Notes —The diagnosis of A. tomentosum presented in “ Flora ” by Martius & Zuccarini (1824) was based on a single collection made by Martius himself, though the indication of the original material (Martius s.n.) was only made later by Martius (1824) in “ Nova Genera et Species Plantarum ”. Since there is one sheet in the herbarium M from the single collection made by Martius (1824) for A. tomentosum that resembles the illustration first mentioned in “ Flora ”, but only published in “ Nova Genera et Species Plantarum ” (plate 34 (M barcode M-0183474)), we elected this sheet as the lectotype (ICN article 9.3; Turland et al. 2018). Furthermore, Müller-Argoviensis (1860a) indicated the gathering Riedel 671 in the prologue of A. tomentosum var. angustifolium but did not cite in which herbarium the type would be deposited. Thus, we chose a material with mature leaves and flowers as the lectotype of A. tomentosum var. angustifolium (W No. W0057117) (ICN article 9.3; Turland et al. 2018). Finally, Müller-Argoviensis (1869) did not cite in which herbarium the type of A. pallidiflorum would be deposited. Therefore, we chose the best-preserved specimen from this collection as the lectotype of A. pallidiflorum (C barcode C10005749) (ICN article 9.3; Turland et al. 2018).
Woodson (1951) and Elsam et al. (2021) considered A. chodatii Hassl. ex Markgr. (not mentioned by Elsam et al. (2021)), A. gomezianum A.DC., A. hilarianum Müll.Arg., A. obscurum Müll.Arg., and A. tomentosum var. claussenii A.DC. (not mentioned by Woodson (1951)) as synonyms of A. tomentosum. We disagree with both authors as we recognize A. gomezianum as a different species and include A. obscurum in its synonym (see the species notes). Also, we treated A. chodatii and A. hilarianum as synonyms of A. subincanum (Castello et al. 2018) and A. camporum, respectively (see the species notes). Lasty, Duarte (1968) described A. gilbertii Duarte, a species that shared some characteristics with A. tomentosum. However, we are still studying its description and types and for now do not have enough evidence to make decisions about its identity. So, we treated A. gilbertii as “ incertae sedis ”. We did the same for A. tomentosum var. claussenii, due to the lack of outstanding diagnostic characteristics in its protologue and our unsuccessful search for types associated with this name.
