Description
Vegetative characteristics
Stapelia flavopurpurea grows as a perennial succulent plant, forming low lumpy growth forms. The stem succulents Stems are up to about 10 cm long / high, and in cross-section vierrippig with a diameter of about 1 centimeter. Copies to ideal locations can also be significantly larger. The sides of the stem axis are flat or slightly curved concave. The warts are indistinct, the leaves fell. The pale stipule rudiments are dull.
Generative features
The flowers are usually solitary, or the inflorescence is wenigblütig and are randomly distributed. The flowers facing outward. The flower stalk or peduncle is strong and reaches a length of about 3 inches (rarely more).
The flowers of Stapelia flavopurpurea are smaller than those of most other Stapelia species and lack of unpleasant odor, which is otherwise so typical of this genus. The hermaphrodite flowers are radial symmetry, fünfzählig and spread flat with a diameter of 3 to 4 centimeters.
The five petals are fused basally, the central part of a funnel. A wide ring around the central depression of the crown until the approach of the corolla lobes is very hairy. The clavate hairs ( trichomes ) are white to dark purple. The lanceolate Kronblattzipfel measure 1.3 to 1.6 inches in length. The edges are strongly bent outwards. You are outside glabrous or only slightly covered with downy hairs. Inside they have predominantly transverse to the longitudinal axis extending wrinkles. The wrinkles are often finely roughened. The crown is pale yellow exterior, interior green, yellow, brown or red.
The corona is whitish. The interstaminalen Nebenkronblattzipfel are 3 mm long, oblong and scored with a clear tip or something. You see straight, the pages are bent inward. The staminal Nebenkronblattzipfel are 6 mm long, ovate at the base, subulate toward the top or thready. You stand upright, walk together, then turn to the outside. The tips are club-shaped. The crescent-shaped pollinia measuring 0.7 × 0.3 mm.
Occurrence
The not very common, but widespread Stapelia flavopurpurea comes in Namibia, Botswana and in South Africa ( Western Karoo to North Cape Province). It grows between rocks at the base of shrubs.
Synecology
The flowers of Stapelia flavopurpurea smell slightly different depending on the color. While the reddish forms, like most other species of the genus Stapelia slight odor of carrion, have the greenish to yellowish flowers rather a fruity sweet smell. The reddish forms have not only the malodorous still a fruity- sweet-smelling component. Although some large ( Carrion ) flies are attracted by the foul-smelling reddish flowers still, however, the majority of lure potential pollinators are small flies of the family Drosophilidae ( Drosophilidae ) and Nistfliegen ( Milichiidae ). The flowers give off a fragrance that smells like an overripe orange or pineapple. Fruit flies feed on the one hand of fermenting plant materials, on the other hand, they put on such plant constituents and the eggs. Stapelia flavopurpurea so deceiving a potential food source and a suitable place for oviposition before ( "Flying Täuschblume "). The pollinia of Stapelia flavopurpurea are much smaller than other Stapelia species and can thus also through these little flying torn and transported to another flower.
System
The first description of Stapelia flavopurpurea in 1907 by Rudolf Marloth in Volume 18 of the Transactions of the South African Philosophical Society, on page 48, Table 5, Figure 1 The specific epithet flavopurpurea plays on the reddish flower color, forming a shape of this type, of.
