LUEBERT, Federico. Los géneros de Heliotropiaceae en Argentina. Bol. Soc. Argent. Bot. [online]. 2017, vol.52, n.4, pp.787-796. ISSN 1851-2372.

The generic delimitation within Heliotropiaceae has changed in the past years. However, these changes are not reflected in recent taxonomic publications on the group in Argentina. In this contribution, the taxonomy of the genera of Heliotropiaceae in Argentina is updated and all accepted species are enumerated. Brief generic descriptions and a key to distinguish the genera are provided. The genera of Heliotropiceae accepted in this work are Euploca, Heliotropium, Ixorhea and Myriopus, all of them present in Argentina. Lectotypes for Heliotropium hasslerianum (≡Euploca hassleriana) and Heliotropium patagonicum are here selected and the new combination Heliotropium lilloi (based on Tournefortia lilloi) is proposed in order to complete the taxonomic treatment of the family in Argentina.

Palabras clave : Boraginaceae; Boraginales; Heliotropium; Taxonomy; Tournefortia.
