Aristida pungens
（重定向自Drinn）
Aristida pungens is a member of the family Poaceae.
The grass is known in Arabic as Drinn. It is a tall perennial plant with deep roots and long leaves. Extremely drought resistant, drinn grows in areas with as little as 70 mm of rainfall per year. A traditional food plant in Africa, this little-known grain has potential to improve nutrition, boost food security, foster rural development and support sustainable landcare.
