Notes —Among the two gatherings mentioned in the protologue of A. riedelii by Müller-Argoviensis (1860a), Woodson (1951) selected Riedel 2771 as the type. However, since this gathering has more than one specimen, it was necessary to narrow Woodson’s (1951) typification by electing the material with follicles as the second-step lectotype of A. riedelii (W No. W0038999) (ICN article 9.17; Turland et al. 2018).
Lastly, according to the ICN article 24.3 ( Turland et al. 2018), designations of infraspecific taxa that were intended to include the type of the species to which they were assigned were not validly published whenever they had infraspecific epithets like “ genuinum ” (e.g., “ A. riedelii var. genuinum ” and “ A. riedelii var. genuinum f. microphyllum ”).
Woodson (1951) considered A. riedelii as a synonym of A. pyricollum Müll.Arg. , but Handro (1962) reestablished the former. We agree with the reestablishment of A. pyricollum because A. riedelii presents spatulate leaves (vs. elliptic or obovate) with brochidodromous venation (vs. eucamptodromous), flowers with longer calyx lobes (2–3 vs. 0.9–1.1 mm long), and smaller follicles (1.8–2.2 × 1.1–1.3 vs. 3.6–4 × 2.6–3 cm). Furthermore, after analyzing specimens of A. reductum and A. riedelii , we observed that both have leaves with brochidodromous venation, sessile fasciculate inflorescences, flowers with unequal calyx lobes, and corolla lobes shorter than the tube (2×). So, we consider A. reductum as a synonym of A. riedelii .
