Tylecodon pygmaeus is a species of the genus Tylecodon in the family of thick-leaf plants (Crassulaceae).
description
Tylecodon pygmaeus grows as a small and sparsely branched plant and becomes 10 to 20 centimeters high. The smooth and gray shoots arise from an underground, bulbous base that has pinkish-brown tissue and is up to 7 centimeters in diameter. The shoots have a diameter of 8 millimeters at the base and taper to 3 millimeters towards the tip. The obovate, linear-lanceolate to almost petiolate and club-shaped leaves are covered with shiny, translucent, heart-shaped to spherical and crystal-like hairs and are 2 to 50 millimeters long and 5 to 45 millimeters wide. The hair is wedge-shaped at the base and the tip is blunt.
The inflorescence consists of thyrses up to 4.5 centimeters high , bearing one to three monochasia , on each of which there are one to three upright individual flowers. The flower stalk becomes 5 to 15 millimeters long. The pale yellowish green and cylindrical corolla is 6 millimeters long. The extended and later bent back tips are as long as the flower tube.
