“…The genus is distributed in temperate and montane-tropical regions from Borneo southeast to Australia, New Zealand, and associated subantarctic islands, and across the Pacific Ocean to Hawai'i and Juan Fernandez Islands. The centre of diversity for the genus lies within New Zealand (Oliver, 1935;Heads, 1996), where there are c. 50-55 taxa formally recognised (Eagle, 2006;Dawson, 2000;Norton & de Lange, 2003;Jane, 2005) and at least a further seven entities awaiting formal recognition (Eagle, 2006; P.J. de Lange, unpubl.…”

Coprosma solandri, an enigmatic species known only from the type collection, was described in 1897 by New Zealand botanist Thomas Kirk, based on material included in a duplicate set of Banks & Solander specimens, sent at Kirk's request, by the Natural History Museum (BM) in London to the Colonial Museum in Wellington in 1895. Here we revisit Coprosma solandri concluding that the specimens on which that name was based were not collected in New Zealand. We conclude the type of Coprosma solandri was derived from Hawaiian material of C. ernodeoides A.Gray that was accidentally sent to New Zealand on the assumption that Banks & Solander had collected it from there. Although available evidence precludes definite linkage to a specific collector, we raise the possibility that the original material derives from an Archibald Menzies collection made in 1793 in Hawai'i. The recognition that Coprosma solandri and C. ernodeoides are conspecific finally removes a puzzling Coprosma from the New Zealand flora 122 years after it was described and accepted uncritically as an endemic to that country.

A new endemic addition to Coprosma Sect. Acerosae, Coprosma elatirioides, is described from New Zealand. The new species is a common shrub of mid to oligotrophic wetland habitats along the West Coast and in the southern third of the South Island, and on Stewart Island. Previously, Coprosma elatirioides was included within a broad circumscription of C. brunnea, from which it is distinguished by its non-flexuous branching habit, comparatively large, conspicuous and persistent calyces and a deeply divided corolla on female flowers, and restriction to wetland habitats. Coprosma elatirioides is most similar to C. intertexta, from which it is distinguished by its subscandent, trailing growth form, shortly sheathing and conspicuously denticulate stipules, fleshy coriaceous, adaxially pubescent leaves with obtuse apices, and ecology. C. elatirioides is further distinguished from C. brunnea, C. intertexta, and the other coprosma species of Sect. Acerosae by nrDNA internal transcribed spacer (ITS) and external transcribed spacer (ETS) sequence differences.

Coprosma is perhaps the most ubiquitous plant genus in New Zealand. It belongs to the tribe Anthospermeae, which is distinctive in the family Rubiaceae through its small, simple, wind-pollinated flowers and its southern hemisphere distribution. The tribe comprises four main clades found respectively in South Africa, Africa, Australia and the Pacific. The high level of allopatry among the four subtribes is attributed here to their origin by vicariance. The Pacific clade, subtribe Coprosminae, is widespread around the margins of the South Pacific and also occurs on most of the high islands. Distributions of the main clades in the subtribe are mapped here and are shown to be repeated in other groups. The distribution patterns also coincide with features of regional geology. Large-scale volcanism has persisted in the central Pacific region since at least the Jurassic. At that time, the oldest of the Pacific large igneous provinces, the Shatsky Rise, began to be erupted in the region now occupied by French Polynesia. Large-scale volcanism in the central Pacific continued through the Cretaceous and the Cenozoic. The sustained volcanism, along with details of the clade distributions, both suggest that the Coprosminae have persisted in the central Pacific by survival of metapopulations on individually ephemeral islands. It is also likely that vicariance of metapopulations has taken place, mediated by processes such as the subsidence of the Pacific seafloor by thousands of metres, and rifting of active arcs by transform faults. It is sometimes argued that a vicariance origin is unlikely for groups on young, oceanic islands that have never been connected by continuous land, but metapopulation vicariance does not require physical contact between islands.
