ABSTRACT
In 1942 two scale insects were accidentally introduced into
Bermuda with devastating effects on Juniperus bermudiana, endemic
to Bermuda. In an effort to repopulate junipers on Bermuda, two
cultivated junipers from Florida were introduced by J. D. C. Darrell in
1940s (Darrell's cedar) and Reeve Smith in the 1950s (Smith's cedar).
Analysis of SNPs of nrDNA and trnC-trnD cp DNA determined that
Darrell's cedar is Juniperus virginiana var. silicicola and Smith's cedar
is Juniperus v. var. virginiana. SNPs analysis reveal what appears to
be F1 hybrids between Darrell's cedar (J. v. var. silicicola) and J.
bermudiana. In addition, two individuals were found that contained
nucleotides from Darrell's cedar, Smith's cedar and J. bermudiana,
