Kirk (T.N.Z.I. 14, 1882, 380) described his L. solandri from specimens collected by himself and Enys on "limestone rocks, Broken River Basin, Canterbury". He distinguished it from L. sisymbrioides Hook. f. "by the naked stems, apetalous fls, straight pedicels and narrowly-winged pods". Later (Stud. Fl. 1899, 37) he treated the name as an absolute synonym of L. sisymbrioides. Thellung (Die Gatt. Lepidium 1906, 313) described his var. ovatum from plants collected by Petrie, "East Coast of Otago, Kurow". Silicles broadly ovate-rhombic, subobtuse at base, acute at apex, slightly notched; wings short, obtuse; style distinctly exserted. There is a Petrie specimen in W labelled "Low hills at Kurow, Waitaki R. L. sisymbrioides var.".
