All teachers of botany are familiar with floral diagrams as used in systematic treatises, and most of us have proved their value along educational lines. Considerable diversity exists, however, as to their use and method of construction, and after several years’ experience in actual class work I have attempted to organize the subject in the hope of increasing their educational value. In 1819 Turpin1 devised the first floral diagram to explain the structure of the flower in grasses, the horizontal form alone being used. (Figure 1.) Later this method was largely employed by D-e Candolle, and since then such diagrams have been freely used, e. g. in the systematic works of Le Maout and De Caisne2 and of t-Hchler,3 in the wall charts of Henslow4 and of Peter5, and in textbooks, both foreign and American.
