The flat and very curious flowers are carried by a peduncle of 4 to 5 cm. It forms a beautiful waxy and leathery star, yellow speckled with brown, 6 to 8 cm in diameter. The sexual parts are extremely modified: the center of the flower presents a crown in the center of which is located the stigma .
Pollen is divided into pollinia as in orchids. They are well-protected beneath the crown. It requires strong mechanical force to be moved to fertilize the flower. This is normally done by insects. Flies are indeed attracted by this enchanting flower its scent and colors tend to be like those of meat that has been spoiled.
Luckily Stapelia variegata does not appear to be particularly fragrant when compared with other Stapelia.

They are flat with bristles that allow the seeds to disperse by winds.
How do I get my star cactus to bloom?
There are many reasons you might be longing to see a star-shaped bloom on your cactus, but the best way to make it happen is to give it what it wants.
There are a number of things you can do to encourage flowering in your plant, but they all begin with one key element: direct morning light. With regular waterings (making sure the soil dries out in between) and a diluted nitrogen-rich fertilizer during the summer, you can give your cactus the best chance of blooming.

The ideal time of day for photosynthesis is usually in the morning, so place your cactus where it gets direct light in the mornings if possible. You may even consider moving it outside during the summer months and bringing it back in before bedtime (if you live in an area with mild temperatures).
