Gomphrena graminea Moquin-Tandon (1849: 416)

Moquin-Tandon (1849: 416) provided a detailed description of Gomphrena graminea , and he also mentioned the following two specimens (syntypes, Art. 9.5): “In Brasiliae prov. S. Pauli (Tweedie! n. 116, Lund! n. 741)”.

Holzhammer (1956: 179) stated “Typus: Brasilia, São Paulo (Tweedie no. 116) Herb. Kew.”. However, actually there are two specimens collected by J. Tweedie and preserved at K. The first one is unnumbered, and the other sheet is numbered as “115”. Unfortunately, none of the labels on these specimens match the protologue. In De Candolle’s herbarium at G, I traced two further sheets (codes 00478884, and 00478884) bearing plants collected by P. Lund, while a duplicate is deposited at P (code 04960171). Among these three specimens, those at P include a label in Moquin’s handwriting (see also Burdet 1977). As a consequence, I prefer to designate the P-04960171 as the lectotype of Gomphrena graminea .

Additional material seen:— BRAZIL. “Found on inter moist fields of río Uapuhy”. J. Tweedie 115 (K-000583063!); ibidem (K-01209046!), BRAZIL. “camp. Taubaté” Lund s.n. (G-00478885!).
