Morphology General Habit
Weak annual herb to 0.9 m tall, sometimes forming a spreading mat to 45 cm in diameter from the taproot.
Morphology Stem
Main stem somewhat woody at the base; young branches glabrous to densely covered with tubercular-based yellowish bristly hairs.
Morphology Leaves
Leaves 14–46-foliolate; leaflets 2–4(7) × 0.8–1.2(2) mm, linear-oblong, rounded and mucronulate at the apex, obliquely rounded at the base, entire or very slightly serrulate near the apex, glabrous or with a few marginal setae; midrib and venation often purplish but the latter usually obscure; petiole and rhachis together 1–3(5) cm long, glabrous or with tubercular-based hairs; petiolules 0.3 mm long; stipules 3–10 × 1–1.5 mm, lanceolate, straight, spurred, persistent.
