Stamens, with distal anther attached to the filament stalk, in context of floral anatomy. Depending on the species of plant, some or all of the stamens in a flower may be attached to the petals or to the floral axis. They also may be free-standing or fused to one another in many different ways, including fusion of some but not all stamens.
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.
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 cowslip (Primula veris) has two kinds of flowers in nearly equal proportions: in the one the stamens are long and the style short, and in the other the reverse, so that in one the stamens are visible at the mouth of the tube of the flower, in the other the stigma occupies the same place, while the stamens are halfway down the tube. The ...
Anatomy of a flower. A flower's anatomy, as defined by the presence of a series of organs (sepals, petals, stamens and carpels) positioned according to a given pattern, facilitate sexual reproduction in flowering plants. The flower arises from the activity of three classes of genes, which regulate floral development: [8]
K 3+3 – a calyx with six free sepals, arranged as two separate whorls; A∞ – many stamens; P3–12 – perianth from three to twelve petals; Groups of organs can be described by writing the number of instances in the group as superscript. A5² – 5 groups of 2 stamens. The formula can also express organ fusion.
A bundle or structure of stamens forming one unit in an adelphous flower; for example, the stamen tube around the pistil of Hibiscus. adelphous Having organs, particularly filament s such as stamen s, connected into one or more adelphiae, whether in the form of bunches or tubes, such as is commonly seen in families such as Malvaceae. Usage of ...
Corolla – the whorl of petals of a flower. Corona – an additional structure between the petals and the stamens. Disk – an enlargement or outgrowth from the receptacle of the flower, located at the center of the flowers of various plants. The term is also used for the central area of the head in composites where tubular flowers are attached.
