| A poaia (Psychotria ipecacuanha), Rubiaceae, é importante espécie medicinal, nativa da América, com a maior área de ocorrência no estado de Mato Grosso, principalmente no município de Cáceres. O objetivo neste trabalho foi verificar o efeito de substratos, da posição de estacas de raiz, e de tipos de estacas na propagação de P. ipecacuanha. No primeiro experimento foram usadas estacas de raiz com 2 cm de comprimento no delineamento experimental de blocos ao acaso, no esquema de parcela subdividida 2 x 2, sendo duas posições (vertical e horizontal) e dois substratos (areia e espuma fenólica), com 15 repetições com 15 estacas cada. No segundo experimento introduzimos estacas basais e apicais da raiz e da parte aérea nos substratos areia, comercial para... |

| In Mexico, medicinal plants are widely used. The use of Randia aculeata by healers against snakebites has never been scientifically tested in relation to possible effects on blood parameters and muscle tissue damage. Interviews were carried out in Jamapa, Veracuz, Mexico, with local residents to collect information about the traditional use of Randia aculeata. In this locality, seven pieces of fruit from the plant are mixed in a liter of alcohol, and then administered orally against snakebites. By using histological techniques and a murine model, we explored its cytoprotective properties against the effects of Crotalus simus and Bothrops asper venoms. Possible protections provided by the plant against tissue damage to skeletal and cardiac muscles and... |

| In the 1990s Rubiaceae became a hot spot for systematists, mainly due to the comprehensive treatment of the family by Robbrecht in 1988. Next to the exploration of macromolecular characters to infer the phylogeny, the palynology of Rubiaceae finally received the attention it deserves. This article aims to present a state-of-the-art analysis of the systematic palynology of the family. The range of variation in pollen morphology is wide, and some of the pollen features are not known from other angiosperm taxa; e.g., a looplike or spiral pattern for the position of apertures in pantoaperturate grains. We compiled an online database at the generic level for the major pollen characters and orbicule presence in Rubiaceae. An overview of the variation is... |

| According to current generic delimitations, supported by wood anatomy, palynology, and recent molecular phylogenies, Antirhea, traditionally treated as a Pantropical genus, is instead restricted to the Paleotropics. At the same time, the Neotropical species traditionally positioned in Antirhea should be positioned in Stenostomum. Following these definitions, Stenostomum is a genus with most of the species present in the Caribbean Region, and two species present in the Guianas, namely S. acreanum and S. guianensis, distributed throughout the Amazon Basin. In addition, according to these new generic delimitations, two species previously positioned in Guettarda and Antirhea need to be transferred to Chomelia, as C. triflora and C. ulei. |

| Based on herbarium collections, the Malesian species of the genus Lasianthus are revised. A total of 131 species including 5 subspecies and 6 varieties are recognized from the Malesian region, of which 41 species, 3 subspecies and 3 varieties are described as new, and 3 new combinations are made for varieties. 22 species names and 15 variety names are reduced to synonyms. Ten species names and 2 varieties are treated as dubious mainly because their types cannot be traced. Additionally, 11 species are further excluded from Lasianthus. All species are described and a key to Malesian Lasianthus is given. |

| Colletoecema magna, a new species from the Ngovayang Massif (southern Cameroon) is described and illustrated. A comparative morphological study illustrates the similar placentation and fruit anatomy of the novelty and Colletoecema dewevrei, the only other species of the genus. Colletoecema magna essentially differs from C. dewevrei by its sessile flowers and fruits, the corolla tube that is densely hairy above the insertion point of the stamens and the anthers that are included. Further characters that separate the novelty are its larger leaves, more condensed inflorescences, and larger fruits. Its position within Colletoecema is corroborated by atpB-rbcL and rbcL chloroplast sequences. The relationships among the basal lineages of the subfamily... |

| Systematic wood anatomy of the tribe Guettardeae (Rubiaceae). The wood anatomy of nearly all genera of the Guettardeae (Rubiaceae, Guettardoideae) has been examined, and in this respect the tribe is heterogeneous. Suggestions are made for a delimitation of the tribe. Guettarda, Bobea, Antirhea, Malanea and Chomelia Jacq. are sufficiently similar in their wood anatomical characters to warrant retention in the same tribe. Machaonia, Timonius and Dichilanthe are anomalous. Suggestions are given for taxonomic revisions of some genera based on their wood anatomy. |

| Changes in generic concepts and delimitation resulted in 80 genera (6 of which are cultivated) of Philippine Rubiaceae. Generic descriptions of all genera are coded in DELTA format (Version 2000) and translated by the directive CONFOR into INTKEY database for interactive identification and information retrieval. The descriptions incorporate mostly compiled data of Philippine Rubiaceae species and observations on over 130 characters. Recently accepted classification (subfamily, tribes, and subtribes) and significant characters defined by Robbrecht (1988, 1993) are appended to the generic descriptions. The database is available on the World Wide Web at http://www.uni-bayreuth.de/ departments/planta2/wgl/delta_ru/index.html. |
