PHYLOGENY AND SYSTEMATICS OF THE RAUVOLFIOIDEAE (APOCYNACEAE) BASED ON MOLECULAR AND MORPHOLOGICAL EVIDENCE1
Based on the phylogeny, simple style-heads, syncarpous ovaries, indehiscent fruits, and winged seeds have evolved in parallel numerous times and a revised classification is offered for the subfamily, its tribes, and inclusive genera. Expand
Eight New Species of Mandevilla Lindley (Apocynaceae, Apocynoideae) from Brazil
Eight new species of Mandevilla Lindley are described and illustrated, six of them rare and endemic, occur in eastern Brazil, and one is a small shrub endemic to Maciço da Borborema, in northeastern Brazil. Expand
Calycine colleters of seven species of Apocynaceae (Apocynoideae) from Brazil
A larger secretory surface, together with the extension of the secretory phase in adult flowers, were major shifts in the calycine colleters of Apocynaceae, and are possibly correlated with the functional and ecological aspects of these organs. Expand
Tribal and intergeneric relationships of Mesechiteae (Apocynoideae, Apocynaceae): evidence from three noncoding plastid DNA regions and morphology.

A maximum parsimony analysis was conducted based on DNA sequences and morphological data for 23 taxa of Mesechiteae and 11 taxa from other tribes of Apocynoideae to test the monophyly of the tribe and evaluate intratribal relationships. Expand
The Apocynaceae s. str. of the Carrancas Region, Minas Gerais, Brazil
Resumen en: The aims of the present work were to identify and characterize the species of Apocynaceae s. str. occurring in the Carrancas region, State of Minas Gera...
Functional morphology and wasp pollination of two South American asclepiads (Asclepiadoideae-Apocynaceae).
The detailed structure of the flowers revealed a complex system of guide rails and chambers precisely arranged in order to achieve effective pollinaria transport, which explains the differences in details of the functioning of the general pollination mechanism. Expand
Systematics and character evolution of Tabernaemontaneae (Apocynaceae, Rauvolfioideae) based on molecular and morphological evidence
420 new chloroplast DNA sequences from 104 species, including representatives of all satellite genera ever recognized in the Tabernaemontaneae, were analyzed phylogenetically to evaluate previous circumscriptions of TabernAemontana and test the sectional treatment ofTabernaEMontana, which was shown to be monophyletic. Expand
Brazilian Tabernaemontana genus: Indole alkaloids and phytochemical activities.
This review covers relevant references about Tabernaemontana species found in Brazil, its geographical distribution, occurrence of monoterpene alkaloids and phytochemical activities. Expand
Taxonomy of Aspidosperma Mart. (Apocynaceae, Rauvolfioideae) in the State of Pará, Northern Brazil
The goal of this work was to provide a taxonomic study of the Aspidosperma species occurring in the state of Para, northern Brazil, with the Baixo Amazonas Mesoregion presenting the largest number of species, and the Metropolitana de Belem mesoregions presenting the smallest number. Expand
IS MANDEVILLA (APOCYNACEAE, MESECHITEAE) MONOPHYLETIC? EVIDENCE FROM FIVE PLASTID DNA LOCI AND MORPHOLOGY1
Maximum parsimony analysis was conducted on a data set comprising DNA sequences from five plastid loci and morphological data for 65 taxa of Mesechiteae and its affinities to other genera in the tribe, and Mandevilla was found to be monophyletic, whereas Woodson's circumscription proved to be polyphyletic.
