The general-lineage species concept, which defines species as separately evolving metapopulation lineages, considers multiple lines of evidence to identify lineages and delimit species boundaries. Here, we apply the general-lineage concept to the New Zealand endemic Myosotis petiolata Hook.f. (Boraginaceae) species complex, to test its usefulness in the New Zealand Myosotis L. species radiation. We aimed to determine whether the complex contains separately evolving lineages to assess the criteria of monophyly, distinct genotypic clusters and fixed morphological differences by using amplified fragment length polymorphism (AFLP) and morphological data. The use of multiple criteria to identify separately evolving lineages within the M. petiolata complex was effective, but the different criteria were satisfied to varying degrees. Species rank is recommended for each of the currently recognised varieties as Myosotis pottsiana (L.B.Moore) Meudt, Prebble, R.J.Stanley &amp; Thorsen (comb. &amp; stat. nov.), M. pansa (L.B.Moore) Meudt, Prebble, R.J.Stanley &amp; Thorsen (comb. &amp; stat. nov.) and M. petiolata Hook.f. (North Island individuals only). A new allopatric subspecies, M. pansa subsp. praeceps Meudt, Prebble, R.J.Stanley &amp; Thorsen (subsp. nov.), is also described. The distinguishing morphological characters and conservation status of each species are discussed. In addition, the low genetic diversity revealed in our population genetic analyses, coupled with few, fluctuating, disjunct populations, underscores the conservation priority of these three rare endemic New Zealand species.</p>

Major open issues are the placement and affinities of Boraginaceae s.str. in Boraginales and the major clades of the family, with especially the large tribes Cynoglosseae and Eritrichieae repeatedly retrieved as non-monophyletic groups, and the doubtful monophyly of several larger genera, especially Cynoglossum and Omphalodes. The present study addresses and solves these questions using two plastid markers (trnL–trnF, rps16) on the basis of a sampling including 16 outgroup taxa and 172 ingroup species from 65 genera. The phylogeny shows high statistical support for most nodes on the backbone and on the individual clades. Boraginaceae s.str. are sister to African Wellstediaceae, Wellstediaceae–Boraginaceae s.str. is sister to African Codonaceae. Echiochileae are retrieved as sister to the remainder of Boraginaceae s.str., which, in turn, fall into two major clades, the Boragineae–Lithospermeae (in a well-supported sister relationship) and the Cynoglosseae s.l. (including Eritrichieae). Cynoglosseae s.l. is highly resolved, with Trichodesmeae (incl. Microcaryum, Lasiocaryum) as sister to the remainder of the group. Eritrichieae s.str. (Eritrichium, Hackelia, Lappula) are resolved on a poorly supported polytomy together with the Omphalodes-clade (incl. Myosotidium, Cynoglossum p.p.), and the Mertensia-clade (incl. O. scorpioides, Asperugo). The Myosotideae (Myosotis, Trigonotis, Pseudomertensia) are retrieved in a well-supported sister-relationship to the core-Cynoglosseae, the latter comprising all other genera sampled. Cynoglossum is retrieved as highly para- and polyphyletic, with a large range of generic segregates embedded in Cynoglossum, but other species of Cynoglossum are sister to Microula or to the American “Eritrichieae” (Cryptantha and allied genera). Representatives of the genus Cynoglossum in its current definition are segregated onto six independent lineages, members of Omphalodes onto three independent lineages. At least 11 of the genera here sampled are deeply nested in other genera. The data show that individual details of nutlet morphology (e.g., winged margins, glochidia) are highly homoplasious. Conversely, a complex of nutlet characters (e.g., characters of the gynobase and cicatrix together with nutlet orientation and sculpturing) tends to circumscribe natural units. Geographical distribution of major clades suggests that the family originated in Africa and western Asia and radiated to eastern Eurasia, with several independent dispersal events into Australia and the New World.
