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 branch of the flower that joins the floral parts to the stem is a shaft called the pedicel, which normally dilates at the top to form the receptacle in which the various floral parts are inserted. All spermatophytes ("seed plants") possess flowers as defined here (in a broad sense), but the internal organization of the flower is very ...
A plant morphologist makes comparisons between structures in many different plants of the same or different species. Making such comparisons between similar structures in different plants tackles the question of why the structures are similar. It is quite likely that similar underlying causes of genetics, physiology, or response to the ...
Floral biology is an area of ecological research that studies the evolutionary factors that have moulded the structures, behaviours and physiological aspects involved in the flowering of plants. The field is broad and interdisciplinary and involves research requiring expertise from multiple disciplines that can include botany, ethology ...
Corymb – a grouping of flowers where all the flowers are at the same level, the flower stalks of different lengths forming a flat-topped flower cluster. Cyme – is a cluster of flowers where the end of each growing point produces a flower. New growth comes from side shoots, and the oldest and first flowers to bloom are at the top.
There are 27 families of flowering plants whose earliest ancestors diverged from what became the two most prominent groups of flowering plants, the eudicots and monocots. [1] [a] They are quite diverse, with woody and non-woody plants, evergreen and deciduous shrubs and trees, and plants that grow in soil, in water and on other plants.
Floral formulae are one of the two ways of describing flower structure developed during the 19th century, the other being floral diagrams. [2] The format of floral formulae differs according to the tastes of particular authors and periods, yet they tend to convey the same information. [1] A floral formula is often used along with a floral diagram.
Schemes and floral diagrams of the different floret types of the Asteraceae: Leucanthemum vulgare: a = disc flower; b = ray flower. 1 – style with stigmas 2 – anthers 3 – corolla ; typically, in the ray flower, three petals are joined to form a strap (in other species, five petals can fuse to form a ligule) 4 – reduced calyx
