%X &#8216;Eric John&#8217; is a novel variant and spontaneous hybrid that demonstrates the floral characteristics of two myrtaceous genera, Verticordia and Chamelaucium. A comparison was made between the essential oil profiles and morphological characters of &#8216;Eric John&#8217;, Chamelaucium ciliatum, C. floriferum, C. uncinatum, and Verticordia plumosa from the site of origin of &#8216;Eric John&#8217; to identify the parentage of the novel variant and assess the potential for intergeneric crosses. Biochemically, &#8216;Eric John&#8217; was strongly aligned with C. floriferum, while, morphologically, &#8216;Eric John&#8217; was closely associated with V. plumosa. These data distinguished &#8216;Eric John&#8217; as a possible C. floriferum V. plumosa hybrid and indicate the potential for development of novel gene combinations for horticulture. Large dissimilarities between the essential-oil profiles and morphometry of &#8216;Eric John&#8217;, C. ciliatum and C. uncinatum negated these latter species as parental stock.
