OL' tbe Trhtieht Section, this is a quite distinct species, very much shorter 

 and smaller than its allies, S, panicaulis, L\ Muel!., alone approaching it in 

 size. Our plant is indeed considerably smaller than that species, which also 

 has gradually tapering, acuminate leaves, much more distantly toothed ; 

 S, tnstlcliellus, Besch., is also much taller, with leaves almost of S. fristlcJius.
