“…We recognize only 25 of the 47 species treated by Cogniaux (1891) and relegate a total of 44 epithets to synonymy. Since that time selected species have been included in many regional checklists or geographically defined local floras (Harley & Simmons 1986;Semir & Martins 1987;Martins 1991;Woodgyer 1995;Munhoz & Proença 1998: Romero & Martins 2002Woodgyer et al 2003;Matsumoto & Martins 2005;Rodrigues 2005;Santos & Silva 2005;Faria et al 2006;Hatschbach et al 2006;Chiavegatto & Baumgratz 2007;Drummond et al 2007;Kinoshita et al 2007;Faria 2008;Silva & Romero 2008;Alves & Kolbek 2009;Martins et al 2009a;Martins et al 2009b;Santos et al 2009;Meirelles & Goldenberg 2012;Forzza et al 2013;Goldenberg et al 2014;Maia & Goldenberg 2014;Pirani et al 2015;Versiane et al 2016;Pacifico 2017).

A systematic monograph is presented for Lavoisiera, a Brazilian endemic genus of 41 species that is centered in the campo rupestre ecoregion in the Brazilian Planalto south of the Amazon basin, mostly west of the Mata Atlântica (Atlantic Rainforest), and east of the Pantanal. The stronghold for species diversity is the state of Minas Gerais with 36 species, 30 of which are endemic there. This study represents the first comprehensive monograph of the genus based on field work across its distributional range, complemented by examination of over 3620 specimens from 35 herbaria. An evaluation of taxonomic characters used in the long-standing sectional classification of the genus has led to its abandonment because it is based on artificial characters and does not provide a sound working hypothesis of infrageneric relationships. Eight new species are described: L. arachnoidea, L. belinelloi, L. canastrensis, L. daviesiana, L. minima, L. rundeliana, L. setosa, and L. vestita; lectotypifications are provided for L. caryophyllea, L. chamaepitys, L. glandulifera, L. pulchella, and L. senae; and 44 epithets are relegated to synonymy. An identification key, full synonymy, descriptions, habitat and phenological information, distribution maps, diagnostic illustrations, images of representative species in the field, and geospatial conservation assessments are provided for all species based on IUCN criteria. SEM images of seed morphology are presented for nearly half of the species along with camera lucida drawings of meiotic chromosome figures for selected species, and an index to numbered collections examined.Key words: campo rupestre, Cerrado biome, conservation, endemism, Myrtales, neotropics ResumoApresentamos uma monografia sistemática para Lavoisiera, um gênero brasileiro endêmico com 41 espécies, cuja ocorrência é centrada na ecorregião de campo rupestre no Planalto Brasileiro, ao sul da Bacia Amazônica, principalmente a oeste da Mata Atlântica, e a leste do Pantanal.

“…They are also appreciated for fresh consumption, besides being a food source for the wild fauna. Some parts of the plant are used to prepare folk medicine, and the latex extracted from its trunk is used in the production of rubber (SILVA JÚNIOR, 2004;SILVA;ARAÚJO;ROCHA, 2011;SANTOS et al, 2013).…”

-This study aimed to characterize three natural populations of mangabeira (Hancornia speciosa) located in parts of the Cerrado in the region of Porto Nacional, State of Tocantins, as well as to evaluate phenotypic variability in individual plants based on the physicochemical properties of their fruits. Ten genotypes were selected from each population, and 20 fruits of each genotype were collected for analysis. Fruits were analyzed for transverse and longitudinal diameters, total mass, pulp mass and yield, and number and fresh mass of seeds. Two seeds were taken from each fruit for the measurement of longitudinal and transverse diameter and thickness. Furthermore, pH and soluble solids were measured in the total pulp of each genotype. Descriptive statistics were performed on the data from morphological characterization, and populations were compared by the Kruskal-Wallis test, followed by Dunn's test at 5% probability level. The relationship between variables was estimated by the Spearman's correlation coefficient. Phenotypic variability was verified using the principal component analysis. All three natural populations of mangabeira investigated here exhibited similar characteristics regarding fruit morphology and pH. Significant differences were detected only in the transverse diameter of the seed (Canaã had the highest value) and for total soluble solids content (Providência had the highest value). Significant correlations were found for corresponding morphological variables and pH in each population, except for several negative correlations that were observed in the Canaã population, which produced more homogeneous fruit. The Providência population presented the largest and most massive fruit. The greatest phenotypic variabilities were observed in the São Judas Tadeu and Providência populations.Keywords: Apocynaceae.

CARACTERIZAÇÃO E VARIABILIDADE FENOTÍPICA DE POPULAÇÕES NATURAIS DE MANGABEIRA NO ESTADO DO TOCANTINSRESUMO -O presente estudo teve como objetivo caracterizar três populações naturais de mangabeira (Hancornia speciosa Gomes) localizadas em áreas de Cerrado na região de Porto Nacional-TO e estudar a variabilidade fenotípica através de atributos físico-químicos de frutos. Foram selecionados dez genótipos em cada população e coletados vinte frutos de cada genótipo para análise. Nos frutos foram mensurados: o diâmetro transversal e longitudinal, a massa total, a massa e o rendimento de polpa, o número de sementes e a massa fresca das sementes. De cada fruto foram retiradas duas sementes e mensurados o diâmetro longitudinal, transversal e espessura. Da polpa total de cada genótipo foram mensurados o pH e sólidos solúveis. Para caracterização morfológica foi realizada estatística descritiva, a comparação entre as populações foi realizada através do teste de Kruskal-Wallis seguido do teste de Dunn a 5% de probabilidade. A relação entre as variáveis foi estimada pelo coeficiente de correlação de Spearman. Para o estudo da variabilidade fenotípica foi reali...
