Abstract Malvoideae is the largest subfamily of Malvaceae, including 110 genera and 1,730 species distributed predominantly in tropical regions, with a few representatives in temperate regions. In Brazil, the subfamily occurs throughout the country and all phytogeographic domains. The floristic survey of Malvoideae in the Environmental Protection Area Serra Branca included analysis of 43 specimens collected from August 2011 to February 2013. The analysis were supplemented with dried collections from the following herbaria: ALCB, HUEFS and MAC. Six genera and sixteen species were recorded. Sida L. was the most representative genus with five species [S. angustissima A.St.-Hil., S. castanocarpa Krapov., S. cordifolia L., S. galheirensis Ulbr., S. linifolia Cav. and S. spinosa L.], followed by Pavonia Cav. with three species [P. blanchetiana Miq., P. cancellata (L.) Cav. and P. glazioviana Gürke], Sidastrum Baker with three species [S. micranthum (A.St.-Hil.) Fryxell, S. multiflorum (Jacq.) Fryxell and S. paniculatum (L.) Fryxell] and Herissantia Medik. with two species [H. crispa (L.) Brizicky and H. tiubae (K.Schum .) Brizicky]. The remainging genera were represented by one species each: Pseudabutilon virgatum (Cav.) Fryxell and Malvastrum tomentosum (L.) S.R.Hill. The majority of the species recorded in the area have a Neotropical distribution, and six species are endemic to Brazil, among which the species Herissantia tiubae, Sida galheirensis, Pavonia blanchetiana and Pavonia glazioviana are endemic to the Northeast Region, the latter two species occurring exclusively in the Caatinga biome. The taxonomic treatment includes a key for the identification, descriptions, illustrations, photos, data of the geographical distribution, economic potential and reproductive phenology and comments about the species.

Abstract: Leguminosae includes six subfamilies, where the traditionally recognised subfamily Mimosoideae was accepted as a distinct clade included within the recircumscribed subfamily Caesalpinioideae, called informally as Mimosoid clade. The representatives of the tribes Acacieae and Ingeae can be differentiated principally in terms of the patterns of their stamens, being free in Acacieae and monadelphous in Ingeae. The floristic survey of Acacieae and Ingeae in the Environmental Protection Area Serra Branca included analysis of specimens collected from June 2011 to September 2012. The analyses were supplemented with dried collections from the following herbaria: ALCB, HRB and HUEFS. Ten species were cataloged, distributed among four genera of Ingeae: Calliandra Benth. (1 sp.), Chloroleucon (Benth.) Britton & Rose ex Record (1 sp.), Enterolobium Mart. (1 sp.), Pithecellobium Mart. (1 sp.); and one genus of Acacieae: Senegalia Raf. (6 spp.). The most representative species were Calliandra aeschynomenoides Benth. associated with sandy and stony soils and Chloroleucon foliolosum (Benth.) G.P.Lewis and Senegalia bahiensis (Benth.) Seigler & Ebinger growing on sandy-clay soils. The taxonomic treatment includes a key for the identification, descriptions, illustrations, photos, data of the geographical distribution phenological data and comments about the species.

Abstract The genus Pentacalia belongs to the tribe Senecioneae. It is represented by approximately 160 species predominantly distributed in the Andes. Species of Pentacalia are characterized by having a scandent habit, usually alternate leaves, axillary or terminal capitulescence, homogamous or heterogamous capitula, commonly yellow ray-florets, yellowish, creamy, or whitish disc-florets, sagittate to caudate anther-bases, and cypselae with five to ten ribs. The aim of the present study was to perform a taxonomic treatment of Pentacalia in Brazil, where it is represented by two species, P. desiderabilis and P. tropicalis, from the Atlantic Forest Domain. Detailed descriptions, taxonomic discussions, geographical distributions, an identification key, illustrations and a new record of P. tropicalis for the Northeast Region are presented. Moreover, three names (Senecio desiderabilis, S. ellipticus, and S. tropicalis) are lectotypified.

Abstract Objectives This study was conducted to analyze the trends in colorectal cancer (CRC) incidence and mortality in the city of Aracaju, Sergipe State, Brazil, between 1996 and 2015 with Joinpoint Regression Program 4.7.0.0 and to identify the geographical distribution of CRC in the municipality. Results A total of 1322 cases of CRC and 467 CRC-related deaths during the study period were included. In total, 40% of the incident cases and 43% of the deaths occurred in men, while 60% of the incident cases and 57% of the deaths occurred in women. Males who were 20 to 44 years old had the most significant trend in growth. Among women, those in the group aged 45 to 64 years had the highest observed annual percent change (APC). In both sexes, mortality was stable. Regarding the geographic distribution, there were constant hotspots in the northeast region of the municipality. This study showed a significant increase in incidence, mainly in young men between 20 and 44 years of age, but stable mortality in Aracaju.

Othonna L. (Asteraceae: Senecioneae: Othonninae) is a genus of some 120 species concentrated in the Greater Cape Floristic Region (GCFR) of South Africa, with a few species extending into southern Namibia, Angola, and Zimbabwe. The South African species of Othonna were last revised more than a century ago, and many species, particularly from the southern African winter rainfall region, remain poorly understood. This study focused on the geophytic species comprising the O. bulbosa group, distinguished by their tuberous rootstock and annual, leafy, aerial stems. A comprehensive taxonomic treatment is presented, including descriptions, complete nomenclature and typification, illustrations, and geographical distribution. Twenty-five species are recognized, of which four are newly described (O. lilacina Magoswana & J. C. Manning, O. nigromontana Magoswana & J. C. Manning, O. revoluta Magoswana & J. C. Manning, and O. sinuata Magoswana & J. C. Manning), and 18 names are reduced to synonymy. The species differ in habit, shape and incision of foliage, capitulum type (radiate vs. disciform), number of involucral bracts, pappus length, and cypselae (myxogenic vs. nonmyxogenic). We place the species into four morphologically diagnosable series (series Heterophyllae Magoswana & J. C. Manning, series Disciformes Magoswana & J. C. Manning, series Perfoliatae Magoswana & J. C. Manning, and series Undulosae Magoswana & J. C. Manning) based on habit and capitulum type.
