SPERMATOPHYTA. 71 



Salicaria L. Swamp Loosestrife. 



In swamps. Abundant at North Oxford. 

 " The Loosestrife, Lythrum Salicaria, which here waves its purple 

 plumes, is an English plant whose introduction into the valley of the 

 Hudson is a curious chapter in the story of plant distribution. Thirty 

 years ago (about 1870) suddenly, like the lighting of some brilliant 

 tropical bird, appeared on the banks of the Walkill a new plant whose 

 vivid color and graceful habit were at once remarked." See 

 FLINT'S "A Garden of Simples," p. 101.
