In drawing up the above description use has been made of a manuscript kindly lent by R. Ornduff who has grown this species for comparison with many forms of S. lautus and S. glaucophyllus. Specimens examined include recent collections from Chatham Id: BD 82025 E. A. Madden 1952, and BD 87794 grown by Ornduff from it; BD 87402 J. F. Findlay 1955.
