of these grow wild also in one or more Common- 

 wealth Forests. Though local on this island, 

 many occur in sufficient numbers that they are 

 not rare. Two are also in Vieques, and 1 also has 

 been found in St. Croix. 



Two additional endemic species have been 

 planted in the Caribbean National Forest: 151. 

 Montezuma speciosissima Sesse & Moc, maga. 

 389. Sabinea florida (Vahl) DC, retama, watta- 

 pania. 



The number of endemic species has been re- 

 duced slightly by reduction to synonymy under 

 widely ranging species. Also, a few former en- 

 demics have been found on other islands.

3. Trees Rare in Puerto Rico but Native Beyond 



This list contains 22 tree species of the Carib- 

 bean National Forest classed as rare in Puerto 

 Rico but native also in other islands beyond, or 

 rare nonendemic species. These border or pe- 

 ripheral species found nowhere else in the 

 United States merit protection here, though not 

 in danger of extinction.
