Some similarities to : many other Cudweeds such as Jersey Cudweed (Gnapholium luteoalbum), Highland Cudweed (Gnapholium norvegicum), American Cudweed (Gnapholium purpureum), Dwarf Cudweed (Gnapholium supinum), Heath Cudweed (Gnapholium sylvaticum) and Cape Cudweed (Gnapholium undulatum) but Marsh Cudweed is the only one to be found in damp grounds, bare or grassy.

In contradiction to its common name Marsh Cudweed is not a marsh plant, but grows in all sorts of bare damp ground. It is a native and the commonest Cudweed.
