PINUS CARIBAEA: AN EXTENSION OF RANGE IN 



LOUISIANA 



By Wilbur R. Mattoon 



Louisiana, west of the Pearl River watershed, has never been 

 included within the range of Pinus caribaea Morelet, by any 

 authority so far as has come to the attentio-n of the writer. The 

 western range of the species, as given by Sargent, is "along the 

 Gulf coast to the valley of the Pear River, Louisiana."* 



During a southern trip in the spring of 1916, the writer had 

 occasion to observe closely Pinus caribaea from its northeastern 

 limit near Charleston, S. C., westward across the coastal plain 

 into Mississippi and Louisiana. At Slidell, St. Tammany Parish, 

 west of the Pearl River basin in Louisiana, reproduction from 

 scattering seed trees left in logging occurs over the flatland and 

 about vacant lots and yards in town. The resulting local land- 

 scape effect is most pleasing and leaves no doubt as to the opinion 

 that slash pine is "by far the most handsome of all southern 

 pines. "t The numerous outlying ponds contain cull trees about 

 their margins and heavy stands of young slash within and gener- 

 ally for some distance around the ponds. The soil here is the 

 low flatland type consisting of sand overlying clay. A striking 

 advance of slash pine over ponds and flat swamps, formerly 

 occupied by cypress and some of the so-called hardwoods, has 

 taken place extensively in the south due to the removal by 

 logging of the former continuous and protective virgin forest 

 cover. North of Slidell, pure stands of mature slash pine cover 

 mile after mile along the New Orleans Great Northern Railroad
