A stringency is the property of Ly thrum Salicariay which is 

 reputed to have been found useful in inveterate diarrhoeas ; 

 another species of the same genus is reputed, in Mexico, to be 

 astringent and vulnerary. The flowers of Lythrum Hunteri are 

 employed in India, mixed with Mortnda, for dyeing, under the 

 name of Dhawry. The Mexicans consider Hernia salicifoUa
