Polygonum has 200 species scattered over the 
earth; they vary a good deal in the color of their 
flowers and in habit. Two or three of the garden 
species are really handsome annuals, with woody 
perennials and a climber or two, useful in very 
difterent situations viz: where they can be mown 
•around constantly and kept from spreading; and 
again in wild places where they have room to spread 
at will. P. orientale and its white variety are East

places. P. cuspidatum and P. sachalinense are
