The calyx is usually connected to the bottom via a stem. The stem is either circular or pentagonal (five-sided) in section and composed of numerous disc-like plates called columnals. Stemmed forms frequently have a holdfast composed of small, polygonal plates, although some species wrapped their stem around other organisms, and thus didn't need a holdfast.
