          Abstract

          Raso da Catarina is one of the eight Ecoregions recognized for the Caatinga biome. This work includes the taxonomic study of Boraginales Juss. ex Bercht. & J.Presl in the Ecoregion Raso da Catarina, Bahia state, Brazil. The samples analyzed were collected from March 2009 to July 2013. The analyses were supplemented with dried collections kept in the herbaria: ALCB, IPA, HRB, HST, HTSA, HUEFS, HVASF, PEUFR and UFP. Two families, five genera and 16 species were recorded. The Cordiaceae family was represented by genera Cordia L. [C. glabrata (Mart.) A.DC., C. rufescens A.DC., C. superba Cham. and C. trichotoma (Vell.) Arráb. exSteud.] and Varronia P.Browne [V. curassavica Jacq., V. globosa Jacq., V. leucocephala (Moric.) J.S.Mill. and V. leucomalloides (Taroda) J.S.Mill.] and Heliotropiaceae with the genera Euploca Nutt. [E. paradoxa(Mart.) J.I.M.Melo & Semir and E. procumbens (Mill.) Diane & Hilger], Heliotropium L. [H. angiospermum Murray, H. elongatum (Lehm.) I.M.Johnst. and H. indicum L.] and Myriopus Small [M. candidulus (Miers) Feuillet, M. rubicundus (Salzm. ex DC.) Luebert and M. salzmannii (DC.) Diane & Hilger]. 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. trichotomawere 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.

Diane & Hilger]. 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-xerófita, associada a solos pedregosos ou arenosos, e em áreas de contato entre Caatinga e Cerrado, foram ès espécies mais restritas na área. São apresentados comentários sobre morfologia e taxonomia, ilustrações, e dados sobre distribuição geográfica e fenologia, além de uma chave para os táxons estudados.

            Phylogeny of Lamiidae.

            The Lamiidae, a clade composed of approximately 15% of all flowering plants, consists of five orders: Boraginales, Gentianales, Garryales, Lamiales, and Solanales; and four families unplaced in an order: Icacinaceae, Metteniusiaceae, Oncothecaceae, and Vahliaceae. Our understanding of the phylogenetic relationships of Lamiidae has improved significantly in recent years, however, relationships among the orders and unplaced families of the clade remain partly unresolved. Here, we present a phylogenetic analysis of the Lamiidae based on an expanded sampling, including all families together, for the first time, in a single phylogenetic analyses.
