Mediocalcar decoratum is an unusual miniature, mat-forming species from the island of New Guinea. It is cool growing and does well either on a mount or in a pot, but needs room to ramble. The individual growths are about 1 cm, have a thick fleshy stem and a fan of four tiny fleshy leaves at the top. Each new growth begins near the top of the previous growth, forming an ever-lengthening chain. The flowers, .5 cm in size, come from the base of the growths and look like tiny candy-corns.
