Gomphrena argentina Seubert (1875: 208)

The protologue of Gomphrena argentina consists of a detailed description that is followed by the indication “Crescit ad vias et fluviorum ripas pr. Cordoba in republica Argentina , Brasiliae contermina: Lorentz n. 386 (in Herb. Eichler)”. The herbarium Eichler is currently housed at B. R. Vogt (pers. com.) informed that this specimen is not acutally at B, as it has been destroyed during the II World War ( Hiepko 1987). I have not been able to trace further exsiccata which can be considered as part of the original material. As a consequence a neotypification is required (Art. 9.7). I here designate as neotype of the name Gomphrena argentina a specimen (a picture) preserved at F (code 0BN003240) which bears a plant corresponding with Seubert’s diagnosis and with the current concept in Gomphrena ( Pedersen, 1987; Townsend, 1993). The choice of a picture at F is related to the fact that this Herbarium houses a large collection of photographic negatives that correspond for sure to authentic material from B (see Grimé & Plowman, 1986).

Type (neotype here designated):— ARGENTINA. “Cordoba”. s.d., Lorentz 386 (F-0 BN 003240!). Image of the neotype available at http:// plants.jstor.org/stable/history/10.5555/al.ap.specimen.f0bn003240.
