Small collections, great findings: three new species and two new state records for Asteraceae from Brazil

open access: yesNordic Journal of Botany, Volume 2025, Issue 12, December 2025.
The BHZB herbarium was founded in 1993 with about 16 787 registers – a number that has to be considered as small when compared to larger herbaria in Brazil. In the BHZB, 97.5% of the vouchers are from the Minas Gerais state (ca 16 372 specimens), with Asteraceae being the best represented family.
