The "flowers" of P. cynaroides are actually composite flower heads (termed an inflorescence) with a collection of flowers in the centre, surrounded by large colourful bracts, from about 120 to 300 millimetres (5 to 12 in) in diameter. Large, vigorous plants produce six to ten flower heads in one season, although some exceptional plants can ...
A flower, also known as a bloom or blossom, is the reproductive structure found in flowering plants (plants of the division Angiospermae).Flowers consist of a combination of vegetative organs – sepals that enclose and protect the developing flower.
For example, male inflorescence in plants often produce more flowers than females . Furthermore, pollen export and ultimately paternity, often increases with flower number, even for plants with hermaphroditic flowers. Retention of older flowers with no pollinator rewards can lead to increased pollinator visitation rate and increased pollen removal.

Examples of this type of orchids are the species Bonatea speciosa, Habenaria epipactidea, the genus Satyrium, Disa cooperi and D. ophrydea.

Even in his early years, Linnaeus seemed to have a liking for plants, flowers in particular. Whenever he was upset, he was given a flower, which immediately calmed him. Nils spent much time in his garden and often showed flowers to Linnaeus and told him their names. Soon Linnaeus was given his own patch of earth where he could grow plants. [20]
The flower varies in shape from an open cup to a narrow hanging tube. In the species the flowers are mainly in shades of yellow through orange to red. The flowers are arranged in umbels (i.e. the flower-stalks or pedicels radiate from a single point); each umbel has a long stalk or peduncle. Several bracts subtend the umbels.
