ABSTRACT: López, H. A. 1998. Boerhavia cordobensis vs. B. pterocarpa (Nyctaginaceae): which one lives in Argentina?. Darwiniana 36: 159-161.

A comparative study between Boerhavia cordobensis Kuntze and North American specimens of Boerhavia pterocarpa S. Watson allowed to recognize two different taxa: Boerhavia cordobensis, which lives in Central-western Argentina and has been introduced in South Africa, and Boerhavia pterocarpa, confined to the state of Arizona (U. S. A.); thus, the latter is excluded from the Argentinian flora. A key and illustrations are given to differenciate both entities.

Key words: Nyctaginaceae, Boerhavia cordobensis, Boerhavia pterocarpa, Taxonomy.

Palabras clave: Nyctaginaceae, Boerhavia cordobensis, Boerhavia pterocarpa, Taxonomía.
