ABSTRACT
Five Hesperocyparis (Cupressus) abramsiana groves were
analyzed by Inter-Simple Sequence Repeats (ISSRs). ISSRs analyses
revealed geographical differentiation among the groves (= Silba's
subspecies) with the Butano Ridge grove being the most distinct in
both ISSRs and terpenoids. Combined ISSR and terpenoid data
support the recognition of Hesperocyparis. abramsiana var.
abramsiana and Hesperocyparis abramsiana var. butanoensis Bartel
& R. P. Adams, comb. nov. The recognition of Silba's subsp.
