An order of pleurocarpous mosses which range in size from minute to large. The primary stems are creeping, with secondary stems prostrate to ascending, irregularly branched to regularly 1- to 3-pinnate. The leaves are typically ovoid, nerveless or with a short double nerve or a single nerve ending below the leaf tip. There are several genera, found in a wide range of habitats. Thuidium tamariscinum is a very attractive moss, bright green in colour, and intricately, tripinnately branched to give a fern-like appearance. It is a common and conspicuous moss in woods and on shady banks.
