Describes leaf movement in Erythrina herbacea. At night, leaflets are oriented with tips pointing downwards. Leaflets rise in the morning and by noon reach a maximum elevation of about 60 degrees above the horizontal plane. Leaflets then rotate around the midrib by an average of 40-50 degrees. This adaptation allows the plant maximize light interception in the morning and early afternoon.
