probable that he mistook something else for it. 



*Tilia. Basswood. 



Two native species occur. Although these are not used medicinally, as 

 is the European species, it is altogether possible that they would serve 

 the same purpose. 



*LINUM USITATISSIMUM L. FLAX. 



This occurs frequently, and demonstrates its adaptability to cultivation 

 here. 



♦GERANIUM MACULATUM L. GERANIUM. 



One of the commonest and most abundant of our wild plants, and ad- 

 mirably adapted to collection for medicinal purposes. 



♦XANTHOXYLUM AMERICANUM MILL. PRICKLY ASH. 



Rather common, but not sufficiently abundant, except in a few locali- 

 ties, to be adapted to cultivation. 

 Ptclea trifoliata L. Wafer-Ash. 

 Occasional near the Delaware. 



*Ailanthus glandulosus Desf. Ailanthus. 



Very common along roadsides and in waste places. 



*Ilex verticillata (L.) A. Gray. Prinos or Black Ader. 

 Common and abundant in low grounds, throughout.
