The genus Callicarpa (Lamiaceae) on Borneo

Abstract

The Bornean species of Callicarpa (Lamiaceae) are revised. Twenty three species are recognized: of these, four are described as new (C. argentii, C. coriacea, C. subaequalis and C. teneriflora) and two are raised to species level from variety (C. endertii and C. hispida). All 23 species described are assessed for World Conservation Union (IUCN) conservation status. Distribution maps and an identification key are provided. The historic confusion between the genera Geunsia and Callicarpa is discussed. Geunsia is included as a synonym of Callicarpa based on the examination of morphological characters and molecular data. Geunsia is suggested to be nested within Callicarpa based on phylogenetic analyses of nuclear ribosomal internal transcribed spacer (nrITS), partial matK and trnD-T sequences of 30 taxa using maximum parsimony. © 2009 The Linnean Society of London.
