Leaves
All leaves are divided into two rows of 8 to 15 leaflet pairs that are arranged oppositely from one another (pinnately compound). Each leaflet is linear to oblong in outline, approximately to 1 inch long by 2 to 4 mm wide. All leaflets occur on a petiole and a distinctive gland occurs on the underside of the petiole below the first leaflet pair.
Identifying Characteristics
Showy yellow flowers and leaves that are divided into 8 to 15 pairs of oppositely arranged leaflets. Also, the gland that occurs on the petiole below the first leaflet pair helps to distinguish this weed from other weeds with pinnately compound leaves.
