THE MARSH LOUSE-WORT, OR TALL RED-RATTLE. (P. palustris, Lin.) 
This species is generally found in marshes, but it also occasionally grows in wet meadows where the soil is 
peaty. It is doubtful whether it is an annual or a perennial, but at any rate it produces its pretty rose- 
coloured flowers in June and July.
