Plants are medium-large to large and upright.
Stems are purplish but are more green in the upper portion of the plant.
Leaf petioles extend downward. Nodes are not swollen. Leaves have a distinct terminal leaflet with four pairs of primary leaflets which are largest near the terminal leaflet. Secondary leaflets vary from two on lower leaves to 6-8 on upper leaves, usually in pairs. The number of tertiary leaves also increases from lower to upper leaves.
