    Boliviadendron, a new segregate genus of mimosoid legume (Leguminosae, Caesalpinioideae, mimosoid clade) narrowly endemic to the interior Andean valleys of Bolivia

    Phylogenetic analyses of DNA sequence data sampling all species of <i>Leucochloron</i> alongside representatives of genera of the Inga and Albizia clades of the larger ingoid clade of mimosoid legumes (sensu Koenen et al. 2020) confirm the non-monophyly of the genus <i>Leucochloron</i>. We show that <i>Leucochloronbolivianum</i> is placed in the Albizia clade, while the remaining four species of <i>Leucochloron</i> are placed in the Inga clade, in line with previous results. To rectify this non-monophyly, <i>L.bolivianum</i> is segregated as the new genus, <i>Boliviadendron</i>, with a single species, <i>Boliviadendronbolivianum</i>, narrowly endemic to the interior Andean valleys of Bolivia. We illustrate this new segregate genus, present a map of its distribution and discuss the striking lack of morphological distinctions between <i>Boliviadendron</i> and <i>Leucochloron</i>, as well as the phylogenetic and morphological affinities of <i>Boliviadendron</i> to the genera <i>Enterolobium</i> and <i>Albizia</i>.

    Bolivian Mimosa (Leguminosae, Mimosoideae): three new species and a species checklist
    (Q15088586, 2016) Margoth Atahuachi Burgos; M. Leontien van der Bent; John R. Wood; Gwilym P. Lewis; Colin E. Hughes
    Three new species of Mimosa (Leguminosae, Mimosoideae) M. chiquitaniensis, M. chochisensis and M. rastrera, two of them endemic to Bolivia, and the third also occurring in Brazil, are described and an annotated species checklist for the genus in Bolivia is presented. This brings the tally of species of Mimosa recorded from Bolivia to 55 (plus five doubtful species to be confirmed), an increase of ca. 50% since the monographic account of the genus published just over 25 years ago.
