neglecta from S. media on morphological grounds alone is difficult. In Britain, Whitehead and Sinha found that specimens with ten perfect stamens, petals more or less equalling the sepals, and growing on the margins of streams, lakes or other damp places, were assignable to S. neglecta. While S. neglecta usually has ten stamens, S. media may have as few as 3−7. Other differences are that S. neglecta is invariably found as a ruderal in damp conditions, while S. media also occurs as a weed, in a variety of habitats, including cultivated ground; and S. neglecta flowers only between April and July, while S. media flowers throughout the year.
