Lecythis marcgraaviana (Lecythidaceae), a species previously placed in synonymy of L. pisonis, is resurrected and described in detail for the first time. A neotype, discussion of the history of this species, taxonomic notes, images, and an identification key to the species of the Lecythis pisonis clade from eastern Brazil are provided. This tree or shrub occurs in coastal Atlantic Forest between the states of Espírito Santo and Rio Grande do Norte. Morphologically, L. marcgraaviana is most similar to L. lanceolata and L. pisonis.

This work evaluates the conservation status of the 22 species of Lecythidaceae native to eastern Brazil. Assessments based on current IUCN criteria, distribution maps, and an identification key to the native and non-native species from the area are provided. The results of this study suggest that over half of the species are threatened (vulnerable or endangered), four species should be added to the IUCN Red List, and the status of seven species currently on this list should be changed. It was found that nearly all collections of endangered species are from or occur within 20 km of a reserve, which clearly shows that protected areas are of vital importance for the survival of most endangered Lecythidaceae from this region.

The morphological features of all clades of neotropical Lecythidaceae subfam. Lecythidoideae (Brazil nut family) with actinomorphic androecia (Allantoma, Grias, Gustavia) as well as three clades with zygomorphic androecia (Cariniana, Couroupita, and Couratari) are described. These clades are those that were recovered by a phylogeny based on molecular data, and all, except Allantoma and Cariniana, have been recognized as genera without changes for over a hundred years. The latter two genera have recently been circumscribed such that they now also represent monophyletic clades; thus, the authors conclude that the clades discussed in this paper represent well-defined genera based on both morphological and molecular data. Morphological descriptions of these six clades of the non-Bertholletia clade are included and a key to the 16 clades of New World Lecythidaceae is presented.

Abstract An updated inventory of Brazilian seed plants is presented and offers important insights into the country's biodiversity. This work started in 2010, with the publication of the Plants and Fungi Catalogue, and has been updated since by more than 430 specialists working online. Brazil is home to 32,086 native Angiosperms and 23 native Gymnosperms, showing an increase of 3% in its species richness in relation to 2010. The Amazon Rainforest is the richest Brazilian biome for Gymnosperms, while the Atlantic Rainforest is the richest one for Angiosperms. There was a considerable increment in the number of species and endemism rates for biomes, except for the Amazon that showed a decrease of 2.5% of recorded endemics. However, well over half of Brazillian seed plant species (57.4%) is endemic to this territory. The proportion of life-forms varies among different biomes: trees are more expressive in the Amazon and Atlantic Rainforest biomes while herbs predominate in the Pampa, and lianas are more expressive in the Amazon, Atlantic Rainforest, and Pantanal. This compilation serves not only to quantify Brazilian biodiversity, but also to highlight areas where there information is lacking and to provide a framework for the challenge faced in conserving Brazil's unique and diverse flora.

The utility of placentation in the circumscription of ge nera of New World Lecythidaceae (Brazil nut family). The placentation of the 16 known clade s of New World Lecythidaceae and several species of Old World Barringtonia are illustrated and described. The authors conclude that the family possesses axile placentation but an SEM study o f flower development may modify that conclusion. They also restrict the term placenta to all tissue derived from the same carpel to which the ovules are attached. The more basal genera are often defined by placental features as well as by morphological apomorphies and sometimes by molecular data. In contrast, Eschweilera and Lecythis , based on molecular data, are made up of three and five differ ent clades, respectively. Of the three Eschweilera clades, the Eschweilera tetrapetala clade can be separated from the two other clades of the genus by having more than one row of ovules per locule. In contrast, the other two clades of Eschweilera (the E. integrifolia and E. parvifolia clades) posses a single row of ovules in each locule. We conclude that placental data support the segregation of the E. tetrapetala clade as a separate genus while the segregation of the latter two clades is not suppor ted by placental data, even though morphological data support their separation at some taxonomic le vel. Within the currently circumscribed Lecythis , the Lecythis pisonis . and L. corrugata clades are supported by weak placental data; nevertheless, morphological and molecular data support rec ognizing them as distinct genera. The Lecythis ollaria clade, which includes the type species, is supported by mor phological and molecular (100% bootstrap support) data and, if Lecythis were restricted to this clade, the genus would be reduced from 26 to three species. In contrast, the L. poiteaui and L. chartacea clades recovered in this study are not supported by placental or mol ecular data and morphological support

Lecythis ibiriba (Lecythidaceae), a new combination, is described, illustrated, and discussed. This species occurs as a shrub or small- to medium-sized tree that grows in the Atlantic Forest of northeastern Brazil. Lecythis ibiriba differs from most species of Lecythis by having seeds with poorly developed basal arils and stalked vestigial stamens that are curved but not swept inward. Morphologically, it is similar to L. lurida; however, differences in the bark, leaves, flowers, and fruits justify its recognition as a separate species.
