ARTICLE Floristic and Characterization of Grassland Vegetation at a Granitic Hill in Southern Brazil Robberson Bernal Setubal1* and Ilsi Iob Boldrini2
Revista Brasileira de Biociências Brazilian Journal of Biosciences http://www.ufrgs.br/seerbio/ojs ISSN 1980-4849 (on-line) / 1679-2343 (print) ARTICLE Floristic and characterization of grassland vegetation at a granitic hill in Southern Brazil Robberson Bernal Setubal1* and Ilsi Iob Boldrini2 Received: March 31 2009 Received after revision: November 19 2009 Accepted: November 20 2009 Available online at http://www.ufrgs.br/seerbio/ojs/index.php/rbb/article/view/1209 ABSTRACT: (Floristic and characterization of grasslands vegetation of a granite hill in Southern Brazil). A floristic and vegeta- tion study was carried out in the grassland formations at Morro São Pedro, Porto Alegre municipality, Rio Grande do Sul State, a granitic elevation area, so far poorly surveyed, that cradles important natural vegetation remnants of the region. After the study, which lasted from April 2005 to March 2009, we found 497 angiosperm species, distributed in four main grassland formation types: dry grassland, rocky grassland, humid grassland and wetlands. Among the species list three species are noteworthy: Alstroemeria albescens, a new species for the science, Lepuropethalon spathulatum, a new record for Southern Brazil, and Thrasyopsis juergensii, a new record for the Pampa biome. Based on our results and on support from other papers we concluded that ca. 65% of the grassland species present in the granitic hills of the region belong to seven main botanical families (Astera- ceae, Poaceae, Fabaceae, Cyperaceae, Rubiaceae, Verbenaceae and Apiaceae). The species belonging to these families are also determining in the vegetation phytophysiognomical and structural composition, so that cespitous grasses predominate in the landscape, shaping a continuous gramineous layer. -
New Species of Baccharis (Asteraceae) from Western Mexico
Nesom, G.L. 2018. New species of Baccharis (Asteraceae) from western Mexico. Phytoneuron 2018-28: 1–20. Published 30 May 2018. ISSN 2153 733X NEW SPECIES OF BACCHARIS (ASTERACEAE) FROM WESTERN MEXICO GUY L. NESOM 2925 Hartwood Drive Fort Worth, Texas 76109 [email protected] ABSTRACT Four new species of Baccharis are described from western Mexico and one is raised in rank from variety. Baccharis charucoensis Nesom, sp. nov. , from the Rio Mayo region along Chihuahua-Sonora border, is similar in habit and related to B. macrocephala of eastern Mexico but differs in its linear leaves with stiffly ciliate margins. Baccharis horizontalis Nesom, sp. nov. , from western Durango and adjacent Sinaloa, is similar and closely related to the widespread B. serrifolia but differs in its sessile leaves and distant geographical location. Baccharis supplex Nesom, sp. nov. , from southeastern Durango (mpios. Mezquital and Súchil) differs from the sympatric B. thesioides in its rhizomatous habit with one or few stems from the base, broader leaves, and few-flowered capitulescence. Baccharis praetermissia Nesom, sp. nov. , from the Cape Region of Baja California Sur, is distinct in its erect habit, nearly glabrous stems, glabrous, elliptic leaves, dense capitulescence, and non-accrescent pappus, and disjunct geography within sect. Aristidentes . Baccharis multiflora var. herbacea McVaugh from western Michoacan is recognized here at specific rank: Baccharis herbacea (McVaugh) Nesom, comb. et stat. nov. Each of these five species apparently is rare. In a review of Baccharis in CAS-DS, TEX-LL, and UC-JEPS, collections indicate that four distinct species are without names. They are formally described here, and another is recognized by raising its rank from variety to species. -
Asteraceae: Astereae)
Heiden, G. 2013. Two new combinations in Baccharis (Asteraceae: Astereae). Phytoneuron 2013-78: 1–2. Published 10 October 2013. ISSN 2153 733X TWO NEW COMBINATIONS IN BACCHARIS (ASTERACEAE: ASTEREAE) GUSTAVO HEIDEN Departamento de Botânica, Instituto de Biociências Universidade de São Paulo Rua do Matão, Travessa 14, 321 São Paulo, SP 05508-090, Brazil [email protected] ABSTRACT The newly proposed genus Lanugothamnus Deble is considered a synonym of Baccharis , since phylogenetic data strongly support the monophyly of Baccharis sensu lato and reject the current circumscription of Baccharis subg. Tarchonanthoides , on which the circumscription of the new genus is based. Two new combinations are proposed: Baccharis anabelae (Deble) G. Heiden and Baccharis pluricapitulata (Deble) G. Heiden, based on taxa originally described in Lanugothamnus . KEY WORDS: Baccharidinae, Compositae, new combinations, nomenclature Baccharis L. comprises between 338 and 400 species occurring from the USA to southern Argentina and Chile (Bremer 1994; Müller 2006) and is characterized by the usually tufted indumentum of the leaves and stems and the common occurrence of dioecy (Müller 2006). Heering (1904) published the first subgeneric classification of Baccharis and included the subgenera Baccharis , Molina (Pers.) Heering, Pteronioides Heering, Stephananthus Heering, and Tarchonanthoides Heering. The genus has been subject of recent alterations in its circumscription. Hellwig (1993) proposed segregate Neomolina F.H. Hellw. and Pingraea Cass. from Baccharis and suggested that the species he included in the informal group “Lanugobaccharis” should be considered equivalent to a genus as well. On the other hand, broader circumscriptions of Baccharis were proposed by Nesom (1988) and Müller (2006) with the merging of monoecious ( Baccharidastrum Cabrera), gynodioecious ( Heterothalamus Less.), and polygamous taxa ( Baccharidiopsis G.M. -

It is closely related to Baccharis plummerae subsp. plummerae but differs in having narrow, subentire, typically conduplicate, sparsely villous to mostly glabrous leaves with glands occurring in depressions on the adaxial surface, more cylindrical inflorescences, and a distribution in open chaparral vegetation. The new taxon shares some characteristics with B. plum merae subsp. glabrata of northwestern San Luis Obispo County, e.g., smaller leaves, reduced vestiture, and occurrence in scrub habitat, but the two taxa appear to have developed independently from B. -

Preliminary Phylogeny of Diplostephium (Asteraceae): Speciation Rate and Character Evolution
NUMBER 15 VARGAS AND MADRIN˜ A´ N: SPECIATION AND CHARACTER EVOLUTION OF DIPLOSTEPHIUM 1 PRELIMINARY PHYLOGENY OF DIPLOSTEPHIUM (ASTERACEAE): SPECIATION RATE AND CHARACTER EVOLUTION Oscar M. Vargas1,2 and Santiago Madrin˜a´n2 1Section of Integrative Biology and the Plant Resources Center, The University of Texas, 205 W 24th St., Stop CO930, Austin, Texas 78712 U.S.A., email: [email protected] 2Laboratorio de Bota´nica y Sistema´tica Universidad de los Andes, Apartado Ae´reo 4976, Bogota´, D. C., Colombia Abstract: Diplostephium comprises 111 neotropical species that live in high elevation habitats from Costa Rica to Chile. Primarily Andean, the genus seems to have undergone an adaptive radiation indicated by its high number of species, broad morphological variation, and diversification primarily in an ecosystem (pa´ramo) that formed within the last 2–5 my. Internal transcriber spacer (ITS) sequences and several chloroplast markers, rpoB, rpoC1, and psbA-trnH were sequenced in order to infer a preliminary phylogeny of the genus. The chloroplast regions showed no significant variation within the genus. New ITS data were therefore analyzed together with published sequences for generating a topology. Results suggest that Diplostephium and other South American genera comprise a polytomy within which a previously described North American clade is nested. Monophyly of Diplostephium was neither supported nor rejected, but the formation of a main crown clade using different methods of analysis suggests that at least a good portion of the genus is monophyletic. A Shimodaira-Hasegawa test comparing the topology obtained and a constrained one forcing Diplostephium to be monophyletic showed no significant difference between them.
