Caesalpinioideae is the second largest subfamily of legumes (Leguminosae) with ca. 4680 species and 163 genera. It an ecologically economically important group formed mostly woody perennials that range from large canopy emergent trees to functionally herbaceous geoxyles, lianas shrubs, which has a global distribution, occurring on every continent except Antarctica. Following recent re-circumscription 15 genera as presented in Advances Legume Systematics 14, Part 1, using basis phylogenomic...
The ultrastructure of the pillar cells in gill lamellae freshwater shrimp Macrobrachium olfersii was examined to evaluate routes salt and water movement across epithelium into hemolymph. Alterations were morphometrically quantified maintained fresh (FW, <0.5{permill} salinity) after acclimation saline media (21{permill} or 28{permill} salinity). tissue interface between hemolymph external medium consists exclusively thin apical flange regions cells, upper membrane which is highly amplified...
Senna sect. Chamaefistula (DC. ex Collad.) H. S. Irwin & Barneby ser. Spinescentes is restricted to the Neotropical region and has species distributed predominantly in lowland forest of Amazonia. These are morphologically distinguished by their scandent or viny habit, stipular thorns, laterally compressed fruits with seeds parallel fruit valves. Previous taxonomic treatments have recognized only two formally described one variety; nevertheless, they served as a baseline for more...
Abstract— Senna (Leguminosae, Cassiinae) is a speciose genus widely distributed throughout tropical and subtropical regions of the world. During taxonomic studies sect. Chamaefistula ser. Bacillares , new endemic endangered species from Atlantic Forest Bahia, Brazil was discovered. The species, bahiensis, compared with its morphologically similar gardneri including x-ray analysis comparison their leaflet venation patterns. use high resolution digital images provided decisive information,...
Senna ser. Bacillares (Leguminosae, Cassieae) is the largest of American series, with approximately 50 species. Several taxa are still poorly known or problematic delimitation. Based on extensive fieldwork and collection‐based research for our ongoing taxonomic studies , we identified two new species which here describe as S. dryadica franciscana . In addition, recognize gloriosa a morphologically ecologically distinct species, rather than variety splendida The illustrated described,...
Stryphnodendron is a Neotropical genus of Fabaceae (Caesalpinioideae, mimosoid clade), comprising 36 taxa occurring from Nicaragua to Southern Brazil, most them found and endemic in being especially frequent savannas (Cerrado) the Amazon Forest. This synopsis presents designation 16 lectotypes, eight new synonyms, combination with nomenclatural status change, species’ reestablishment, two doubtful names three excluded species. We also present nine species, which are described illustrated....
The new species Eugenia stenocarpa Valdemarin & A.Maruy. is described and illustrated. It nested within sect. Speciosae but distinguished from other in the section by combination of its sparsely puberulent glabrescent young twigs, revolute leaf margin with a thickened yellow edge, flowers pubescent hypanthium, remarkable cylindrical fruits. Images specimen situ dried material are provided, as provisional conservation assessment discussion morphological similarities between species.
Abstract Senna sect. Chamaefistula ser. Coriaceae is restricted to Brazil and predominantly distributed in savanna habitat. The species are morphologically characterized by their shrub or treelet habit, usually reniform stipules, extrafloral nectaries positioned on the middle distal part of petiole, zygomorphic corolla laterally compressed fruits with seeds parallel fruit valves. Previous taxonomic studies have recognized only three one variety, nevertheless, they provided groundwork for a...
Copaifera L. is a tropical genus with its highest diversity in the New World, renowned for “copaiba oil” extracted from trunk of many species, which has wide applications traditional medicine and pharmachemical industry. Despite relatively recent revisions, still deemed complex species difficult to recognize due often overlapping circumscriptions. A crucial step delimitation correct application names analysis types. Advances digitization biological collections bibliographical material have...
Abstract— Chamaecrista is one of the largest genera Leguminosae, subfamily Caesalpinioideae. Traditionally, it has been divided into six sections, which sect. Absus largest, with 31 series. ser. Setosae comprises nine species. setosa most widely distributed species, comprising four varieties, distinguished by type and distribution glandular trichomes, leaflet venation. Given importance venation in delimitation taxa, here we performed a study architecture all species series more detailed...
Abstract— During a taxonomic treatment of Stryphnodendron (Leguminosae, Caesalpinioideae, mimosoid clade) for the Brazilian Flora 2020 Project, one new presumably critically endangered species from Atlantic Forest domain was found, and is so far only known to western Espírito Santo state. flavotomentosum described illustrated, information on its distribution, habitat, phenology, preliminary conservation status provided. Additionally, an identification key rainforests presented.

Copaifera L. is a pantropical genus with great diversity in the Cerrado. Fieldwork western S&atilde;o Paulo revealed first record of C. malmei Harms this state, and only second time that species has been found Southeast Region Brazil. Additional analyses related species, marginata Benth. same rare pattern distribution region. We provide morphological descriptions, comments on geographical distribution, assessment conservation status, phenology, an identification key to Cerrado southeastern
Pombalia Vand. (Violaceae) is represented in the Cerrado by a well-supported monophyletic group of species known as lanata complex, characterised some unique vegetative and reproductive features within genus. This includes six – cristalina, P. insignis, lanata, poaya, strigoides velutina first two which are new to science. shows widest geographical distribution throughout Central Brazilian Plateau Espinhaço Range Minas Gerais state, with disjunction Misiones Province, Argentina.
