It grows on damp and muddy non-calcareous soils. It is found on banks hedges, and tracksides. Taxonomy It was named by William Mitten William Mitten (30 November 1819 – 20 July 1906) was an English people, English pharmaceutical chemist and authority on bryophytes who has been called "the premier bryologist of the second half of the nineteenth century".

List Of Critically Endangered Plants
As of December 2023, the International Union for Conservation of Nature (IUCN) lists 5702 plant species categorized as Critically Endangered, including 569 which are tagged as ''possibly extinct'' and 48 ''possibly extinct in the wild''. 8.6% of all evaluated plant species are listed as critically endangered. The IUCN also lists 284 subspecies and varieties as critically endangered. Additionally 5371 plant species (8.1% of those evaluated) are listed as ''data deficient'', meaning there is insufficient information for a full assessment of conservation status. As these species typically have small distributions and/or populations, they are intrinsically likely to be threatened, according to the IUCN. While the category of ''data deficient'' indicates that no assessment of extinction risk has been made for the taxa, the IUCN notes that it may be appropriate to give them "the same degree of attention as threatened taxa, at least until their status can be assessed."

William Mitten
William Mitten (30 November 1819 – 20 July 1906) was an English people, English pharmaceutical chemist and authority on bryophytes who has been called "the premier bryologist of the second half of the nineteenth century". He built up a collection of some 50,000 specimens of bryophytes (mosses, lichens and liverworts) at his birthplace and home in Hurstpierpoint, Sussex. The collection was largely made up of specimens collected around the world by other collectors and is now at the New York Botanical Garden, having been purchased after his death. These collectors included Richard Spruce and also Alfred Russel Wallace, who became Mitten's son-in-law in 1866. He had four daughters: Annie, the eldest, was the only one to marry; another, Flora, provided assistance in compiling notes for William Edward Nicholson to write a sketch with bibliography on her father.
