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.

Apomixis does not affect visitation to flowers of Melastomataceae, but pollen sterility does

2015

Apomixis is an asexual seed reproduction mechanism thorough which embryos are originated from material tissues inside the ovules, without precedent fertilisation. It allows plants to colonise new habitats, even in places where flower visitors are scarce or where plants are isolate. Apomixis seems to be related to pollen sterility and, in species with flowers that offer pollen as a reward for pollinators, the amount or quality of the pollen offered by these species may influence the amount of the visits and specific composition of the visitors. In order to test this hypothesis, we studied breeding systems of 16 species of Melastomataceae and their flower visitors, evaluating composition and abundance of the visits to apomictic and sexual species. Apomictic plants with no viable pollen or with pollen with low viability did not receive visits from pollinators, and consequently probably produce strictly apomictic fruits. On the other hand, apomictic and sexual plants with high pollen viability do receive visits; in this case, apomictic plants may produce fruits and seeds through both sexual and apomictic methods. The species composition of insects visiting Melastomataceae with high pollen viability was similar, regardless of whether the plants were apomictic or not. It seems that pollen viability levels are important to determine visits to the flowers irrespective of breeding system.
