Tylecodon peculiaris is a species of the genus Tylecodon in the family of thick-leaf plants (Crassulaceae).
description
Tylecodon peculiaris grows geophytically as a very small plant and reaches a height of 1 centimeter. It forms an elongated to depressed-spherical caudex, from which two to three fleshy roots arise, which are 1.8 to 3.5 centimeters long and 1.5 to 2.5 centimeters in diameter. They have a gray, peeling bark and a purple-pink inner fabric. The single, up to 7 millimeters high, shoot has a gray and peeling bark and reaches a diameter of 3 to 4 millimeters. A single, sitting and pressed on the ground leaf is formed, which is dark purple-green in color and 12 to 16 millimeters long, 10 to 15 millimeters wide and 8 to 10 millimeters thick. The blade is rounded, egg-shaped, shield-shaped and provided with a deep, central furrow, which is seldom so deep that it appears almost hollow. The leaf surface is finely wrinkled, the ribs are dark green and have purple cells in between, on which sessile, spherical, shiny white and translucent glands are formed.
The inflorescence consists of up to 4.5 centimeters high thyrsen , which carry a single monochasium , on which one to three arching-ascending single flowers stand. The furrowed inflorescence stalk is 2 inches long and purple-black. The flower stalks are 18 to 25 millimeters long, the linear and pointed bracts are pressed and soon wilt. They are 1 to 2 millimeters long. The triangular-lanceolate sepals are covered with dense, club-like and reddish brown hair and are 2 millimeters long and 0.75 millimeters wide. The pale yellowish to yellowish green corolla tube is covered with club-like glandular hairs and is 6 millimeters long and 3 millimeters wide. The greenish tips are 3 millimeters long and 2 millimeters wide, the fruits are 6 to 7 millimeters long.
