A scrambling or occasionally twining herb or sub-shrub. Leaves are trifoliate, composed of three oval-shaped leaflets. These may taper to a point or remain broad. Leaflet surfaces usually hairless. Flowers are typical ëpeaí flowers of dark blue or purple. Flowers are followed by short, relatively broad, straight or slightly curved pods. Usually less than 6 seeds per pod. These are dark and firm at maturity, but more rounded than G. clandestina.
