Simple inflorescences are the basis for compound inflorescences or synflorescences. The single flowers are there replaced by a simple inflorescence, which can be both a racemose or a cymose one. Compound inflorescences are composed of branched stems and can involve complicated arrangements that are difficult to trace back to the main branch.
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.
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.
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.
[1] [6] The flower stem is known as a pedicel, and those flowers with such a stem are called pedicellate, while those without are called sessile. [7] In the angiosperms, the flowers are arranged on a flower stem as an inflorescence. Just beneath (subtended) the flower there may be a modified, and usually reduced, leaf, called a bract.
Flowering plants usually face evolutionary pressure to optimize the transfer of their pollen, and this is typically reflected in the morphology of the flowers and the behavior of the plants. [54] Pollen may be transferred between plants via several 'vectors,' or methods. Around 80% of flowering plants make use of biotic or living vectors.
3. Sterile flower s, e.g. in Muscari and Leopoldia, at the apex of some inflorescences. 4. A tuft of hairs at the base of some flowers, e.g. in Pfaffia gnaphalioides. 5. A tuft of hairs at the apex or base of some spikelet s. 6. An axil tuft of hairs in inflorescences in some Poaceae, e.g. in Eragrostis comata. commercial name
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.
