A revision and tribal placement of the Argentinean genus Parodiodoxa (Brassicaceae).

Parodiodoxa is a monotypic genus of Brassicaceae endemic to northwestern Argentina. It is poorly known and until now remained the only South American genus of the family that had not been assigned to a particular tribe. Sequence data from the nuclear ribosomal ITS region and the chloroplast trnL int...

Resumo:Parodiodoxa is a monotypic genus of Brassicaceae endemic to northwestern Argentina. It is poorly known and until now remained the only South American genus of the family that had not been assigned to a particular tribe. Sequence data from the nuclear ribosomal ITS region and the chloroplast trnL intron/trnL-F spacer region were used in this study to determine the systematic position of Parodiodoxa. For this purpose, taxa were sampled both at the tribal and generic levels. Results from tribal-level sampling support the inclusion of Parodiodoxa in the tribe Thelypodieae, whereas those at the generic level reveal a relationship to Weberbauera (W. rosulans and W. herzogii). Topologies within the Thelypodieae were poorly resolved, in agreement with previous studies. Morphological characteristics of Parodiodoxa are also discussed in relation to other genera of the tribe.
