Stigmaphyllon caatingicola is described and illustrated. We also provide a distribution map, and comments on species distributions, conservation and taxonomy. This species is distinguished from Stigmaphyllon urenifolium by its deciduous leaves when flowering, lamina membranaceous, entire to apically trilobed, abaxially tomentose, with hairs deciduous in patches, one latero-anterior petal with reddish macula, sepals with darkish hairs, styles glabrous, stigma foliolate, and samaroid mericarps densely sericeous, with a dorsal wing horizontally orientated.
Thismia prataensis (Thismiaceae), a New Species from the Brazilian Atlantic Rain Forest
A new Thismiaceae species, Thismia prataensis, from the Brazilian Atlantic Rain Forest is described and illustrated. This species was found growing in the "Serra da Prata" mountain range, Morretes, Paraná State, southeastern Brazil, and is distinguished from the other species in the genus by the presence of six bracts in two whorls, free interstaminal lobes, six depressions that surround the throat, double longitudinal lamellae on the outside of the floral tube and stigma with papillose surface. This is the most southerly record for the group in the Neotropical region. A key of the Thismia species inhabiting the Atlantic Rain Forest is also provided.
Morphological description and new record of Panaeolus acuminatus (Agaricales) in Brazil
Panaeolus acuminatus is described and illustrated based on fresh specimens collected from Northeast Brazil. This is the second known report of this species for the country, since it was already reported in 1930 by Rick. The species is characterized by the acuminate, pileus with hygrophanous surface, basidiospores measuring 11.5-16 × 5.5-11 µm and slender, non-capitate cheilocystidia. A full description accompanies photographs, line drawings and taxonomic discussion.
This paper provides descriptions and illustrations of a new species, Barjonia furlanii (Asclepiadoideae, Apocynaceae), from Serra da Canastra National Park, in the state of Minas Gerais, Brazil. This species is similar to B. laxa, especially in its frondose thyreoid inflorescence, compound corona, and linear leaves. It is, however, distinguished from B. laxa by internodes (up to 4 cm long), peduncles (4.2–5mm long) and much shorter pedicels (4–6 mm long), erect leaves, attenuated at the base, and partial inflorescences that alternate with 2–4 flowers. B. furlanii is proposed for Endangered status under IUCN guidelines (EN B2abiii), and a key to all Barjonia species is included in this study.

Original Research Article This work is a contribution to a better knowledge of the species of the genus Prosopis. It proposes specifically, to highlight the similarities and dissimilarities between Prosopis juliflora and P. chilensis. To achieve the results, observations and measurements were made on the different organs of the species. The comparison of the data obtained shows that the discriminating features are the spines which are more frequent on the branches of P. chilensis and rare on those of Prosopis juliflora. The distinguishing traits are related to the inflorescence of P. juliflora which is longer and denser than that of Prosopis chilensis. The top of the pod (beak) is more tapered in P. juliflora. This work allowed the identification of the two species of the genus Prosopis.
Phyllanthaceae in the Atlantic Forest of northeastern Brazil
Biota Neotropica, 2022
The taxonomy of Phyllanthaceae Martinov in the Atlantic Forest of northeastern Brazil was updated through the analysis of approximately 200 specimens deposited in regional herbaria as well as field observations. Thirty-five species were recorded, belonging to seven genera:
Preliminary Study of Some Vegetation Types of the Pantanal, Mato Grosso, Brazil
Brittonia, 1982
Pantanal is the region on the Brazil-Bolivia frontier in the Paraguay river basin, that is predominantly, but not exclusively covered by various types of swamp vegetation. The vegetation of the area was studied by extensive collecting and through measuring trees on five one-hectare plots of cerrado and semi-deciduous forest. The region consists of various types of swamp, gallery forest, lake margin scrub forest, semi-deciduous forest, and several forms of cerrado and savanna. The vegetation is made up of species derived from the cerrado of Central Brazil, the Chaco and Amazonia. It also includes many widespread but few endemic species. Little vegetation remains undisturbed due to the influence of cattle, fire and man. Good examples of the various vegetation formations can still be found and are in urgent need of conservation.
Magnoliophyta, restinga vegetation, state of Ceará, Brazil
Sandy coastal plain (Restinga) vegetation is composed of the plant communities that grow on Quaternary Neosols along the entire Brazilian coast. Ceará state has a coastal extension of 578 km and lies totally within the semi-arid zone of northeastern Brazil. Here we present a checklist of the phanerogamic species found along the coast of Ceará that was compiled from surveys and collections found at the EAC herbarium (Fortaleza, Ceará). A total of 391 species distributed among 208 genera and 41 families were identified. The families with the greatest numbers of species were Fabaceae senso latu (130 species), Cyperaceae (51), Poaceae (47), Rubiaceae (27), Euphorbiaceae (19), Asteraceae (13), Bignoniaceae (11) and Malvaceae (12), representing over 78.77% of the species collected.
