We saw many examples of this leaves-of-three plant. Although it bears some similarity to Poison Oak, it is in fact a close relative, fellow Sumac (Anacardiaceae) 'Basket Bush' (Rhus aromatica).
Besides being generally woodier and with generally thicker leaves, what most reliably differentiates it is that the front leaf of the leaves-of-three triad is directly attached to the node of the two other leaves; poison oak is attached via a short but distinct petiole.
