Tylecodon cordiformis grows dwarfish and sparsely branched with an elongated and spherical base, the gray-brown bark of which peels off. The plants reach a height of 5 centimeters and a diameter of 2 centimeters. The short and gray shoots are 5 to 45 millimeters long and 4 to 8 millimeters wide. They are provided with triangular phyllopodia and covered with tiny hair. 2 to 4 leaves are formed, which stand in terminal rosettes on almost upright petioles up to 8 millimeters long. The shiny dark green leaf blades are heart-shaped and 5 to 8 millimeters long and 7 to 10 millimeters wide. They are densely covered with white upright hair.

The inflorescence is formed by flat and ascending thyrses and is up to 10 millimeters high. The rectangular sepals are 2 millimeters long and 0.8 millimeters wide and are rounded at the tip. The tubular and lime-green corolla tube is somewhat widened towards the throat and becomes 10 millimeters long and 5 millimeters wide. It is thickly covered with hair. The extended and later slightly bent back tips are 4 millimeters long and 2.5 millimeters wide. The oblong nectar flakes are spread out and 0.5 millimeters long and 0.8 millimeters wide.
