Brassicaceae Burnett in the municipality of Santa Maria, Rio Grande do Sul, Brazil

Abstract

Brassicaceae (Cruciferae) includes invasive species as well as widely cultivated horticultural species. In Santa Maria, Cruciferae species usually occur in environments that have undergone urbanization such as sidewalks, roadsides, walls, near energy poles, etc. The last listing of species of this family in the area was performed by Romeu Beltrão in 1962 and supplemented in 1965. The objective of the current study was to update the number of records of Brassicaceae species that occur in the municipality of Santa Maria, RS, as well as to provide keys for the identification for native and naturalized genera and species. Bibliographic surveys, field collections, herbarium material analysis and data from databases of speciesLink and Flora of Brazil 2020 were carried out, as well as complementary collections from August 2018 to April 2019. The species found were photographed and identified based on the existing literature. Identification keys for genera and species, as well as illustrations, were prepared. All genera had only one representative species in Santa Maria with the exception of Lepidium, which presented three species. There was an addition of three species and one genus in relation to the last survey carried out.
