THE 

 PINK PEESICAEIA. 



Polygonum Perslcaria. Nat. Ord., 

 Polygonacece. 



HE Polygonum Persicaria, pink 

 persicaria, or, as it is sometimes 

 called, the spotted persicaria, is 

 very frequently met with on 

 waste ground, in gardens, and by 

 the roadside, and is more par- 

 ticularly abundant when such 

 localities are somewhat damp and 

 low-lying. It is an annual, but 

 ^ seeds freely, and our readers will 

 have but little difficulty in finding 

 specimens. Its small and insig- 

 nificant-looking blossoms are met 

 with from July to October. Eleven 

 to fifteen species of polygonum are 

 reckoned as indigenous to Britain, the 

 difference in the number being, as we have seen 

 in the case of several other plants, the result 

 of the greater or less importance attributed 

 to certain modifications and differences of structures 

 differences that appear to some botanists sufficiently 

 distinct and permanent to justify their giving them
