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

description

Tylecodon schaeferianus grows as a very small and much branched, spreading plant with several intersecting shoots and thus forms small cushions. The shoots arise from a gray tuber with a flaky bark that can be up to 10 centimeters in diameter. The spreading and ascending shoots sometimes form aerial roots and are 2 to 5 millimeters in diameter. The irregular gray-brown bark looks gnarled due to the isolated phyllopodia. The obovate and elliptical to circular leaves are 5 to 15 millimeters long and 6 to 12 millimeters thick. They are a little compressed dorsiventrally and at the blunt tip they have a reddish, patched point.

The inflorescence consists of up to 2.5 centimeters high thyrsen , which carry one or two monochasia , on which the one or two upright single flowers are. The flower stalk is up to 1 centimeter long. The pink or white, bald and tubular corolla is 7 to 10 millimeters long and 4 millimeters wide. The extended to recurved tips are 4 millimeters long.

Systematics and distribution

Tylecodon schaeferianus is widespread in southern Namibia and in South Africa in the provinces of Northern Cape and Western Cape in the Succulent Karoo . It was first described in 1923 as Cotyledon schaeferiana by Kurt Dinter . Helmut Richard Tölken placed the species in the genus Tylecodon in 1978 .

Synonyms are Cotyledon hoerleiniana Dinter , Cotyledon schaeferi Dinter , Adromischus keilhackii Werderm. , Cotyledon sinus-alexandri Poelln. and Tylecodon aridimontanus G. Will .
