Tylecodon similis is a species of the genus Tylecodon in the thick-leaf family(Crassulaceae).

description

Tylecodon similis grows as a very small and sparsely branched, upright to creeping plant and is up to 10 centimeters high. The individual shoot arises from an underground tuber with a diameter of up to 3 centimeters, which is provided with a gray-brown and peeling bark. The shoot is up to 12 centimeters long and rarely forms side shoots. It reaches a diameter of 1.5 to 3 millimeters and is straight. But there are forms from the Karrachab area, which develop zig-zag-shaped bent shoots. The gray bark has black spots or stripes. The very different leaves are very close together at the tip of the shoot. They are flat to almost stem-round, circular, broadly obovate to heart-shaped, glabrous or with warts and green. They are 3 to 15 millimeters long and 3 to 7 millimeters wide. The top is grooved to concave, the mostly chestnut-brown underside is convex.

The inflorescence consists of up to 3 centimeters long monochasia on which the one to three upright single flowers with linear bracts stand. The flower stalk becomes about 1 centimeter long. The tubular to almost urn-shaped corolla is 6 to 8 millimeters long and 2 to 3 millimeters wide. It is pale yellow or cream-colored and the bent-back tips are 1.5 to 2 millimeters long. The inside of the tube is usually densely hairy to almost bald.

Systematics and distribution
