I was given a house plant which was called the Rosary Vine -ceropegia woodi but it does not resemble any of the google images. Measuring at about 10 inches long the "vine" consists of spear- tall heart shaped leaves folded down the center and crumpled or twisted...the leaves are so densely on the stem you cannot even see the stem. The leaves have a very shiny darker green side and a lighter matte green underside. When the stem is cut it gives off a clear mucus ( aloe-like) Can anyone help me identify this plant!?
