Itc. 31. Portion of exhibit at Spring Inspection, 1927, to illustrate the sequence of plant families according to 
Jussieu, 1789 (top row); Bentham and Hooker, 1862-83 (middle row) ; and Engler, 1889-1900 (bottom row). In 
each row the same twenty families are represented, each by a flowering or leafy branch from a plant belonging to 
that family. Note, for example, the different positions of the Magnolia (M). (6200.)
