Pinnae deeply pinnatifid to within 1 mm of costa, 3--9(--13) × 1--2(--2.5) cm; segments oblong to linear, somewhat oblique, entire to crenulate; proximal pair of veins from adjacent segments meeting margin above sinus. Indument abaxially of moderately to densely set hairs to 1 mm on rachises, costae, and veins, glands lacking or yellowish to light orangish, mostly sessile on blade tissue; blades adaxially often with hairs on veins.
