Reproductive biology of endemic Solanum melissarum Bohs (Solanaceae) and updating of its current geographic distribution as the basis for its conservation in the Brazilian Cerrado

The genus Solanum (family Solanaceae) includes more than 1400 species and has buzz-pollinated flowers with poricidal anthers. The present study aimed to describe the distribution, breeding system and pollination mechanism of Solanum melissarum, a species endemic to Brazil. The study of breeding system was conducted in an urban forest fragment in Jataí, GO. Distribution data were gathered from floristic surveys and digital plant databases. The floral morphology and the pollination mechanism were studied on through field observations and preserved flowers. The breeding system was determined through hand pollination treatments. The species has a distribution only in the Brazilian Atlantic forest coastal, and this study provides the first records of S. melissarum for the state of Goiás. The pendulous flowers have poricidal anthers close to the stigma, with membranous thecae joined by a connective bearing osmophores that attract males of Euglossa cordata bees. As they collect fragrances, the bees press the thecae and pollen is released through a bellows mechanism. Based on the hand-pollination treatments, this species is self-incompatible. Isolated forest fragments may not include enough pollinators to ensure the pollination of plants with specialized systems. However, they are essential for the conservation of species with interesting phytogeographic patterns, such as the vicariance observed in S. melissarum, and for the conservation of regional diversity.

Plantas medicinais referenciadas por raizeiros no município de Jataí, estado de Goiás

This study aimed to research medicinal plants referenced by “raizeiros” from Jatai-GO, showing the Reported Use Value (RUV) and connection with current phylogenetic levels. With nearly 200 years of history, Jatai is located in the Central Plateau of Brazil, Southwest Goias (17°52’53 ‘’S and 51°42’52’’W), where the main source of income is agribusiness. For the “raizeiros” selection and data collection the snowball method and semi-structured interview techniques were applied. The ethnospecies, used part, usage, method of preparation for estimatedReported Value of Use (VU). There were 515 related ethnopharmacological citations of 112 ethnospecies, mainly Fabideas, Lamideas and Campanulideas. Pe-de-perdiz (Croton antisyphilliticus), Sangra-dagua (C. urucurana), Pau-terra-de-folha-larga (Qualea grandiflora), Erva-de-Santa Maria (Chenopodium album), Amaro-leite (Operculina alata), Algodaozinho-do-campo (Cochlospermum regium), Cavalinha (Equisetum hiemale) andJaborandi (Piper aduncum), Pau-terra-de-folha-larga (Qualea grandiflora), Erva-de-Santa Maria (Chenopodium album), Amaro-leite (Operculina alata), Algodaozinho-do-campo (Cochlospermum regium), Cavalinha (Equisetum hiemale) andJaborandi (Piper aduncum)highlightedmorethan10RUV. The most important bodily systems in the number of reported plants were respiratory, digestive, circulatory and integumentary. The most versatile, useful plant systems were Copaiba (Copaiferalangsdorffii), Pe-de-perdiz (Crotonantisyphiliticus), Cavalinha (Equisetumhiemale), Rosemary (Rosmarinusofficinalis) and Fruita-de-lobo (Solanumpaniculatum).The practice of traditional medicine in Jatai reveals the link between the choice of plants and derived phylogenetic levels. Many referenced species are used medicinally in the Cerrado, including some that are part of the national health care system’s list, for the realization of monographs, which strengthen the knowledge of these traditional medicine practices in Goias.

Thismia panamensis : first record of Thismiaceae for the Brazilian Cerrado in Goiás state

We describe the first occurrence of the family Thismiaceae in the Brazilian Cerrado and a new record of Thismia panamensis (Standl.) Jonker for Brazil. We found the species in an urban fragment of semideciduous forest, municipality of Jatai, southeastern Goias state, Central Plateau Brazil. The record of this achlorophyllous mycoheterotrophic monocot is important, improving the knowledge of the flora of Cerrado domains and giving a better understand of the biogeography of Brazilian mycoheterotrophic angiosperms.
