Resumo: The genus Heterothalamus Lessing and genera allied are studied, as a contribution to the knowledge of south-american flora, especially from Brazil, Argentina and Uruguay. The genus Heterothalamulopsis is a taxonomic novelty. Monotypic until this moment, it is here described, illustrated and commented about its morphological characteristics. Heterothalamulopsis wagenitzii is a dioecious species of small glandulous and ramified shrubs, provided with persistente bristled and broad apex pappus in male flowers, and with ligulate female flowers, protected by persistent paleas. The species, endemic of southern Brazil, occurs only on the border of the “Aparados da Serra Geral”, in the states of Rio Grande do Sul and Santa Catarina. The genus Heterothalamus comprises three polygamo-dioecious or imperfect-dioecious species of small glandulous and ramified shrubs, characterized by the presence of 1-2-series of radial, female or neutral flowers, in functional male heads, and by the presence of ligulate flowers, protected with persistent paleas, in female heads. The geographic distribution of the genus includes central Argentina (Provinces of Cordoba, San Luis, La Rioja and Santiago del Estero), Uruguay and southern Brazil (States of Rio Grande do Sul and Santa Catarina). The three species of Heterothalamus are described and illustrated, beeing their geographic distributions represented in maps. Common names, the botanical synonymity and phenological data are also furnished. It is supplied a key to set apart the genera of subtribe Baccharinae Lessing, found in the brazilian, argentinian and uruguayan floras. Another key is furnisched to distinguish the three studied species of Heterothalamus. In the proposal of the new genus Heterothalamulopsis, it was redescribed the subtribe Baccharinae Lessing. The genera Baccharis L. and Baccharidastrum Cabrera were also redescribed, with the aim to elucidate morphological differences with respect to other studied genera. Baccharis czermackii Hochreutiner was presently reduced to the synonymity of Heterothalamus psiadioides Less.

O gênero Heterothalamulopsis constitui uma novidade taxonômica. O gênero, monotípico até o momento, é aqui descrito, ilustrado e tem suas características morfológicas comentadas. Heterothalamulopsis wagenitzii é uma espécie de subarbustos glandulosos e ramificados, providos de pápus com cerdas persistentes e ápice dilatado nas flores masculinas, e de flores femininas carnosas, de ápice ligulado, protegidas por páleas persistentes. A espécie, endêmica do sul do Brasil, tem ocorrência restrita à borda dos “Aparados da Serra Geral”, nos Estados de Santa Catarina e Rio Grande do Sul. O gênero Heterothalamus compreende três espécies polígamo-dióicas ou imperfeitamente dióicas de subarbustos e arbustos ramificados, glandulosos, que se caracterizam pela presença de 1-2-séries de flores radiais, femininas ou neutras, nos capítulos funcionalmente masculinos, e pela presença de flores carnosas de ápice ligulado nos capítulos femininos, protegidas por páleas persistentes. A distribuição geográfica do gênero inclui o centro da Argentina (províncias de Córdoba, San Luis, La Rioja e Santiago del Estero), o Uruguai e o sul do Brasil (estados do Rio Grande do Sul e Santa Catarina). As três espécies de Heterothalamus são descritas, ilustradas e têm suas distribuições geográficas representadas em mapas. Para cada espécie são ainda fornecidos os nomes populares, a sinonímia botânica e dados fenológicos. Foi elaborada uma chave dicotômica para a separação dos gêneros da subtribo Baccharinae Less., incluídos nas floras da Argentina, Uruguai e Brasil. Outra chave é apresentada para a separação das três espécies de Heterothalamus. Na proposição do novo gênero Heterothalamulopsis, foi redescrita a subtribo Baccharinae Lessing. Os gêneros Baccharis L. e Baccharidastrum Cabrera foram também redescritos, visando elucidar diferenças morfológicas com relação aos outros gêneros estudados. Baccharis czermakii Hochreutiner foi presentemente reduzido à sinonímia de Heterothalamus psiadioides Less..Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPESporUniversidade Federal de Santa MariaCentro de Ciências RuraisPrograma de Pós-Graduação em Engenharia FlorestalUFSMBrasilRecursos Florestais e Engenharia FlorestalAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/openAccessBotânicaFitogeografiaTaxonomia vegetalEngenharia florestalCNPQ::CIENCIAS AGRARIAS::RECURSOS FLORESTAIS E ENGENHARIA FLORESTALO gênero Heterothalamus lessing e táxones afinsThe genus Heterothalamus lessing and genera alliedinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisMarchiori, José Newton Cardosohttp://lattes.cnpq.br/2625842621787406Irgang, Bruno EdgarGirardi-Deiro, Ana Mariahttp://lattes.cnpq.br/1985993869287103Deble, Leonardo Paz500200000003600600600600600edc5dbec-40f6-4e04-ab4f-e05b46bdfae3fe1fd3a4-b8a9-4079-b0e8-90883effecac68f50862-5a39-49ad-9b2f-d9d000e1d37e05a92742-383d-42e6-ae62-f2a77b22e259reponame:Repositório Institucional Manancial UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMCC-LICENSElicense_rdflicense_rdfapplication/rdf+xml; charset=utf-8805http://repositorio.ufsm.br/bitstream/1/27307/2/license_rdf4460e5956bc1d1639be9ae6146a50347MD52LICENSElicense.txtlicense.txttext/plain; charset=utf-81956http://repositorio.ufsm.br/bitstream/1/27307/3/license.txt2f0571ecee68693bd5cd3f17c1e075dfMD53ORIGINALDIS_PPGEF_2004_DEBLE_LEONARDO.pdfDIS_PPGEF_2004_DEBLE_LEONARDO.pdfDissertação de mestradoapplication/pdf3055731http://repositorio.ufsm.br/bitstream/1/27307/1/DIS_PPGEF_2004_DEBLE_LEONARDO.pdf99ffc0806e55fdb90338b9f402843c63MD511/273072022-12-12 17:08:35.375oai:repositorio.ufsm.br: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ório Institucionalhttp://repositorio.ufsm.br/PUBhttp://repositorio.ufsm.br/oai/requestouvidoria@ufsm.bropendoar:39132022-12-12T20:08:35Repositório Institucional Manancial UFSM - Universidade Federal de Santa Maria (UFSM)false
