INTRODUCED GENERA AND SPECIES. 
1. HYDROCOTYLE L. Sp. Pl. 1: 284. 1753.—For description of genus and 
native species, see page 25, 
Hyprocoty.k BoNARIENSIS Lam. Eneyel. 8: 153. 1789. Although seeming well 
established in many places in the South, this species is generally considered as an 
introduction from South America. It is often reported from ballast heaps in the South. 
2. ERYNGIUM L. Sp. Pl. 1: 232. 1753.—For description of genus and native 
species, see page 42. 
Eryncium campestre L. Sp. Pl. 1: 233. 1753, a European species, was found on 
ballast grounds of Maryland, at Baltimore, by Katherine A. Taylor, and at Canton by 
B. Sollers, both in 1891, and again at Baltimore in 1898 by CLC. Plitt. 
EryNGium rortipum L, Sp. Pl 1: 232. 1753, a West Indian species, was reported 
by Michaux as having been found by him in dry fields in Florida, and was said by 
Pursh to occur in Georgia and Florida, but never having been found subsequently it 
should probably be excluded from the flora of the United States. 
ErynGium NAsturTIFOLIUM Juss. in Delar. Eryng. 46. pl. 17. 1808, a Mexican 
species, was found by G. (. Nealley at Santa Maria, Texas, in 1889, 
Eryneium pLaAnum L. Sp. Pl 1: 238. 1753, a European species, was collected in 
1899 by EH. S. Steele, growing spontaneously on a terrace along Massachusetts avenue, 
Washington, D. C. 
Eryngium prvaricatum H. & A. in Hook. Bot. Mise. 3: 350. 1833. From time 
to time for the last several years an Eryngiiun has been reported from the Southern 
States differing from any native species as well as from all material in the National
