Boraginales Juss. ex Bercht. & J.Presl in the Ecoregion Raso da Catarina, Bahia, Brazil

Abstract

Raso da Catarina is one of the eight Ecoregions recognized for the Caatinga biome. This work includes the taxonomic study of Boraginales Juss. . The species most commonly found were Cordia glabrata, Varronia globosa, V. leucocephala, Euploca procumbens, Heliotropium angiospermum and H. elongatum, associated with sandy soils. Cordia superba and C. trichotoma were found in moist environments, higher altitudes, clay or sandy-clayey soils. Euploca paradoxa was collected on the banks of the São Francisco River, and Varronia leucomalloides occurs in the hiperxerophytic Caatinga associated with rocky or sandy soils and in areas of contact between Caatinga and Cerrado, these species were more restricted in the area. Comments are made on the morphology and taxonomy, illustrations, and data on geographical distribution and phenology, besides a key for the taxa studied. . As espécies mais comumente encontradas foram Cordia glabrata, Varronia globosa, V. leucocephala, Euploca procumbens, Heliotropium angiospermum e H. elongatum, associadas aos solos arenosos. Cordia superba e C. trichotoma encontradas em ambientes mais úmidos, sobre altitudes mais elevadas, solos argilosos ou areno-argilosos. Euploca paradoxa coletada nas margens do rio São Francisco e, Varronia leucomalloides ocorrendo em Caatinga hiper-xeró fita, associada a solos pedregosos ou arenosos, e em áreas de contato entre Caatinga e Cerrado, foram às espécies mais restritas na área. São apresentados comentários sobre morfologia e taxonomia, ilustrac¸õ es, e dados sobre distribuic¸ão geográfica e fenologia, além de uma chave para os táxons estudados.

Bombacoideae, Byttnerioideae, Grewioideae and Helicterioideae (Malvaceae s.l.) in the Raso da Catarina Ecoregion, Bahia, Brazil

“…This study was based on fieldwork carried out from September 2013 to May 2015 during random walks exploring most of the study area. Fieldwork expeditions focused mainly conservation units (Figures 1, 2) within the southern part of the Ecoregion, in the state of Bahia: Environmental Protection Area Serra , Biological Station of , Ecological Station of Raso da Catarina -ESRC (09°33'13" to 09°54'30" S and 38°29'20" to 38°44'00" W), State Park of , and PRNH Farm Flor de Lis (10°50'14.1" to 10°50'26.4" S and 38°31'46.4" to 38°31'34.7" W) (Vieira et al 2015).…”

Bignoniaceae in the Raso da Catarina Ecoregion, Bahia, Brazil

“…The expeditions concentrated in the conservation units ( Figure 1) located in the southern part of the Ecoregion, portion Bahia; EPA Serra Branca (09°53'15.5" to 09°44'34.6" S and 38°49'36.1" to 38°52'20.4" W); Biological Station of Canudos-BSC (09°55'58.6" to 09°58'25.2" S and 38°57'32.2" to 39° 01'38.5" W); Ecological Station Raso da Catarina-ESRC (09°33'13" to 09°54'30" S and 38°29'20" to 38°44'00" W); State Park of Canudos-SPC (09°56 '19.7" to 09°54'32.4" S and 39°06'13.3" to 39° 04'20.5" W) and RPPN Farm Flor de Lis (10°50'14.1" to 10° 50'26.4" S and 38°31'46.4" to 38°31'34.7" W) (Vieira et al 2015).…”

“…In addition, it also has the lowest number of conservation units and is one of the least protected in Brazil (Leal et al 2005). The most recent contributions about flora of Raso da Catarina Ecoregion are generally local floristic surveys of groups in specific areas, such as the works conducted by Melo & Andrade (2007); Melo et al (2010); Brito (2012); Lopes (2012); Dourado et al (2013); Varjão et al (2013); Vieira et al (2013); ; Lima & Conceição (2016); Santos et al (2016) and; Correia & Conceição (2017a, 2017b, with few floristic surveys covering all areas of the Ecoregion, such as ; Lima (2015); Vieira et al (2015); Amorim & Bautista (2016) and; Santos (2016).…”

Phytochemical screening of Cordia glabrata (MART.) A.DC. extracts and its potential antioxidant, photoprotective, antimicrobial and antiviral activities

“…The species Cordia glabrata is a plant that belongs to the genus Cordia Linnaeus and the Boraginaceae Family, which is distributed from Central America to the central region of Argentina (IPNI, 1845;Vieira et al, 2015).…”

“…The species Cordia glabrata (Mart.) A.DC., popularly known as "louro-branco", "claraíba", "louro-de-matogrosso" and "peteribi", occurring from the Piauí to the Northeast of Mato Grosso do Sul state, mostly concentrated in the Pantanal and Cerrado (Brazilian Savannah) regions of Mato Grosso -Brazil (Vieira et al, 2015;Moulin et al, 2016), there are still no reports on the species phytochemical profile, and its possible biological activities.…”
