Baccharis bakeri Heering (1904: 39) View in CoL . —Type: "Reineck & Czermak n. 106. Rio Grande do Sul. Belém Velho an bebuschten Hängen". BRAZIL. Rio Grande do Sul: Porto Alegre, Belém Velho, 12 September 1894, ♂ & ♀, E. M. Reineck & J. Czermak n. 106 (holotype HBG 2 View Materials sheets; isotypes P (00509635) photo!, S (10- 22206) photo!).

Barroso (1976) did not lectotypify Baccharis patens View in CoL . We have designated Sellow d 463 in K (000221906) as the lectotype on the basis of its agreement with the protologue, because it bears more branches and capitula than the remaining isolectotypes, and because of more complete label data, showing clearly the collector and collecting number, when compared to the remaining syntypes. The locality on the label is “ Brasilia ”, however the collection was made in what is now Uruguay, which was annexed by the former Brazilian Empire as the Cisplatina Province during the time when Friedrich Sellow travelled in the region (1822-1823). Barroso (1976) assigned the specimen Gibert 881 in K as type material of B. squarrosa View in CoL , however, without either using the words “type” or “ holotype ”, and did not cite the remaining syntypes. We interpret this as a first-step inferential lectotypification and the uppermost branch of the same collection (K000222090) mentioned by Barroso (1976) is designated here as the second-step lectotype. The remaining branches under the same label and barcoding number are interpreted here as isolectotypes. Choosing just one of the branches is justified because the detached branches of Gibert 881 are mounted on the same sheet with the syntype specimens of King 28, which are stored under two barcoding numbers (K000222088; K000222091), and three branches of the collection Tweedie 1023 (K000222089), which are not types of B. squarrosa View in CoL .
