About Stratiotes aloides L.
Stratiotes aloides L. forms tufted rosettes of lanceolate, serrated leaves that grow up to 30 cm long. It produces white flowers up to 45 mm across in summer; male plants bear flowers with many stamens. This species occurs in shallow waters of Ireland, where it was introduced, and is apparently now extinct in north-east Ireland. It is rare in east England. It is most suited for cultivation in cool aquariums or outdoor ponds. It can be propagated from runners that grow from the center of the leaf rosette. This herb has long held a high reputation for treating wounds, particularly wounds caused by iron tools, and is applied externally. The plant is also said to be useful for treating ergotism and bruised kidneys.
