Much cultivated in Abyssinia and also in India for the extraction of oil. 



De CandoUe gives the Indian synonymy in Prodr. v. pp. 661-2, and divides the 

 species into the two following varieties. 



a. sativa. Leaves elongate-lanceolate, coarsely serrate, branchlets elongated, sub- 

 corymbose. 



/3. angustior. Leaves linear-lanceolate, somewhat dentate, flowering axillary 

 branches very short. 



On the roots of this species grows parasitically Orobanche abyasinica, A. Rich. Fl.
