de Candolle designated Bourgeaui 3230 at G-DC as the holotype of P. bourgeaui. There is a duplicate in the general herbarium G (coming from the Boissier herbarium), 3 duplicates in P, 1 in K and 1 in L. The collection was made along the Rio Blanco. There is another collection, Bourgeaui 3230 bis, made at Escamella, but, unfortunately, the ‘bis’ has been omitted on the duplicates in several herbaria (BR, C, GH, P, S, US). This explains why some of these duplicates have been erroneously annotated as isotypes of P. bourgeaui although they are showing a quite different, geophytic species.
