Taxonomic notes

Leaf terpenoid data indicate that, as with the other Caribbean junipers (J. barbadensis, J. bermudiana, and J. saxicola), this species is closely related to J. virginiana, an extremely widely distributed species of the eastern U.S. The species complex may be derived from an Appalachian ancestor (Adams 1995). There are three described varieties:

J. gracilior var. gracilior.

J. gracilior var. ekmanii (Florin) R.P. Adams 1995. Syn: J. ekmanii Florin 1934 (Farjon 1998).

J. gracilior var. urbaniana (Pilg. et Ekman) R.P. Adams 1995. Syn.: J. urbaniana Pilg. et Ekman 1926, J. barbadensis var. urbaniana (Pilg. et Ekman) Silba 1984, J. barbadensis subsp. urbaniana (Pilg. et Ekman) Borhidi 1992 (Farjon 1998).
