PLANTS OF SOUTHERN NEW JERSEY. 573 



Named in honor of C. S. Rafinesque (1783-1840), an eccentric 

 naturalist, but to some extent fulfilling his own estimate that in 

 matters of classification and nomenclature he was far in advance 

 of the men of his time. Rafinesque was thoroughly acquainted 

 with the flora of the Pines and discovered not a few new species 

 among the swamps and bogs of this region.*
