Utilization and economic value.

Forage plant of great interest as suspected ancestor of cultivated trigonella (T. foenum-graecum L.). Attractive for grazing but characterized by low forage productivity. Possesses high drought-resistance, grows on poor soils. Useful for utilization in breeding programs in crosses with cultivated Trigonella species.
