ADDITIONS TO THE TREE FLORA OF THE 

 UNITED STATES 



By J. K. Small 



In a previous paper * I recorded the discovery of six trees new 

 to the flora of the United States. Four of the species there men- 

 tioned, namely Qacrcus Rolfsii, Small, Ilex Kriigiana Loesener, 

 Rlius leiicantJia Jacq., and Tetrazygia bicolor (Mill.) Cogn., are 

 indigenous to Florida, while two species, Mangifera indica L., 

 and Sapota Zapotilla (Jacq.) Coville {Achras Sapota L.) are 

 naturalized plants. 



Further exploration in South Florida has revealed six addi-

 Carolina, Georgia, and northern Florida, the stem never rises 

 above the surface of the ground. In South Florida, under quite 

 similar conditions, the stem not uncommonly stands erect or
