“…The genus Pueraria has been in existence since 1825 when De Candolle first described and named it after a colleague and friend (De Candolle, 1825). At its outset it consisted of only 2 species, Pueraria tuberosa and P. wallichii.…”

A taxon is defined as polyphyletic when it does not include the last common ancestor of all true members of the taxon, resulting in a number of subgroups not united by a common ancestor. Previous work has suggested Pueraria (Fabaceae) to be polyphyletic. Although several taxonomic treatments have recognized Pueraria as an unnatural grouping since its creation in 1825, and two have put forth taxonomic hypotheses, the polyphyly has never been resolved. The need for further biosystematic research has always been cited as the reason no changes were proposed. This project attempted to address this issue by sampling broadly across phaseoloid legumes with an initial target goal of 156 species including 15 species of Pueraria. Ultimately, 104 species across 69 genera were sampled for AS2 and 116 species across 64 genera for matK.Phylogeny reconstruction was carried out using maximum likelihood and Bayesian inference.Both analyses yielded congruent tree topologies and similar support values. Both previous taxonomic hypotheses show some congruence with the data, but discrepancies do occur. This work provides strong support for the existence of five separate clades within the genus Pueraria, requiring the resurrection of the genus Neustanthus for P. phaseoloides along with the need to create a new genus each for P. stricta, P. peduncularis, and P. wallichii.

“…A espécie foi originalmente descrita como glabra (Candolle 1859), contudo, observou-se em coletas posteriores a presença de esparsos tricomas simples, finos, tricomas de base espessa e glandulares microscópicos, especialmente nos indivíduos jovens; na fase adulta, o indumento é muitas vezes perdido. Assim, acredita-se que o material utilizado para a descrição da espécie tenha perdido o indumento.…”

“…Na descrição original, B. glabra foi caracterizada pelos ramos flexuosos e glabros, folhas com lâminas ovadas, acuminadas e base obtusa a subcordada, margem irregularmente crenado-dentada; estípulas largamente lanceoladas; flores estaminadas com sépalas obovado-oblongas; flores pistiladas com tépalas elípticas, sendo as duas externas menores (Aublet 1775). Begonia smilacina, descrita para a Bahia, foi considerada distinta desta espécie pelas lâminas foliares obovadas e flores estaminadas com "sépalas" ovadas (Candolle 1859(Candolle , 1861. Contudo, verificou-se uma sobreposição das características utilizadas na separação das duas espécies, sendo possível encontrar folhas ovadas, obovadas ou elípticas na mesma exsicata.…”

Resumo -É apresentado o tratamento taxonômico da família Begoniaceae para o estado da Bahia. São reconhecidas 38 espécies, 15 endêmicas e quatro descritas originalmente a partir deste estudo. A maior parte das espécies ocorre na Mata Atlântica (32 espécies), seguida pela Caatinga (11 espécies) e Cerrado (uma espécie). Nove nomes são tratados aqui pela primeira vez como sinônimos. São apresentadas descrições, chave de identificação, dados fenológicos, ilustrações, mapas de distribuição geográfica na Bahia e comentários. Palavras-chave adicionais: Begonia, endemismo, florística, Nordeste, taxonomia.Abstract (Flora of Bahia: Begoniaceae) -The taxonomic treatment of the Begoniaceae from Bahia state is presented. We recognize 38 species, 15 are endemic and four were firstly described based on this study. Most of the species occur in the Atlantic Forest (32 species), followed by the Caatinga (11 species) and Cerrado (one species). Nine names are treated as synonym for the first time here. Descriptions, identification key, phenological data, illustrations, maps of geographical distribution in Bahia and comments are presented.

“…Within this genus, a very interesting group is represented by the species belonging to the G. ephedroides complex, which shows a remarkable morphological variability due to geographical or ecological isolation (Bacchetta et al 2011). From literature data (Candolle 1826;Spach 1844;Valsecchi 1986aValsecchi , 1986bValsecchi , 1993aValsecchi , 1993bDe Marco et al 1987;Brullo et al 1993;Brullo and De Marco 1996;Bacchetta et al 2011), the taxa currently known within this group occur in the Tyrrhenian territory (CW Mediterranean) and are characterized by a narrow or sometimes punctiform distribution. In particular, this group has a main centre of differentiation in Sardinia, where several endemic taxa are present, such as: G. ephedroides DC., G. As concerns the taxonomical position of these species, Spach (1844) includes Genista ephedroides, G. gasparrinii and G. numidica into sect.…”

Analysis of the Genista ephedroides group (Fabaceae) based on karyological, molecular and morphological data

Within the genus Genista, the species belonging to the G. ephedroides complex are examined from karyological, molecular and phenetic point of view. All the examined taxa show a chromosome complement with 2n = 48, occasionally with some accessory chromosomes. In addition, the aneuploid number 2n = 44 was found only in G. ovina, while higher counts (2n = 72 and 2n = 96) are reported for G. tyrrhena ssp. pontiana. As concerns the DNA, the restriction fragment analysis of the ribosomal ITS1 (HaeIII, RsaI) and 5.8S-ITS2 (HaeIII) regions was used; the classification and ordination of the taxa allow to distinguish three clusters: the first including the S-Tyrrhenian taxa, the second all the Sardinian and Balearic taxa, and the third grouping G. numidica and G. cilentina. The phenetic analysis was performed by using 40 morphological characters processed by the NTSYSpc package. The relative cladogram distinguishes three main clades: the most isolated including the Sicilian species, the other two separating the Sardinian and Balearic species from the STyrrhenian and Algerian ones.
