Dr. Schlechter (in Hngl. Jahrb, xxi. Beibl. 54, 11) refers S. tetrapterum, Turez., 
to this plant. I have not seen Turczaninow’s type, but according to his description 
it should rather belong to Cynanchum sarcoste toides, where I have referred it 
in this work. See note under that species concerning Thunberg’s localities.
