| The wood structure of 78 species from 27 genera representing the woody primuloids (Maesaceae, Myrsinaceae, and Theophrastaceae) was investigated using light microscopy (LM) and scanning electron microscopy (SEM). Results indicated that the ray structure, the nature of mineral inclusions, and the occurrence of breakdown areas in rays can be used to separate the three primuloid families from each other. Within Ericales, the presence of exclusively multiseriate rays is synapomorphic for Myrsinaceae and Theophrastaceae, and the occurrence of breakdown areas in rays is synapomorphic for Myrsinaceae. Within Myrsinaceae, the wood structure of the mangrove genus Aegiceras differs because it has short vessel elements that are storied, non-septate fibers, a... |

| Os tipos de placentação e de pré-floração têm sido utilizados para a distinção dos gêneros Ardisia Swartz, ao qual tem sido atribuído placentação plurisseriada e pré-floração imbricada ou quincuncial, e Stylogyne A.DC., ao qual tem sido atribuído placentação unisseriada e pré-floração contorta. Entretanto, a análise de dez espécies destes gêneros revelou a inconsistência destes caracteres. Também foi constatada a impossibilidade de observar diferenças no tipo de placentação em espécimes com poucos óvulos. Propõe-se, portanto, o restabelecimento da circunscrição de Ardisia, incluindo o gênero Stylogyne, conforme adotado por Miquel, em 1856 e Handro, em 1969. Desta forma, Ardisia ambigua Mart. é o nome válido para S. ambigua (Mart.) Mez e Ardisia martiana... |

| ABSTRACT Although a species’ sexual system may influence the genetic diversity of its populations in their natural environment, there have been few such studies involving indigenous species of the Atlantic Forest. Here we study Myrsine coriacea, a dioecious tree widely used in reforestation programs despite a lack of information about its natural interpopulation genetic variation. To address this knowledge gap, intra- and interpopulation genetic diversity were measured for male and female individuals of ten natural populations using ISSR markers. Greater intrapopulation genetic diversity indicated interpopulation gene flow, regardless of isolation and distance between populations. Multivariate analyses detected significant differences in genetic diversity... |

| Dirphia dolosa Bouvier, 1929 is an endemic moth from southern Brazil, with available information restricted to occurrence data, natural host plant and adult morphology. This study describes bionomic peculiarities of this species, obtained from observations of larval aggregations in the field and in the laboratory. Data on all developmental stages are presented and compared with those of other Hemileucinae. D. dolosa present a facultative pupal diapause and may have two generations per year under the climatic conditions of the Rio Grande do Sul State, Brazil. |
