Summary: | Three taxonomic changes are proposed based on intensive collecting of Viscaceae within the Distrito Federal, Brazil. Phoradendron andersonii Rizzini, previously a synonym of P. perrottetii (DC.) Eichler is reinstated based on the following combination of characters: young internodes compressed with sharp angles at the distal ends, short spikes to 2.5 cm long, articles with intermixed male and female flowers, biseriate flowers, and dirty yellow fruits. Phoradendron irwinianum Kuijt is synonymized under P. apiciflorum Rizzini, previously known only from the type from western Minas Gerais. Finding of the type collection of P. brachyklados Rizzini, incorrectly quoted in the protologue, led to the synonymization proposal of this species under P. hexastichum (DC.) Grisebach.
Três mudanças taxonômicas são propostas baseadas em coletas intensivas de Viscaceae no Distrito Federal, Brasil. Phoradendron andersonii Rizzini, previamente considerada sinônimo de P. perrottetii (DC.) Eichler é restabelecida baseada na seguinte combinação de caracteres: entrenós jovens compressos com ângulos agudos na porção distal, espigas curtas com até 2,5 cm de comprimento, artículos mistos de flores masculinas e femininas, flores bisseriadas e frutos amarelo-pardacentos. Phoradendron irwinianum Kuijt é sinonimizada sob P. apiciflorum Rizzini, espécie previamente conhecida apenas do tipo do oeste de Minas Gerais. Por fim a localização do material tipo de P. brachyklados Rizzini, incorretamente citado no protólogo, resulta em proposta para que esta espécie seja tratada como um sinônimo de P. hexastichum (DC.) Grisebach. |
