We describe and illustrate two new species of Jatropha from Bahia State, Brazil: Jatropha longibracteata and Jatropha paganuccii. The two new species occur on limestone outcrops in seasonally dry tropical forests. We also provide a distribution map and IUCN conservation status, as well as morphological comparisons with the closely related species J. calcarea, J. martiusii, and J. palmatipartita.

A striking new species of Begonia, B. joshii, is described from Amazonas Region, Peru. The new species is unusual among the South American members of the genus both in its combination of tuberous habit with peltate leaves and in living in a seasonally dry tropical forest environment. A phylogeny of this and closely related species is presented, and its sectional affiliation and IUCN conservation status are discussed. A key to the peltate Peruvian species of Begonia is provided.

Morphological revision and phylogenetic analyses, based on nrITS and nrLSU, of specimens previously considered to be member of the “Inonotus linteus” species complex from in South America reveal a new species of Tropicoporus, here named T. drechsleri. It is a parasitic polypore restricted to the seasonally dry tropical forests of subtropical South America. Illustrations, taxonomic analyses and a discussion are presented, and a key to the Tropicoporus species in the Neotropics is provided.

A New Species

Ten years after the last description of a new species of Aspilia from Brazil, a new species of Brazilian Aspilia (Heliantheae, Asteraceae) is here described as A. pseudocalea, a species endemic to the State of Goiás, Brazil. This new species is recognized by its herbaceous habit, linear leaves, and a prominent glabrous, stramineous scar on the base of the cypsela that extends to near the middle of the fruit body. It is closely related to A. prostrata, but differs by the leaf shape, involucre size and number of series of involucral bracts, and geographical distribution. Illustrations, comments, distribution map, and conservation status are provided for the new species. Additionally, a diagnostic key to closely related species is provided.

A New Species

Ditaxis is a Neotropical genus with approximately 50 species, most of them in seasonally dry tropical forests of Brazil, Central America and the Antilles. The Brazilian Caatinga, the largest area of SDTF in South America, harbors three endemic species of Ditaxis, including the new Ditaxis grazielae, hereby described and illustrated. The new species is known from a few localities in the state of Bahia. We provide an identification key for the species occurring in the Caatinga, as well as comments on habitat, distribution and phenology. We also present amended descriptions and typifications for Ditaxis desertorum and D. malpighiacea, and propose D. gardneri as synonym of D. desertorum.

AbstractWe evaluated the effect of ENSO 2015/16 on the water relations of eight tree species in seasonally dry tropical forests of the Yucatan Peninsula, Mexico. The functional traits: wood density, relative water content in wood, xylem water potential and specific leaf area were recorded during the rainy season and compared in three consecutive years: 2015 (pre-ENSO conditions), 2016 (ENSO conditions) and 2017 (post-ENSO conditions). We analyzed tree size on the capacity to respond to water deficit, considering young and mature trees, and if this response is distinctive in species with different leaf patterns in seasonally dry tropical forests distributed along a precipitation gradient (700–1200 mm year−1). These traits showed a strong decrease in all species in response to water stress in 2016, mainly in the driest site. Deciduous species had lower wood density, higher predawn water potential and higher specific leaf area than evergreen species. In all cases, mature trees were more tolerant to drought. In the driest site, there was a significant reduction in water status, regardless of their leaf phenology, indicating that seasonally dry tropical forests are highly vulnerable to ENSO. Vulnerability of deciduous species is intensified in the driest areas and in the youngest trees.

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.

AbstractThe Aschistodesmini from the Solomon Island are reviewed. Besides clarifying notes on the status of the type and closely related species of Aschistodesmus, descriptive notes and illustrations of the gonopods of the Solomon species of this genus, particularly of those published by Chamberlin, 1920, under the generic name of Solomonosoma, are given. Two new species, A. spatulifer and A. tridentifer are described, and a key to the species is provided. From Rennell Island Dorcadogonus modestus gen. n., sp. n. is described.
