Revisão taxonômica do gênero Ossaea DC. (Melastomataceae) no Brasil

  title={Revis{\~a}o taxon{\^o}mica do g{\^e}nero Ossaea DC. (Melastomataceae) no Brasil},
  author={Maria Souza},
In the present work a taxonomic revision of the Brazilian species of Ossaea DC. (Melastomataceae) is presented. The study was carried out using material from 54 national and foreign herbaria, and from field observations. The circunscription of Ossaea is discussed and this genus is accepted. Pentossaea W. Judd is synonymized under Ossaea. The morphological study of the species has analysed the externai morphology, and also other data, such as anatomical characters of the leaves and flowers and… 


A revision of Pterolepis (Melastomataceae: Melastomeae)
The main diagnostic feature of the genus are branched emergences in the intercalycine sinuses but these are variable among the species and also occur in many paleotropical and two neotropical species, casting some doubt on their taxonomic value above the species level.
A revision of Rhynchanthera (Melastomataceae)
The neotropical genus Rhynchanthera (Melastomataceae, Microlicieae) is revised, and 15 of the 84 proposed taxa are recognized; two species are excluded from the genus. The group consists of subshrubs
Polysporangiate Anthers: Described for the First Time in Melastomataceae
During the preparation of the Melastomataceae account for the Flora of the Pico das Almas, in the state of Bahia, Brazil, anthers of an apparently polysporangiate nature were encountered in two species of Chaetostoma, a phenomenon hitherto unknown in the family as a whole.
Diversidade taxonômica e padrões de distribuição geográfica em Picramnia (Simaroubaceae) no Brasil
In the neotropical genus Picramnia Sw., 19 species have been recognized for Brazil, from which 12 are exclusively brazilian. The main patterns of variation and geographical and ecological
Phylogeny and classification of the Melastomataceae and Memecylaceae
A phylogeny in which there are two major lineages in the Melastomataceae and a clearly distinct Memecylaceae is suggested, which implies an east Gondwanian origin of the family.
Wood anatomy of the Neotropical Melastomataceae
The wood anatomy of 47 genera of the neotropical Melastomataceae is described in detail and the relationship between wood anatomical characters and habit and habitat, as well as possible phylogenetic trends in the family and classification of theNeotropical tribes are discussed.
Flora of Dominica, Part 2: Dicotyledoneae
The paper used in this publication meets the minimum requirements of the American National Standard for Permanence of Paper for Printed Library Materials 239.48-1984.
Pollen Characters in Relation to the Delimitation of Myrtales
Pollen grains representative of the Lythraceae, Punicaceae, Sonneratiaceae, Trapaceae, Oliniaceae, Combretaceae, Alzateaceae, Penaeaceae, Crypteroniaceae, Melastomataceae, Myrtaceae and Onagraceae were examined with scanning (SEM) and transmission (TEM) electron microscopy.
A note on stomatal types and crystals in the leaves of Melastomataceae
Original data on leaf crystals and stomatal types in 25 genera of Melastomataceae are presented and the classification of the family as modified by Van Vliet et al. (1981, this issue) is discussed.
On the whole, seed morphology confirms the existence of five tribes among the neotropical capsular-fruited Melastomataceae and provides interesting evidence for generic relationships; however, it also calls into doubt the taxonomic disposition of certain genera and the delimitation of these five tribes.
