A floral diagram is a graphic representation of the structure of a flower. It shows the number of floral organs, their arrangement and fusion. Different parts of the flower are represented by their respective symbols. Floral diagrams are useful for flower identification or can help in understanding angiosperm evolution.
The labels with darker backgrounds are less common. "V" used by Prenner et al. for the number of ovules per gynoecium is followed by lowercase letter describing the type of placentation. For epicalyx/calyculus, the letter "k" is used. The numbers are inserted after the labels, they may be formatted as sub- or superscript.
ABC model of flower development guided by three groups of homeotic genes. The ABC model of flower development is a scientific model of the process by which flowering plants produce a pattern of gene expression in meristems that leads to the appearance of an organ oriented towards sexual reproduction, a flower.
There are many perfectly identifiable flowers in books like The Book of Hours [11] (two volumes) by the Master of Flowers (Maître-aux-fleurs, 15th century) or Jean Bourdichon's Grandes Heures of Anne of Brittany (between 1503 and 1508), with 337 plants from the Queen's garden, captioned in Latin and French. These artists' objective was, though ...
Quantitative characters are morphological features that can be counted or measured for example a plant species has flower petals 10–12 mm wide. Qualitative characters are morphological features such as leaf shape, flower color or pubescence. Both kinds of characters can be very useful for the identification of plants.
A fleuron (/ ˈ f l ʊər ɒ n,-ə n, ˈ f l ɜːr ɒ n,-ə n / [1]), also known as printers' flower, is a typographic element, or glyph, used either as a punctuation mark or as an ornament for typographic compositions. Fleurons are stylized forms of flowers or leaves; the term derives from the Old French: floron ("flower"). [2]
For example, Helwingia japonica has epiphyllous flowers (ones that form on the leaves). [5] Epiphyte – growing on another organism but not parasitic. Not growing on the ground. Epiphytic – having the nature of an epiphyte. Equinoctial – a plant that has flowers that open and close at definite times during the day.
Plant anatomy or phytotomy is the general term for the study of the internal structure of plants.Originally, it included plant morphology, the description of the physical form and external structure of plants, but since the mid-20th century, plant anatomy has been considered a separate field referring only to internal plant structure.
