翡翠玉 Mabel Buttons (Conophytum calculus)

Conophytum calculus is a small South African species of succulent plant in the family Aizoaceae.Rounded ball-shaped succulent plant, that divides to form dense clumps.The ball shape is formed from the plant's leaf-pair having fused entirely, leaving only a tiny slit at the top, where the flower and the succeeding leaf pair pushes through. The new leaf-pair forms inside the ball. When it is ready, the ball of the old leaf-pair shrivels and dries out, before it is split open by the new leaf-pair ball.Nocturnal floweer are golden yellow to dark orange.
