As part of an international trial of provenances, three species of Eucalyptus (Myrtaceae) were tested in Puerto Rico on two sites, one a combination of Tanama clay and Coloso silty clay loam, the other a Mayo sandy loam. Both sites represent large reforestable areas in Puerto Rico. Five provenances each of E. deglupta Blume and E. urophylla Blake and two provenances of E. alba Reinw. ex Blume were outplanted in 1971. Five years after outplanting, mean heights averaged from 10.3 m to 17.9 m, with the tallest tree over 26 m. D.b.h. averaged from 9.2 cm to 16.8 cm, and survival ranged from 23 to 92 percent. E. deglupta and E. urophylla grew quite well on both sites, with variation due both to site and to provenance. E. alba growth was less impressive.
