RANDELL AND CLIFFORD W. MORDEN ,3 ABSTRACT: The Hawaiian Plant DNA Library of endemic and indigenous plant species preserves genetic material from all Hawaiian Islands. DNA acces sion numbers are reported here for 155 native species representing 92 genera and 48 families. Federal status of endangered species is indicated where appli cable. Accessions for 71 species in 52 genera and 10 families of introduced spe cies are also reported. Pest and invasive species are also indicated. OVER 86% OF HAWAIIAN vascular plant spe genetic research (Morden et al. 1996). We cies are endemic (Wagner 1991). This as report an additional 883 accessions of native tounding array of endemism is unfortunately species, with 127 endemic and 28 indigenous coupled with an alarming rate of endanger species, in 92 genera and 48 families.
