A perennial herb; stems prostrate to ascending, 3-10 dm. long, pilose with soft spreading 

 hairs, angled and channeled; leaves 2-12 dm. long; stipules subulate, 5-10 mm. long, persistent; 

 petiole 1-3 cm. long; leaflets 7-17, oblong to linear-oblanceolate, 1-5 cm. long, 4-12 mm. 

 wide, obtuse or rounded, rarely acutish at the apex, mucronate, glabrous or sparingly pubescent 

 above, silky-pubescent beneath; racemes slender, lax, including the peduncles 7-20 cm. 

 long; bracts subulate; calyx hirsute, the tube 2-3.5 mm. long, the lobes 4-5 mm. long, subulate, 

 attenuate; corolla purplish, about 1 cm. long; banner suborbicular, with a short claw; wings 

 obliquely oblanceolate with an acute basal auricle, short-clawed; pod 4-5 cm. long, 4 mm. 

 wide, straight, short-hirsute, 8-10 seeded; seeds rectangular-reniform, 3 mm. long, 2 mm. 

 broad, somewhat truncate at the ends. Tephrosia scopulorum is a rather densely pubescent
