Eight Segregates from the Neotropical Genus Mascagnia (Malpighiaceae)

Taxonomic revision of Amorimia W.R. Anderson (Malpighiaceae)

“…Amorimia W.R. Anderson is a small genus of Neotropical lianas, comprising 15 species distributed throughout Seasonally Dry Tropical Forests (SDTF) and Rainforests in South America, ranging from Northern Colombia to Southern Brazil and Argentina (Anderson 2006, BFG 2015, Almeida et al 2016a, 2016b, 2017a, 2017b. The genus is monophyletic and currently placed in a basal grade in the Malpighioid clade (sensu Almeida et al 2017b), alongside Ectopopterys W.R. Anderson, Mascagnia (Bertero ex DC.)…”

“…(Davis & Anderson 2010, Almeida et al 2017b. Amorimia is currently recognized by synapomorphies such as the presence of extra-fl oral nectaries on the abaxial side of bracts and bracteoles, petals pubescent on both sides, samaras with two free lateral wings larger than the dorsal wing, and the production of monofl uoroacetate (Anderson 2006, Almeida et al 2017b.…”

“…This study includes full morphological descriptions for all taxa, along with an identifi cation key for its subgenera and species, illustrations, distribution maps, conservation risk Taxonomic history Many species currently treated under Amorimia were previously treated by many authors as part of a much wider and polyphyletic Hiraea Jacq., or of an also polyphyletic Mascagnia. Based on recent systematic and taxonomic studies, we now know that these two artificial assemblages actually represent eight independent lineages (Anderson 2006, Davis & Anderson 2010. Jussieu (1833) described under Hiraea the first two species of Amorimia.…”

“…Johnson (1986) transferred M. psilophylla to Callaeum Small, while Anderson (1987) transferred M. fluminensis to Heteropterys Kunth, and Anderson and Davis (2007) transferred M. lehmanniana also to Heteropterys. Recently, aiming to finally render Mascagnia monophyletic, Anderson (2006) described Amorimia as a new genus, transferring all species from M. sect. Pleuropterys, based on morphological and molecular data (Cameron et al 2001, Davis et al 2001, Anderson 2006.…”

Fibrose cardíaca associada à intoxicação por Amorimia septentrionalis em bovinos

“…Essas rubiaceas ocorrem apenas em regiões de mata atlântica no litoral e zona da mata nordestina ou ocorrem de forma mais restrita em áreas de brejo de altitude no agreste dos Estados de Pernambuco e Paraíba. As espécies de Amorimia, anteriormente classificadas como Mascagnia (Anderson 2006), são encontradas em todas as regiões do Brasil (Mamede 2010) e no nordeste do país causam surtos de intoxicação em praticamente toda região semiárida . No semiárido nordestino são importantes as intoxicações por A. rigida e A. septentrionalis.…”
