B. 826 (lectotype P (00755558) photo!, first-step lectotype designated by Barroso 1976: 56, second-step lectotype designated by Müller 2006: 273; isolectotypes G-DC, R!). —Remaining syntypes: BRAZIL. Rio Grande do Sul: s.d., ♀, F. Sellow d616 = M. I. B. 810 (P (00755555) photo!); s. d., ♂, F. Sellow s.n. = M. I. B. 837 (P (00755557) photo!); s. d., ♀, F. Sellow d2067 = M. I.

Eupatorium montevidense Sprengel (1826: 417) . — Type : URUGUAY. "Monte Video. Sello"; s.d., ♀, F. Sellow s.n. (holotype P (00755549) photo!).

Müller (2006) chose Sellow d1893 (P00755558) as lectotype of B. coridifolia . However, Barroso (1976) previously designated the same collection as “ holotype ”, although without indicating the herbarium where this lectotype is housed. Yet, she stated that the duplicate at R is an isotype. The choice by Barroso is here considered as the first-step lectotypification, whereas Müller’s (2006) designation is a second-step lectotypification to accomplish the ICBN requirements (McNeil et al. 2006).
