OENANTHE CROCATA (APIACEAE, APIOIDEAE), PLANTA TÓXICA NUEVA PARA LA FLORA ADVENTICIA DE ARGENTINA Y AMÉRICA

Abstract

Con el hallazgo de Oenanthe crocata en la provincia de Buenos Aires, una nueva especie se suma a la flora adventicia de la Argentina y de América. Se trata de una planta tóxica, originaria de Europa; la toxicidad se debe a la presencia, particularmente en las raíces, de enantotoxina, un alcohol poliacetilénico. En los países de origen se han reportado casos de envenenamiento y muerte en ganado y seres humanos debido a la ingestión de tubérculos radicales. La identificación de la especie se corroboró con la comparación de la región ITS de ADN nuclear ribosomal del material argentino con las secuencias nucleotídicas disponibles en GenBank y con un análisis filogenético de máxima verosimilitud de las especies de Oenanthe. Además se remite, por primera vez, Oenanthe divaricata a la sinonimia de O. crocata. En este aporte se describe e ilustra la nueva cita, se provee un mapa de distribución y se señalan los caracteres diferenciales con otras apioideas que crecen en Argentina.

The presence of Oenanthe crocata in Buenos Aires province adds a new species to the adventive flora of Argentina and America. This is a toxic plant native from Europe; its toxicity is due to the presence, particularly in roots, of oenanthotoxin, a polyacetylenic alcohol. In its countries of origin, cases of poisoning and death of cattle and humans have been reported by the ingestion of the radical tubercles. The identification of the species was corroborated by comparing the nrDNA ITS region of the argentine material to all the nucleotide sequences available at GenBank, and by performing a maximum likelihood phylogenetic analysis of Oenanthe species. Moreover, Oenanthe divaricata is referred to the synonymy of O. crocata for the first time. This contribution describes and illustrates this new record, provides a distribution map and points the differential characters with other apioids that grow in Argentina.
