Carex bracteosa (Kunze ex Rchb.) Kunth [Familia Cyperaceae]

Iconography: Figures 2C, 3C. Additional figures in Boott (1858–1867: tab. 401, 403), Gay (1854: tab. 73, fig. 8), and Wheeler & Muñoz-Schick (2007: 19). Etymology: From the Latin bracteosus, bracteate, presumably in reference to the leaf-like lowermost bract, that usually surpasses the inflorescence. Notes: Carex bracteosa has been recovered in our analyses nested within C.bonariensis in our phylogenetic study, which points to a close relationship between the two taxa. Given their morphological distinctiveness, we retain both taxa at the species rank, although further studies would be desirable to ascertain the true relationships between C. bracteosa and C. bonariensis. Wheeler & Muñoz-Schick (2007) designated a lectotype for C. bracteosa. However, they did not note that C. bracteosa was to be treated as a combination of the earlier Vignea bracteosa Kunze ex Rchb. through the attribution of both names in their respective protologues to Kunze (ICB Art. 41.3, Ex. 3, Turland et al., 2018). Accordingly, V. bracteosa was still in need of typification. We proceed to designate the lectotype for that name using the same voucher that Wheeler & Muñoz-Schick (2007) designated as the type of C. bracteosa. Cited from southern Chile (CLS) by Govaerts et al. (2020+), the citation seems to be erroneous (see Rodríguez et al., 2018).
