A variable species, but without question many of its so-called 

 varieties are due to crossing with S. Telephium. The plant, when 

 typical, is known at once from 5. Telephium, to which it is closely 

 allied, by its greenish flowers and very broad, slightly toothed dark- 

 green opposite leaves. Variation in the large series of garden forms 

 which I have examined is mostly in the direction of S. Telephium. 

 In my garden I grew for some years the purpureum form of S. Telephium, 

 which seeded freely and kept constant. Later I introduced typical 

 S. maximum, collected by the Baltic, near Danzig, where it also showed
