M elicope ( R utaceae) is one of the largest plant genera on the H awaiian I slands. We present here a detailed molecular phylogenetic analysis of the H awaiian species of this genus and compare the results with the other genera of H awaiian R utaceae, P latydesma and Z anthoxylum . Four nuclear and two plastid markers were sequenced, with the goals of untangling phylogenetic relationships, inferring biogeographic events and comparing patterns of distribution among the three genera. Our results show that there were two colonization events ( M elicope + P latydesma , and Z anthoxylum ) to the H awaiian I slands, that H awaiian R utaceae have an A sian, A ustralian or P acific origin and that there were two independent colonization events of H awaiian M elicope lineages to the M arquesas Islands. The two most widely distributed H awaiian M elicope spp. are not monophyletic and the current subgeneric classification of H awaiian M elicope is highly artificial. On the H awaiian I slands, M elicope and Z anthoxylum show contrasting biogeographic patterns, suggesting different patterns of dispersal. M elicope has a high percentage of single‐island endemics suggesting low dispersal ability, whereas Z anthoxylum taxa tend to occur across multiple islands. © 2013 The Linnean Society of London, Botanical Journal of the Linnean Society , 2014, 174 , 425–448.
