Plants in the family Urticaceae, also known as Stinging Nettles, also form leaf cystoliths, but only during their later flowering and seed setting stages.
Four ships of the Royal Navy have borne the name HMS Nettle, after the stinging nettle, a species of flowering plants.
In western Europe the Marsh Warbler breeds mainly in rank vegetation on damp or seasonally flooded soils, and is particularly attracted to tall herbaceous vegetation such as nettles, meadowsweet, willowherbs and to young osiers and other low woody plants.
They prefer willow and poplar, but have also been recorded on alder, birch, blueberry, Shepherdia canadensis, cherry, elder, raspberry, Amelanchier species, stinging nettle and Viburnum species
