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.

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 daisy-like flowers are purplish with a yellow centre, about 7 mm (0.28 in) across, ligules 1.5–2.5 mm (0.059–0.098 in) long. Flowering occurs mostly from November to May and the fruit is a wedge-shaped, flattened cypsela , ribbed and about 5 mm (0.20 in) long.

The heads or daisy-like "flowers" are arranged singly in leaf axils or on the ends of short side branchlets and are 5–10 mm (0.20–0.39 in) in diameter and more or less sessile, with five or six rows of bracts forming an involucre 3.5–5 mm (0.14–0.20 in) long at the base.

[1] A floral formula is often used along with a floral diagram.
