Chilocardamum

Chilocardamum is a small genus of four herbaceous cress-like species of plants in the family Brassicaceae, only found growing in Patagonia, southern Argentina.

==Taxonomy== It was first described in 1924 by the German botanist Otto Eugen Schulz. The first known species, Ch. patagonicum, was initially classified as a Sisymbrium by Carlo Luigi Spegazzini in 1897. The other three species were more recently moved to this genus from Sisymbrium by the Iraqi botanist Ihsan Ali Al-Shehbaz, when he resurrected the genus in 2006. Dimitria was a monotypic genus created by the Chilean botanist Pierfelice Ravenna to house Ch. onuridifolium in 1972; now considered a synonym of the genus Chilocardamum, it was already synonymised with Sisymbrium by the Argentine botanist M. C. Romanczuk in 1981.
