ABSTRACT Background. Mexico is one of the most floristically rich countries in the world. Despite significant contributions made on the understanding of its unique flora, the knowledge on its diversity, geographic distribution and human uses, is still largely fragmented. Unfortunately, deforestation is heavily impacting this country and native tree species are under threat. The loss of trees has a direct impact on vital ecosystem services, affecting the natural capital of Mexico and people's livelihoods. Given the importance of trees in Mexico for many aspects of human well-being, it is critical to have a more complete understanding of their diversity, distribution, traditional uses and conservation status. We aimed to produce the most comprehensive database and catalogue on native trees of Mexico by filling those gaps, to support their in situ and ex situ conservation, promote their sustainable use, and inform reforestation and livelihoods programmes. Methods. A database with all the tree species reported for Mexico was prepared by compiling information from herbaria and reviewing the available floras. Species names were reconciled and various specialised sources were used to extract additional species information, i.e.

Hernández, Mario Sousa and Helga Ochoterena Herbario Nacional de México, Departamento de Botánica, Instituto de Biología, Universidad Nacional Autónoma de México. Apartado postal 70- 233, 04510 México D. F., Mexico. [email protected] Abstract. Trees or tree-like plants are defined here broadly as perennial, self-supporting plants with a total height of at least 5 m (without ascending leaves or inflorescences), and with one or several erect stems with a diameter of at least 10 cm. We continue our compilation of an updated list of all native Mexican tree species with the dicotyledonous families Asteraceae (36 species, 39% endemic), Leguminosae with its 3 subfamilies (449 species, 41% endemic), and Rubiaceae (134 species, 24% endemic). The tallest tree species reach 20 m in the Asteraceae, 70 m in the Leguminosae, and also 70 m in the Rubiaceae. The species-richest genus is Lonchocarpus with 67 tree species in Mexico. Three legume genera are endemic to Mexico (Conzattia, Hesperothamnus, and Heteroflorum). The appendix lists all species, including their original publication, references of taxonomic revisions, existence of subspecies or varieties, maximum height in Mexico, and endemism status. Key words: biodiversity, flora, tree definition. Resumen. Las plantas arbóreas o arborescentes se definen aquí en un sentido amplio como plantas perennes que se pueden sostener por sí solas, con una altura total de al menos 5 m (sin considerar hojas o inflorescencias ascendentes) y con uno o varios tallos erectos de un diámetro de al menos 10 cm.

  • A Phylogeny of Legumes (Leguminosae) Based on Analysis of the Plastid Matk Gene Resolves Many Well-Supported Subclades Within the Family1
    American Journal of Botany 91(11): 1846±1862. 2004. A PHYLOGENY OF LEGUMES (LEGUMINOSAE) BASED ON ANALYSIS OF THE PLASTID MATK GENE RESOLVES MANY WELL-SUPPORTED SUBCLADES WITHIN THE FAMILY1 MARTIN F. W OJCIECHOWSKI,2,5 MATT LAVIN,3 AND MICHAEL J. SANDERSON4 2School of Life Sciences, Arizona State University, Tempe, Arizona 85287-4501 USA; 3Department of Plant Sciences, Montana State University, Bozeman, Montana 59717 USA; and 4Section of Evolution and Ecology, University of California, Davis, California 95616 USA Phylogenetic analysis of 330 plastid matK gene sequences, representing 235 genera from 37 of 39 tribes, and four outgroup taxa from eurosids I supports many well-resolved subclades within the Leguminosae. These results are generally consistent with those derived from other plastid sequence data (rbcL and trnL), but show greater resolution and clade support overall. In particular, the monophyly of subfamily Papilionoideae and at least seven major subclades are well-supported by bootstrap and Bayesian credibility values. These subclades are informally recognized as the Cladrastis clade, genistoid sensu lato, dalbergioid sensu lato, mirbelioid, millettioid, and robinioid clades, and the inverted-repeat-lacking clade (IRLC). The genistoid clade is expanded to include genera such as Poecilanthe, Cyclolobium, Bowdichia, and Diplotropis and thus contains the vast majority of papilionoids known to produce quinolizidine alkaloids. The dalbergioid clade is expanded to include the tribe Amorpheae. The mirbelioids include the tribes Bossiaeeae and Mirbelieae, with Hypocalypteae as its sister group. The millettioids comprise two major subclades that roughly correspond to the tribes Millettieae and Phaseoleae and represent the only major papilionoid clade marked by a macromorphological apomorphy, pseu- doracemose in¯orescences.

Note that the list of genera is not exhaustive and the absence of a genus from a particular island group simply means that no reference was found to its occurrence in rainforest habitat in the references used (i.e. the genus may still be present in rainforest or may occur in that locality in other habitats). As the definition of rainforest can vary considerably among localities, for the purpose of this paper we considered rainforests to be terrestrial forest communities, composed largely of evergreen species, with a tree canopy that is closed for either the entire year or during the wet season.
