Lepidium rotundnm, DC. Domin, in Fedde, Repert. xi., 

 198 (1913), distinguishes L. eremaeum, n. sp., from L. 

 rotundnm by its elongated racemes, narrow petals, winged 

 seeds, and notch of the pod almost closed by the connivent 

 lobes. It is to be observed, however, that in specimens of 

 L. rotnfidum with an open notch the seeds are also conspicu- 

 ously winged, and the racemes vary greatly in length. The 

 degree to which the lobes of the pod approach or diverge from 

 each other is also variable, especially in var. phlebopetahom, 

 Maid. et. Betche (L. phlebopetalum, F. v. M.). The Tate 

 Herbarium contains a specimen labelled "L. 7'otundum, 79 

 Gully," which agrees with Domin's description of the plant 

 ''collected by R. Tate, Horn Valley, Central Australia, 

 1894." In the same herbarium is a specimen labelled "Z/. 

 rotu?idum — R. Helms, Camp 53." Here the inner margins 

 of the lobes are parallel and close together, resembling the 

 plant from Horn Valley, but the racemes are only 2-3 cm. 

 long. It therefore seems unlikely that L. eremaeum 

 (erroneously printed ''eraemeum" in the Repertorium) is 

 more than a variety, at most, of L. rotundnm.
