description: 1. Gomphrena filaginoides Martens & Galeotti (1843: 350) ≡ Xeraea filaginoides (Martens & Galeotti) Kuntze (1891:
545).
Lectotype (here designated):— MEXICO, Oaxaca, dans les champs de la Misteca Alta et de la cordillère de Yavezia, 6000-7500 ft., April 1840, Galeotti 441 (BR0000006950835!, image available at https://www.botanicalcollections.be/specimen/ BR0000006950835); isolectotype P00622630!, image available at https://science.mnhn.fr/institution/mnhn/collection/p/item/p00622630).
= Gomphrena decumbens Jacquin (1804: 41–42) var. nana Stuchlík (1912: 158) ≡ Gomphrena nana (Stuchlík) Standley (1917: 150).
Lectotype (here designated):— MEXICO, Manzanillo, 1 to 31 December 1890, Palmer 911 (Z000000292!, image available at https:// www.digitalis.uzh.ch/media/specimen/0/Z-000000292.jpg; isolectotypes: US00102786!, image available at http://n 2t.net/ark:/ 65665/30cd25a65-9c6c-4a31-8bd1-102acb23fdd6; US 00931477!

Typification of the name Gomphrena filaginoides: — Martens & Galeotti (1843: 350) provided, after the description, the provenance (“dans les champs de la Misteca Alta et de la cordillère de Yavezia, de 6,000 à 7,000 piedes”); the citation “ Coll. H. Gal. N ° 441 bis” (which refers to Galeotti’s collection) is also given. We traced two specimens part of Galeotti’s collection (original material), one deposited at P (barcode P00622630) and another at BR (barcode BR0000006950835); both of these specimens match the protologue. BR0000006950835 (Fig. 1) is here designated as lectotype; P00622630 is an isolectotype. Note that Galeotti’s collection and types are mainly preserved at BR (HUHIndex of Botanists 2023).
Typification of the name Gomphrena decumbens var. nana:— The protologue of Gomphrena decumbens var. nana (Stuchlík 1912: 158) consists of a brief morphological description, the citation of a collector and collection number (“Palmer 911”), as well as the mention of three herbaria, i.e. “Berl., Petr., Zür” (respectively, B, LE, and Z). One specimen is located in Z (barcode Z000000292), whereas duplicates were found at US (barcodes US00102786 and US00931477). The specimen Z000000292 (Fig. 2) is here designated as lectotype being well preserved, showing mature reproductive structures, and matching the protologue.
Moquin-Tandon (1849: 417) includes Gomphrena filaginoides in the section “ species non tatis notae ” (= species not sufficiently known). Standley (1917: 153) cites G. filaginoides as a doubtful species and stated that it could be G. nana. Later, Holzhammer (1956: 196) mentioned that, according to the diagnosis and the original material (Palmer 911), the habit of G. decumbens var. nana is not distinct from G. filaginoides; likewise, he reported the inflorescences of “ nana ” as coinciding with those of the type material of G. filaginoides. After reviewing the type material of G. filaginoides (Fig. 1) and G. decumbens var. nana (Fig. 2), we agree with Holzhammer (1956) and consider G. decumbens var. nana as a heterotypic synonym of G. filaginoides.
