description
Appearance and leaf
Bivonaea lutea is a slender, bare, annual , herbaceous plant with heights of 4 to 20 centimeters. Several upright to ascending stems can be formed. Stipules are missing.
The short-stalked basal leaves are oblong-spatulate. The leaf margin is entire or toothed.
Flower, fruit and seeds
The flowers stand together in racemose inflorescences . The hermaphrodite flowers are fourfold. The four free, protruding sepals are arranged in two circles. The four yellow petals of the same size are about 3 millimeters long and therefore one and a half times as long as the sepals. The free, a total of six stamens have no appendages and are in two circles with two short stamens on the outside and four long stamens on the inside.
The obverse-shaped, elongated, 5 to 7 millimeter long pods are edged and flattened perpendicular to this with a narrow partition ( angustisept ). The fruit flaps are winged 1 to 2 millimeters wide. Two to six seeds are formed in each fruit compartment . The surface of the seeds is smooth, so there are no wart-shaped glands.
