Diagram of flower parts. In botany, floral morphology is the study of the diversity of forms and structures presented by the flower, which, by definition, is a branch of limited growth that bears the modified leaves responsible for reproduction and protection of the gametes, called floral pieces.
The morphology of a flower, or its form and structure, ... [123] while class eleven has 11–20 stamens and classes twelve and thirteen have 20 stamens; ...
In the 19th century, two contrasting methods of describing the flower were introduced: the textual floral formulae and pictorial floral diagrams. [2] Floral diagrams are credited to A. W. Eichler, whose extensive work Blüthendiagramme [3] [4] (1875, 1878) remains a valuable source of information on floral morphology.
One important and unique event in plant morphology of the 21st century was the publication of Kaplan's Principles of Plant Morphology by Donald R. Kaplan, edited by Chelsea D. Specht (2020). [36] It is a well illustrated volume of 1305 pages in a very large format that presents a wealth of morphological data.
Heterostyly is a unique form of polymorphism and herkogamy in flowers. In a heterostylous species, two or three morphological types of flowers, termed "morphs", exist in the population. On each individual plant, all flowers share the same morph. The flower morphs differ in the lengths of the pistil and stamens, and
In order to explain the floral morphology of the Liliaceae, van Tunen et al. proposed a modified ABC model in 1993. This model suggests that class B genes are not only expressed in verticils 2 and 3, but also in 1. It therefore follows that the organs of verticils 1 and 2 express class A and B genes and this is how they have a petaloid structure.
Satyrium carneum.Ground orchid with typical zygomorphic floral anatomy. Zygomorphic ("yoke shaped", "bilateral" – from the Greek ζυγόν, zygon, yoke, and μορφή, morphe, shape) flowers can be divided by only a single plane into two mirror-image halves, much like a yoke or a person's face.
Floral diagramming is a method used to graphically describe a flower. In the context of floral diagramming, the floral axis represents the center point around which the diagram is oriented. [ 3 ] The floral axis can also be referred to as the receptacle in floral diagrams or when describing the structure of the flower. [ 4 ]
