Struthanthus, Loranthaceae, morfometría, análisis multivariado, flora de VenezuelaResumen
Struthanthus Mart. es uno de los géneros más representativos de la Familia Loranthaceae en el Neotrópico. Aun cuando 12 especies son actualmente reconocidas en Venezuela, muchos especímenes de herbario no han sido identificados debido a la ambigüedad que presentan muchos de los caracteres establecidos para identificar las distintas especies. Análisis multivariados llevados a cabo a 144 especímenes de herbario y usando 17 caracteres arrojaron los siguientes 5 grupos: S. corymbifer Rizzini, S. gracilis (Gleason) Steyerm. & Maguire, S. phillyreoides (Kunth) Blume, S. syringifolius Mart. y S. terniflorus (Klotzsch) Eichler, además de la ya descrita S. martianus Dettke & Waechter. Se presenta una clave y las descripciones correspondientes de cada especie reconocida en este análisis del género Struthanthus en Venezuela.
