Based on herbarium material collected in Bolivia, a species new to science, Philibertia woodii H.A. Keller & Goyder is described and illustrated here. The similar its vegetative floral morphology latiflora (Griseb.) Goyder, P. longistyla speciosa (Malme) Goyder. allows the list of taxa genus be increased 45.

Abstract We performed the taxonomic-floristic survey of subtribe Gonolobinae for state Ceará, as part “Flora do Ceará: knowing to conserve” project. The study was based on comparative analysis morphological characters, specialized bibliography, well photos type-collections. In six species two genera were registered: Gonolobus rostratus, Matelea denticulata, M. endressiae, ganglinosa, harleyi, a...

BACKGROUND AND AIMS The number of genera included in Apocynaceae subfamily Periplocoideae is a matter of debate. DNA sequences are used here as an independent dataset to clarify generic relationships and classification of the tuberous periplocoid genera and to address the question of the phylogenetic interpretation of pollinia formation in Schlechterella. METHODS Representatives of nearly all...

Ambelania occidentalis is routinely used in folk medicine for treating gastrointestinal disorders, even though there have been no safety trials. We evaluated the genotoxic potential of hydro-alcoholic extracts of this plant in mice; induced DNA damage was assessed in peripheral blood leukocytes and micronucleus induction was assessed in polychromatic erythrocytes from bone marrow. The extract w...

The dispersal ecology of Stemmadenia donnell-smithii was studied in the tropical dry forest zone of northwestern Costa Rica. Fruit was most abundant late in the dry season and was eaten by 22 species of birds, many of which are primarily insectivorous. Stomach-content analyses substantiated our observations. Total crop size per tree and rate of fruit opening were greatest in pasture-edge trees ...
