Duvalia

Duvalia is a genus of succulents in the family Apocynaceae, commonly known as carrion plants. These plants are native to southern Africa. Duvalia species are characterized by their star-shaped, fleshy flowers which often have a foul odor resembling decaying flesh, attracting flies for pollination. The plants themselves are low-growing, typically forming mats or clumps of segmented, fleshy stems.

The stems of Duvalia are thick and cylindrical, often tinged with purple or brown, and can grow to several centimeters in length. They are usually hairless and have a waxy coating. The leaves are greatly reduced or absent, with the stems performing photosynthesis. The flowers emerge from the base of the stems and are typically solitary or borne in small clusters. They usually have five pointed petals and a central corona. Flower colors vary but often include shades of brown, red, or yellow.

Duvalia are adapted to arid conditions and prefer well-draining soil and bright sunlight. They are relatively easy to grow in cultivation and are popular among succulent enthusiasts. Propagation is usually done through stem cuttings or seeds. The genus was named by Adrian Hardy Haworth in honor of Jean-Pierre Duval, a French botanist. Several species are recognized, including Duvalia polita and Duvalia angustifolia, each with slight variations in their floral morphology and growth habit.
