Faucaria is a plant kind from the family of aizoaceae (Aizoaceae). The botanical name of the genus is derived from the Latin noun “faux” for “throat” and refers to the serrated leaves of the genus, which look like an open, toothed animal throat.

description

The plants of the genus Faucaria grow compact. Some species develop short, thick rhizomes with age , others have somewhat thick tap roots . Their dark green, yellow-green, reddish purple or rarely bluish leaves are broadly triangular. The leaf margins are white and gnarled, clearly serrated or rarely smooth. In some species, the teeth are elongated and end in a thin thread. The epidermis is smooth and rarely raised.

The individual bractless flowers sit between the leaves. There are five sepals . Their petals are yellow to golden yellow. There are no thread-like staminodes . The yellow stamens are often white at the base. The stigmas stand as high as the stamens are long. There are five nectaries .

The five- (rarely six-) fanned capsule fruits sit on stems up to 3.5 millimeters long. They are compressed laterally, broadly bell-shaped at the base and either almost hemispherical or almost conical at the top. The flaps of the fruit have very wide flap wings that only open once. The dark brown, pear-shaped to tetrahedral seeds are 1.4 to 1.7 millimeters long and 0.9 to 1.4 millimeters wide.

Systematics and distribution

The distribution area of ​​the genus Faucaria extends in South Africa from the western districts of the Western Cape Province through parts of the Eastern Cape Province . The plants often grow under bushes on stony ground and only rarely in clay. The amount of precipitation in March and November is more than 200 millimeters.

It was first described in 1926 by Gustav Schwantes . The holotype is Faucaria tigrina . According to Heidrun Hartmann (* 1942) the genus Faucaria includes the following species:
