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 S. 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
