description
The geophytic plants grow with upright, more or less branched shoots up to 15 centimeters in height. An underground, spherical tuber with fibrous adventitious roots is formed. The flattened leaves are on a 3 to 15 millimeter long stem, are broadly ovate to circular and are arranged in more than three pairs. They are 3 to 15 millimeters long and 4 to 13 millimeters wide. The entire leaves have a bare surface and are gray-green in color. The leaf base is heart-shaped to spontaneously wedge-shaped, the tip of the leaf is rounded to truncated.
The inflorescence is composed of sessile and loosely arranged, terminal thyrses . The triangular-egg-shaped sepals are up to 2.5 millimeters long and are pointed to blunt. The star-shaped corolla is shaped like a flat cup and reaches 8 millimeters in diameter. It is yellowish green in color and the lanceolate tips of the petals are 3.5 millimeters long. The tips of older flowers are bent back. The stamens are colored yellow.
