RESUMO -O check-list atualizado das espécies de Euphorbiaceae s. str., Phyllanthaceae e Peraceae do estado de Mato Grosso do Sul é apresentado, baseado em dados da Lista de Espécies do Brasil, dos acervos de vários herbários, bem como de revisões e fl oras disponíveis. Para cada táxon é citada uma coleção testemunho do Mato Grosso do Sul, as macroregiões onde ocorre no estado (Cerrado, Chaco, Pantanal, Mata Atlântica) e sua distribuição geográfi ca total no Brasil. Para Euphorbiaceae s. str. foram reportados para o estado 154 espécies, para Phyllanthaceae 16 espécies e para Peraceae duas espécies. Palavras-chave: biodiversidade, Cerrado, Chaco, Mata Atlântica, Pantanal ABSTRACT -Checklist of Euphorbiaceae s. str., Phyllanthaceae and Peraceae from Mato Grosso do Sul, Brazil. An updated checklist of the families Euphorbiaceae s.str., Phyllanthaceae and Peraceae from the state of Mato Grosso do Sul is presented based on data from Lista das Espécies do Brasil, collections of several herbaria and fl oras and revisions available. For each taxon is cited a voucher specimen from MS, its area of occurrence (Cerrado, Chaco, Pantanal, Mata Atlantica) and its geographical distribution in Brazil. The following numbers of species were reported for each family in the state: Euphorbiaceae s. str. 154 species, Phyllanthaceae 16 species and Peraceae 2 species.

“…Microstachys serrulata is a widely distributed shrub (0.62 ± 0.16 cm height, [mean ± SD], n = 30) in Brazilian savanna (Fig. 1b), occurring in open areas as well as in the understory of riparian forests (Pscheidt & Cordeiro, 2012;Aleixo et al, 2017). Its fruits dry and open on the parent plant, primarily between March-April (Aleixo et al, 2017), and the seeds (3.75 ± 0.17 mm length, 0.52 ± 0.19 mg fresh seed mass, [mean ± SD], n = 40) fall unassisted (D.

1. Harvester ants are major seed predators in arid environments. However, given that many harvester ants are partly omnivorous and therefore potentially attracted to the elaiosomes of myrmecochorous seeds, it is unclear if these ants act as predators or dispersers when removing myrmecochorous seeds. 2. We describe the outcomes of interactions between the harvester ant, Pogonomyrmex naegelii, and myrmecochorous plant, Microstachys serrulata, in a Brazilian savanna. We: (i) evaluated the role of elaiosome in seed removal by P. naegelii; (ii) investigated the fate and viability of removed seeds; (iii) tested if soils associated with P. naegelii nests are nutrient‐enriched; (iv) compared seedling survival; and (v) the density of seedling and adult M. serrulata nearby to P. naegelii nests compared with those away from these nests (i.e. controls). 3. Rates of removal of M. serrulata seeds were two‐fold higher with elaiosomes than without. The ant attractant oleic acid was the dominant fatty acid in elaiosomes, but it was absent from seeds. Removed seeds are taken into nests, and Tetrazolium tests indicated that 95% of seeds remain viable. Soils associated with P. naegelii nests were not nutrient‐enriched, and seedling survival was similar nearby to P. naegelii nests compared with control areas. However, densities of both seedling and adult M. serrulata were higher nearby to P. naegelii nests than in control areas. 4. Our findings show that P. naegelii switches its role from seed predator for most plant species to be the dominant seed disperser for M. serrulata, playing a key role in the distribution of adult plants.

Euphorbiaceae has a large representation in the semi-arid region of Brazil, and is considered one of the families that characterize Caatinga. The aim of this study was to conduct a floristic survey of the family Euphorbiaceae to Serra Geral of Licínio de Almeida including identification key, descriptions, comments and illustrations. The area is located in Espinhaço Range and occupies a long area west of the municipality of Licínio de Almeida. A number of 51 species distributed in 14 genera were collected: Croton (23 spp.), Euphorbia (6 spp.), Microstachys (4 spp.), Manihot (3 spp.), Acalypha, Cnidoscolus, Dalechampia, Sebastiania e Stillingia (2 spp. each), Alchornea, Astraea, Gymnanthes, Maprounea and Tragia (1 sp. each). Three espécies are endemic to Bahia (Croton imbricatus, Microstachys uleana, Sebastiania catingae), four are new records to the State (Acalypha multicaulis, Euphorbia attastoma, E. setosa, and Stillingia trapezoidea).
