This paper provides a taxonomic assessment and distribution details of the species of the genus Ludwigia L. (Onagraceae) for the Paraíba State, Northeastern Brazil. Six species were found: L. erecta (L.) H.Hara, L. helminthorrhiza (Mart.) H.Hara, L. hyssopifolia (G.Don) Exell, L. leptocarpa (Nutt.) H.Hara, L. nervosa (Poir.) H.Hara and L. octovalvis (Jacq.) P.H.Raven. Ludwigia nervosa was recorded for the first time in the studied area. Our taxonomic treatment comprises an identification key to the species. For each species, description, illustrations, taxonomic comments, flowering and fruiting data, geographic distribution map, and the conservation status for the studied area are provided. Among the recorded species, three were classified as “Near Threatened”, two as “Vulnerable” and one as “Critically Endangered”.

Taxonomic Treatment

Anupdated circumscription and a taxonomic treatment of Chamaecrista sect. Absus subsect. Absus ser. Rigidulae is presented based on the results of previous phylogeny study where the series has emerged as monophyletic with exclusion of two species (C. brachyblepharis and C.ciliolata) and inclusion of two others species (C. botryoides and Ch. sincorana) in its circumscription. This revision resulted from consulting the specialized literature, analyzing of about 1400 collections from national and foreign herbaria. In this new circumscription, the series becomes the largest series of the genus with 32 species endemics to Brazil and distributed mainly in the Brazilian Central Plateau. Two new records in Brazilian states were reported, one to Bahia (Ch. feliciana) and two to Minas Gerais (Ch. benthamiana, Ch. rupestrium); an identification key of the species, morphologic descriptions, notes on taxonomy and geographic distribution of the taxa, conservation status, as well as illustrations and images of diagnostic characters are presented. In addition, the species typification remains updated with all categories indicated first with their respective barcodes.

The taxonomic treatment of Hirtella (Chrysobalanaceae) from Bahia State, Brazil, is presented. We recognize 14 species; H. bicornis is recorded for the first time in the state and H. prancei was originally described from this study. The treatment includes an identification key to species, descriptions and comments on taxa, as well as illustrations and geographic distribution maps of species in Bahia. An identification key to the genera of Chrysobalanaceae in the state is also provided.

The casque-headed frog Aparasphenodon brunoi is recorded for the first time in the municipalities of Ilhéus and Igrapiúna, southern region of Bahia state, northeastern Brazil. The new record of A. brunoi in the municipality of Igrapiúna, represents an increase of its known geographic distribution of approximately 150 km north from its nearest locality (airline), in municipality of Una, state of Bahia, representing now the northernmost known record for this species.

A New Species

The species of Centris of the hyptidis group are revised. The group, composed by C. hyptidis Ducke, C. hyptidoides Roig-Alsina, and C. thelyopsis n. sp., exhibits unique morphological characters within the genus, like foreand midtrochanters with a laminar expansion at the base, and elaiospathes strongly modified. An updated catalog, and floral and distributional records are provided for each species, as well as an identification key and a distribution map. The male of C. hyptidoides is described for the first time and a modern diagnosis for C. hyptidis is presented. A new species, C. thelyopsis n. sp., is described from Goiás State, in central Brazil. It can be easily distinguished from the two previously known species by its predominant orange pilosity, including that of the hind legs and metasoma.

Abstract: A taxonomic treatment of Dalechampia species found in the Brazilian Amazon is presented. The study was based on an analysis of herbarium material (including historical and type collections), specimens collected in the field, and literature. Twenty-three species, distributed in five sections, are recognized. Dalechampia hastata is endemic to the Brazilian Amazon. Among the species surveyed, thirteen species are considered to be Least Concern (LC), and not currently at risk of extinction. Six species (D. attenuistylus, D. brownsbergensis, D. fragrans, D. hastata, D. megacarpa and D. olympiana) are Endangered (EN), three species (D. gentryi, D. heterobractea and D. tenuiramea) are Near Threatened (NT), and D. liesneri is listed with Deficient Data (DD). If we consider the occurrence only in Brazil of three species , the taxa can be designated as Vulnerable (VU). Dalechampia micrantha and D. parvibracteata are lectotypified. The lectotype of D. cissifolia, D. juruana, and D. pernambucensis is clarified. New occurrences are reported for some countries. An identification key, descriptions, taxonomic comments, illustrations, the conservation status, phenological data, and geographic distribution maps are provided.

Paepalanthus cordatus is an endangered species described from a single collection which lacks fully developed inflorescences and flowers. Despite the absence of these characters, the species was unambiguously placed in P. sect. Diphyomene, one of the few groups of Paepalanthus with dimerous flowers and which is mainly distributed in central Brazil. In this manuscript, I provide a full description of the species, detailing and illustrating the fully developed inflorescences and flowers for the first time. The spherical umbel-shaped inflorescence is composed of sets of capitula bearing dimerous flowers; the pistillate flowers have dolabriform sepals and bifid stigmatic branches; the staminate ones have an elongated fleshy anthophore. These characters fully match the current circumscription of P. sect. Diphyomene. Based on the specimens recently collected and additional data, the new conservation status for the species is Endangered instead of Critically Endangered, as previously assessed. I also clarify the inadvertent lectotype selection and previous interpretations of the type specimens. Comments on the species distribution, morphology, and ecology, as well as a geographic distribution map, photos, and a detailed illustration are also provided.

Magnolia lozanoi is rediscovered 26 years after being collected for the first time. Herbarium specimens were collected by Al Gentry in 1993 and formally described by Antonio Vázquez and Ernesto Castro in 2012. This species is known only from El Quimi Biological Reserve in the province of Morona-Santiago, southeastern Ecuador. An emended description, distribution map and the first photographs of this species are provided. Additionally, its relationships with other species are discussed. Its conservation status is proposed as critically endangered (CR) according to IUCN criteria.
