Lepidium strongylophyllum. F. v. M. in Benth. FI. Austr. i., 84 ; Menilyalya, J. 
Forrest; Gascoyne River, Polak. Also a variety with velvet downy branches, 
petioles, and pedicels. The large flowers, the long style, as well as the shape 
and size of the fruit, bring this near L. leptopetalum. All these species are 
doubtless excellent fodder-herbs for sheep.
