Occasional in the western part of the State. 



*APOCYNUM. DOGBANE. 



There is scarcely any other plant of the Pharmacopoeia which is so 

 much in need of study as this. Upon the one hand, we have abundant 

 evidence that some preparations of the drug exert an important cardiant 

 action, while others are inert, and, upon the other, the certainty that 

 a number of species have been badly confounded. It has long been ac- 

 cepted that wia had but two species, A. Cannabinum L. and A. Andro- 

 saemifolium L., the former presenting a number of varieties. Recently 

 Prof. Greene has described A Medium and A. Album as segregations 

 from A. Cannabinum. It is very likely that both of these species are 

 common hereabout, but time has not been allowed for determining 

 their distribution in the State. 



*ASCLEPIAS TUBEEOSA L. PLEURISY ROOT. 



This is another plant calling for close, study. That the A. Decumbens 

 L., which has recently been reinstated, is really a good species, I do not 

 feel at all sure. The plant is common enough throughout the State, 

 preferring sandy soil. 

 A. Syriaca L. and A. Incarnata are also very common and similarly used. 



Sabbatia. American Centaury. 



Five species of these plants occur in the State, mostly near the coast, 

 and all possess properties similar to the Gentians. 



* Gentian a. Gentian. 



Seven Gentians occur in the State, G. Andrewsii and G. Saponaria being 

 rather abundant and more or less used, like the official species. 



♦Menyanth.es trifoliata L. Bog-bean. 



Occurs in swamps in quite a number of localities. 



SYMPHYTUM OFFICINALE L. COMFREY. 



Occurs rather commonly in waste places as an escape. 



Ipomoea pandurata (L.) Meyer. Man Root. 



Common in the sandy soil of the southern districts, and occasionally 

 northward. 



Solan inn nigrum L. Nightshade. 



Solanum Carolinense L. Horse Nettle. 



Both occur frequently as introduced plants. 



*SOLANUM DULCAMARA L. BITTERSWEET. 



Very common along streams and about the borders of ponds. 



♦DATURA. STRAMONIUM. L. STRAMONIUM. 



Very abundant in all waste places. The plant is so readily collected, 

 and the certainty of a good article is so important, that it would be 

 well if it were oftener collected here. The frequency of serious cases 

 of poisoning by it makes it important that it be known by every one.
