Stapelia asterias also Aasblume called, is a species of plant from the subfamily of the asclepiadoideae (Asclepiadoideae). Many other species of the genus Stapelia (and other representatives of the Stapeliinae) are also referred to as carrion flowers.
features
Stapelia asterias forms stem succulents , green to gray-green, up to 15 cm high, which are approximately cylindrical to rounded four-ribbed. The diameter of the shoots is approx. 1.5 cm. The habit is quite compact. The leaflets are small, usually well below 5 mm and persistent (when they are dried out). In the case of larger and older plants, stupid leaf rudiments also appear or appear more clearly.
The inflorescence consists of one, more rarely of several flowers, which sit one behind the other on a flower stalk . They are often spread out flat on the ground. The flower stalk is up to 6 cm long. The buds are broadly oval and pointed at the outer end. The sepals measure about 10 × 3 mm and are green, apical also becoming purple. The edges are slightly hairy. The corolla measures up to 11 cm in diameter and is usually flat. It is pink-red, brownish or dark red on the inside, light green on the outside. The surface is usually glossy with transverse wrinkles that stand out in color (often whitish or yellowish). The crown tube is short and rounded pentagonal; the edge of the tube furrowed radially. The crown lobes are relatively long and slender, rounded-triangular to pointed-elongated oval; they measure up to approx. 4.5 × 2.8 cm. They are smooth or slightly hairy on the inside. Occasionally, small papillae also appear. The edges of the corolla apples are often bent outwards and covered with hair. The hair is white or dark brown to dark red. The very variable secondary crown is black-brown. The interstaminal coronary lobes are about 5 mm long and apically tridentate. The staminal corolla lobes are 6 to 7 mm long and stand upright. They have a broad apical process and dorsal wings. The pollinium is yellowish to brownish; the outer shape resembles a D.
The fruits stand individually and are pale brown.
The number of chromosomes is 2n = 22.
distribution
The species occurs in the Western Cape Province of South Africa . It is now also available in cultivation and in specialist nurseries.
