Mapping of discrete traits and climatic variables onto a six species tree of Malagasy <i>Canarium</i>.

<p>(A) Suitable dry- and wet-forest habitat for <i>Canarium</i> based on remote sensing data from the Atlas of Madagascar (Royal Botanic Garden, Kew; <a href="http://www.vegmad.org" target="_blank">http://www.vegmad.org</a>). (B) Phylogeny for the six clades favored under our integrative species delimitation analyses. Colored edges on the tree show ancestral reconstructions of climatic preferences based on the first axis from outlying mean index niche separation analyses. (C) Discrete morphological traits are shown with filled circles for (1) leaf pubescence (from light to dark = glabrous, flexuous hairs evenly distributed, erect hairs in tufts, erect hairs distributed evenly); (2) fruit color (from light to dark: maturing green, maturing brown, maturing purple); and (3) stamen position (white = inserted at disk base, black = inserted outside of disc, ? = unknown). (D) Taxonomic labels associated to the six clades supported under our integrative species delimitation approach.
