The alternate leaves are 10 to 20 cm long, odd-pinnately compound with seven to 15 lanceolate leaflets that are nearly sessile, pointed, and serrate on the margins. It blooms white flowers in late spring to early summer. Inflorescence a large, pubescent, flat-topped panicle, with at least 70 flowers, with the 5 lobes triangular; petals 5, oval, 5-6 mm.
