* The arrangement of families on the right, left or under side of a framework-family has 
nothing to do with their natural relations; but the printing of names in Roman type shows 
that such families are referable to the same series to which the family in gothic type in the 
middle column belongs; while the names in Italics are those of families assignable to « series 
different from that to which the family in the middle column is referred.
