The “Missouri Masonic Family” tree below shows the bewildering number of rites and degrees in America. As a branch to the York Rite (left) there are three degrees that appear to have crossed swords in a triangle without a star as emblem: Super Excellent Master, Secret Master, Royal Master. To the right you see the same image, but within a star which says “Knight Masons” below.
