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.
Floral diagram of Anagallis arvensis. [1]: 307 The dot represents the main axis, green structure below is the subtending bract. Calyx (green arcs) consists of five free sepals; corolla (red arcs) consists of five fused petals. Antepetalous stamens are joined to petals by hairy filaments.
Stamen is the Latin word meaning "thread" (originally thread of the warp, in weaving). [8]Filament derives from classical Latin filum, meaning "thread" [8]; Anther derives from French anthère, [9] from classical Latin anthera, meaning "medicine extracted from the flower" [10] [11] in turn from Ancient Greek ἀνθηρά (anthērá), [9] [11] feminine of ἀνθηρός (anthērós) meaning ...
Sachs [6] (1873) used them together with floral diagrams, he noted their advantage of being composed of "ordinary typeface". Cassel formula Although Eichler widely used floral diagrams in his Blüthendiagramme , [ 7 ] [ 8 ] he used floral formulae sparingly, mainly for families with simple flowers.
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.
Monodelphous – stamen filaments united as a tube. Poricidal – anthers opening through terminal pores. Staminode – a sterile stamen. Staminodial – (1) concerning a sterile stamen; (2) flowers with sterile stamens. Synandrous – anthers are connected . Syngenesious – anthers are united as a tube; the filaments are free .
The floral axis (receptacle) is the circle in the middle, surrounded by staminodes, petals, and sepals. The main axis is the circle at the top of the diagram [2] 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 ...
[125] [note 1] He identified 24 classes, based mainly on the number, length and union of the stamens. The first ten classes follow the number of stamens directly ( Octandria have 8 stamens etc.), [ 123 ] while class eleven has 11–20 stamens and classes twelve and thirteen have 20 stamens; differing only in their point of attachment.
