Our only representative of a boreal and arctic genus, collected in Keweenaw Co. at Copper Harbor in 1895 (O. A. Farwell 850, BLH) and on rocks at Isle Royale in 1933 (P. E. Hebert, ND).

The fruit is pubescent vs. glabrous in those species of Arabidopsis with which this might be confused, as well as somewhat constricted between the seeds. Sometimes called Neotorularia humilis (C. A. Mey.) Hedge & J. Léonard.
