There is no agreement on how floral diagrams should be drawn, it depends on the author whether it is just a rough representation, or whether structural details of the flower are included.ĭiagrams can describe the ontogeny of flowers, or can show evolutionary relationships. The diagram may also include symbols that don’t represent physical structures, but carry additional information (e.g. Different organs are represented by distinguishable symbols, which may be uniform for one organ type, or may reflect concrete morphology.

It usually shows the number of floral parts, their sizes, relative positions and fusion. It may be also defined as “projection of the flower perpendicular to its axis”. Floral Diagrams (2010) by Ronse De Craene followed Eichler’s approach using the contemporary APG II system.īasic characteristics and significance Ī floral diagram is a schematic cross-section through a young flower. Organogenesis of Flowers by Sattler (1973), Botanische Bestimmungsübungen by Stützel (2006) or Plant Systematics by Simpson (2010). They were used in different textbooks, e.g. in Types of Floral Mechanism by Church (1908). Eichler inspired later generation of scientists, including John Henry Schaffner. Eichler, his extensive work Blüthendiagramme (1875, 1878) remains a valuable source of information on floral morphology. In the 19th century, two contrasting methods of describing the flower were introduced: the textual floral formulae and pictorial floral diagrams.
