“…Fruit-set under natural conditions was low in C. leucocephala, and in many other populations no fruits were registered at all (I.C. Machado personal observation, Andrade- Lima 1989, Taroda and Gibbs 1986b, Melo and Sales 2005, Melo and Andrade 2007. This could be due to two reasons: the low pollen viability (60%) and the foraging behavior of the specialist pollinator, which may induce geitonogamy, as discussed below.…”

In this study we compare the reproductive biology of Cordia globosa and C. leucocephala (Cordiaceae, Boraginales; formerly referred to Boraginaceae) to understand the functioning of the floral morphs and the relations with their effective pollinators. The species are synchronopatric, distylic, and self-incompatible. Though they share melittophilous traits, the main visitor and pollinator of C. globosa was the generalist and exotic bee Apis mellifera, while the only one of C. leucocephala was the oligoletic bee Ceblurgus longipalpis. These two latter species are restricted to the Caatinga of NE Brazil, contrasting with the wide distribution of Cordia globosa. While the fruit-set for C. globosa was high, independently if the pollen donor/stigma receptor was a pin (long-styled) or thrum (short-styled) individual, in C. leucocephala the fruit-set was low and occurred only when a thrum individual was the pollen donor. This raises the possibility of this species moving towards dioecy. The high natural fruit-set of C. globosa confirms the generalist bee as its effective pollinator. The low fruit-set after manual crosses in C. leucocephala may be due to low pollen viability. Additionally, the low natural fruit-set (two times lower than after crosses) may be related with the foraging behavior of the specialist pollinator.

“…Identifications were made based mainly on specialized bibliography (e.g., Johnston 1928, Taroda & Gibbs 1986a, 1986b, Diane et al 2002, Melo & Sales 2004, Melo & Andrade 2007, Miller & Gottschling 2007, Freitas et al 2008, Melo & Semir 2008, Melo et al 2009aand Melo & Semir 2010, protologues, photos of type collections and consulting of the collections in the visited herbaria. For taxonomic descriptions, the terminologies proposed by Radford et al (1974), Ribeiro et al (1999) and Harris & Harris (2001) were adopted.…”

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.

ResumoEste trabalho consiste no levantamento florístico da família Boraginaceae na APA Serra Branca/Raso da Catarina, localizada no município de Jeremoabo, Bahia. AbstractThis work consists of a floristic survey of Boraginaceae in APA Serra Branca/Raso da Catarina, located in Jeremoabo, Bahia, Brazil. We analyzed specimens collected between August 2009 and June 2011 and collections deposited in the ALCB, HRB and HUEFS herbaria. Four genera and ten species of Boraginaceae were found: Cordia rufescens A.DC., C. trichotoma (Vell.) Arráb. ex Steud., C. glabrata (Mart.) A.DC., Heliotropium angiospermum Murray, H. elongatum (Lehm.) I.M.Johnst., Tournefortia rubicunda Salzm. ex DC., T. salzmannii DC., Varronia curassavica Jacq., V. globosa Jacq. e V. leucocephala (Moric.) J.S.Mill. Keys for identification of genera and species, descriptions, illustrations and comments about geographic distribution and phenology of the species are presented.
