SPECIAL LISTS 



Common tree species of Puerto Eico and the 

 Virgin Islands with some distinctive character, 

 special feature, or use in common have been 

 grouped together in various lists. These lists may 

 be helpful in identification, in locating trees with 

 useful products, and in selecting species for plant- 

 ing. Only those trees outstanding for a particular 

 character or use are included. To save space the 

 tree species are cited by their numbers, and com- 

 mon and scientific names may be found under
