“…2). The Bowdichia clade can be diagnosed by apomorphies of: lower petals (wings and keel) subequal and symmetric (character 13: state 2; Appendix 2); lateral petals (wings) without sculpturing (15:1); staminal filaments free to the base (20:2); compressed samaroid fruit (24:2), although some species with nut-like fruits occur in both Leptolobium and Diplotropis (Lima, 1985;Rodrigues & Tozzi, 2012); bracts persistent at fruiting (25:1), but with a reversal to caducous in Leptolobium; and bulbous radicle (28:1). The tufts of minute colleter-like glands (cf.…”

The Neotropical Bowdichia clade (Leguminosae: Papilionoideae) comprises four genera, Bowdichia, Diplotropis, Guianodendron, and Leptolobium, which are sister to the core Genistoid clade. Bowdichia and Diplotropis at one time were treated as a single genus, whereas Guianodendron and Leptolobium have been synonymized with the distantly related Dalbergioid genus Acosmium because of shared radial floral symmetry. We combined and analysed morphological and molecular data including the nuclear ribosomal internal transcribed spacers (ITS; including ITS1/5.8S/ITS2) and two chloroplast DNA (matK, trnL intron) regions in order to evaluate the monophyly of each genus and the Bowdichia clade. A combined parsimony analysis strongly supported the monophyly of Bowdichia, the paraphyly of Diplotropis, and the independent evolution of radial floral symmetry in Guianodendron and Leptolobium. Leptolobium is sister to Bowdichia and Guianodendron is nested within Diplotropis s.l. Diplotropis is here recircumscribed as to encompass the monophyletic Diplotropis sect. Diplotropis and it is suggested that D. sect. Racemosae deserves segregation into a new genus. Radial floral symmetry has been overemphasised in previous classifications by taxonomists who did not recognize its evolutionary lability. This has resulted in nonmonophyletic circumscriptions of genera such as Acosmium.

“…We sampled a richness constituted by 17 species, Leptolobium elegans was the main taxon that contributes the most to the structure of this savanna, with more than half of the relative L. elegans is a heliophytic species that inhabits different physiognomies mainly distributed in central-western Cerrado region (Ratter et al 2003). It can withstand drought periods, as well as poor and well-drained soil (Burkart 1952;Lorenzi 2000;Rodrigues & Tozzi 2012). Leptolobium elegans and Casearia sylvestris are two of the 11 keyspecies in shrub-grassland and rupicolous Cerrado in Paraná and São Paulo states in Brazil (Moro 2012).…”

Cerrados in Argentina? Structure, diversity and biogeography of the woody component of a savanna in the Misiones Province

The Teyú Cuaré field, in Misiones province, Argentina, has been renowned for its flora and physiognomy, which led researchers to indicate that it could be a relict of Cerrado biome. We analyzed the floristic structure of the woody component of a savanna community in this site, and discussed the processes that could contribute to the permanence of this vegetation type over time. Perimeter and height of all woody individuals ≥ 10 cm of perimeter at soil height were collected in 12 square plots (400 m2 each one). We found 15 families and 17 species in our site and compared the woody flora surveyed at this site with the flora of other Cerrado áreas from Brazil and Paraguay. Leptolobium elegans had the highest importance value. The woody flora of the área is closely related to the Cerrado areas from Paraná state in Brazil and Canindeyú and Amambay in Paraguay. This site probably reflects old open physiognomies which were predominant in Misiones and Southern of Brazil in the late Pleistocene and middle Holocene. We inferred that the permanence of open physiognomies at Teyú Cuaré is probably related to mechanisms that act at different levels, such as geological, edaphic, anthropic, and fire disturbance.

“…Leptolobium elegans é reconhecida pela corola não papilionácea e pelos folíolos que variam de elípticos a oval-lanceolados. Ocorre na Argentina, Paraguai e no Brasil, onde distribuise em domínio de Cerrado e em florestas baixas semideciduais (Rodrigues & Tozzi 2012), nas regiões Centro-Oeste e Sudeste, limitando ao Sul no estado do Paraná (BFG 2015). No estado de São Paulo a espécie é encontrada exclusivamente em fisionomias de Cerrado (Tab.…”

ResumoNeste estudo foram coletados os indivíduos arbóreos e arbustivos da subfamília Papilionoideae na região noroeste do estado de São Paulo, Sudeste do Brasil. A área possui a vegetação mais fragmentada do Estado e é ainda pouco conhecida quanto à composição da flora. Foram registradas 19 espécies arbóreas de Papilionoideae reunidas em 11 gêneros e três tribos. As tribos mais representativas foram Sophoreae, com Bowdichia, Leptolobium, Myroxylon, Ormosia e Sweetia, e Dalbergieae com Andira, Centrolobium, Machaerium e Platypodium, enquanto Dipterygeae foi representada por Dipteryx e Pterodon. O gênero com maior número de espécies foi Machaerium, com oito, seguido por Leptolobium, com duas. Os demais gêneros foram representados por uma espécie cada. Os dados de distribuição das espécies apontam para uma flora regional composta por espécies com ampla distribuição no domínio Cerrado, do Brasil central, e espécies que ocorrem prioritariamente no domínio de Mata Atlântica, no Brasil oriental. Chaves para identificação, descrições e ilustrações dos táxons encontrados são apresentadas. Palavras-chave: Fabaceae, Faboideae, Cerrado, Floresta Estacional Semidecidual, florística. AbstractIn this study, we collected woody plants of Papilionoideae, Leguminosae, in the northwest region of São Paulo state, southeastern Brazil. The study area has one of the most fragmented vegetation within the context of the region, and it is still poorly known about the flora. Nineteen species were recorded in eleven genera and three tribes. The most representative tribes were Sophoreae, with the genus Bowdichia, Leptolobium, Myroxylon, Sweetia and Ormosia; tribe Dalbergieae, with Andira, Centrolobium, Machaerium and Platypodium, and tribe Dipterygeae represented by Dipteryx and Pterodon. Machaerium presented the highest number of species, with eight, followed by Leptolobium, with two species. The other genera were represented by one species each. The species distribution data showed that the regional flora consists of species with wide distribution in the Cerrado, in central Brazil, and species that occur primarily in the Atlantic forest in eastern Brazil. Keys, descriptions and illustrations of the taxa found are displayed. Keywords: Fabaceae, Faboideae, Cerrado, Semideciduous Forest, floristic. Análises filogenéticas e características morfológicas sustentam o monofiletismo de Papilionoideae (Doyle et al. 1997;Pennington et al. 2001;Wojciechowski et al. 2004;Cardoso et al. 2012), a qual é a maior das subfamílias de Leguminosae, com aproximadamente 13.800 espécies distribuídas em 483 gêneros e 28 tribos, de distribuição cosmopolita (Lewis et al. 2005). As espécies de Papilionoideae são caracterizadas pelas folhas pinadas, uni a multi-folioladas e pelas flores papilionáceas com simetria zigomorfa e prefloração imbricada vexilar, exceto nas espécies das tribos Sophoreae e Swartzieae que possuem flores geralmente actinomorfas (Lewis et al. 2005). No Brasil ocorrem cerca de 100 gêneros e 1100 espécies e, deste total, aproximadamente 67 gêneros ...
