The foregoing list was furnished by the Department of the Interior 

 of the Insular Government, and comprises the mangrove lands and 

 marshes belonging to the People of Porto Rico, ami situated along Lie 

 north coast of the island, according to the data found in the archives of the 

 Department. Only the lands under No. 2 were added to this list by the 

 writer, they having passed into private ownership. 



All these marsh and swamp lands are located only a short distance 

 from the sea shore and separated from it usually by low sand bars or 

 coral reefs. Some of them are still, directly or indirectly, connected 

 with the sea, while others are completely isolated. In their natural state 

 they are either covered with water or the ground water is quite near 

 the surface. % 



The native vegetation of these marshes consists mainly of the 

 following plants, which Mr. J. R. Johnston, Pathologist of this Station 

 and Mr. W. E. Hess, of the Agricultural Experiment Station at Maya- 

 giiez, have identified. In the Caho de Tiburones there were found, 

 Melanthera aspera Compositae ; Andropogon sp. Gramineae ; Cono- 

 carpus erectus Combretaceae ; Lippia nodinora Verbenaceae ; Polygala 

 panniculata Polygalaceae : Hydrocotyle sp. Umbelliferae ; and one of 

 the Cyperaceae (Johnston.) In the vicinity of the Laguna de San Jose 

 the vegetation consisted of mangrove, polypodium and typical salt land 

 .edges and rushes, (Hess).
