Pimpinella ibradiensis, an unusual new species found in the Toka Yayla (İbradı, Antalya) in southern Anatolia, is described and illustrated. Site conditions, synecology and conservation status of P. ibradiensis are considered. In light of the comparison with the other closely related four species, namely P. nephrophylla, P. flabellifolia, P. sintenisii and P. paucidentata, its similarity within the genus are discussed. P. ibradiensis is easly distinguished from its relatives by its white petals, presence of bracts and bracteoles, larger fruits (4–5.5 × 1–2 mm), and having serrulate basal leaves with 60–95 strongly cartilaginous teeth along margins. The geographical distribution of P. ibradiensis and closely related species are mapped and the identification key of those species is updated.

ABSTRACT Taxonomic and floristic studies in the state of Rio de Janeiro allowed the rediscovery of Miconia gigantea, an endemic species to the Atlantic Forest, until recently known only from the type specimen, collected over 100 years by A.F.M. Glaziou. We present an amended and detailed description of M. gigantea, providing characteristics of the flowers, fruits and seeds, in addition to illustrations, comments about taxonomic affinities with closely related species, the presently known distribution together with new occurrence records, and the conservation status.

A floristic survey of the Cactaceae family was carried out in the municipality of Santa Maria, Brazil, which is localized in the central region of Rio Grande do Sul state. The study was conducted between August 2017 and November 2018, during which time 14 species were recorded. Five species are on the endangered species list of Rio Grande do Sul. The threatened species are Echinopsis oxygona (Link) Zucc. Ex. Pfeiff. Otto, Parodia horstii (F. Ritter) N.P. Taylor, Parodia glaucina (F. Ritter), Hofacker M. Machado, Parodia linkii (Lehm.), R. Kiesling, and Parodia ottonis (Lehm.) N. P. Taylor. This paper presents a complete list of the species with reference to conservation status.

Schinus pampeana is a new species from Brazilian Pampa. The new species was tentatively included in Schinus sect. Terebinthifolia, and is morphologically most similar to Schinus lentiscifolia and S. weinmanniifolia. We present here a detailed morphological description, a geographical distribution map, IUCN conservation status assessment, ecological data, photographs, and a table of diagnostic characters of S. pampeana and the most similar species. Schinus pampeana increases the total number of Schinus to about 49 species, of which eleven are recorded in Brazil.

During a search for populations of wild common bean, namely south of the Central Valley of Costa Rica, a new bean species, Phaseolus albicarminus, has been found on the slope of a mountainous range named Cerros Llano Bonito in the western part of Talamanca range, where it appears to be endemic. Its main morphological features are: short pseudoracemes with four small deltoid primary bracts, small early caducous deltoid bracteoles, calyx lobes reduced to two lips, white wings contrasting with carmine purple inner face of standard, and smoothly curved 3–4 seeded pods with prow-shaped beak. The differences with apparently closely related species, P. hygrophilus and P. angucianae, are: in primary bracts (orbicular versus oval acuminate), larger bracteoles (cordate versus rounded), inner face of standard (pale pink to white versus purple), lower calyx lobes (rounded versus triangular), and pod dorsal suture (straight versus sigmoid), respectively. The fact that to date only three populations of P. albicarminus are known from the same small area of Costa Rica, calls for monitoring its conservation status. This new species is tentatively assigned to the section Brevilegumeni which seems well represented in Costa Rica (with five out of six taxa).
