Notes.

Stafleu and Cowan (1976) mentioned that Gibert´s collections are distributed in several European, Argentine and Uruguayan herbaria, but we only found a single specimen of M. Gibert 39, housed at K. Since the Kew Herbarium includes that of Bentham, we indicate this specimen as the holotype of Pithecellobium paraguense . Many South American herbaria, which are still not digitized, may house Gibert’s collections, including isotypes of P. paraguense .
