description
Tylecodon striatus grows with a diameter of 2.5 centimeters from an underground, thickened base with up to 6 centimeters in diameter as a little branched small shrub and becomes up to 18 centimeters, sometimes up to 25 centimeters high. The upright to spreading and often climbing shoots reach 5 to 10 millimeters in diameter. Young shoots have a pale gray-green bark with dark stripes, older shoots have yellowish, peeling bark. The rounded and tapering phyllopodia are 1 to 3 millimeters high. The linear to linearly inverted lanceolate leaves are sometimes almost stalk-round and 3.5 to 10 centimeters long and 3 to 6 millimeters wide. The furrowed or rutted upper side of the leaf is rarely flat. At the pointed to blunt tip there is a little pointed tip. Older leaves wither and remain on the shoots.
The glandular to downy-haired inflorescence consists of elongated and up to 35 centimeters high thyrses with 1 to 5 monochasia . The single flowers stand upright or spread out. The flower stalk is 1 to 1.8 inches long. The tubular and bulging corolla is 12 to 15 millimeters long and is greenish brown in color.
