PHYLLARIES Meaning and
Definition
-
Phyllaries are specialized leaf-like structures found in the outermost layer of certain flowers, particularly those in the daisy or sunflower family (Asteraceae).
These characteristic structures are often arranged in overlapping layers around the base of the flower head, protecting the developing flower buds before they open. Phyllaries are typically small and narrow, resembling bracts or modified leaves, and they can vary in shape, size, and number depending on the species.
The phyllaries serve several important functions. Firstly, they provide protection to the developing flower buds, shielding them from damage caused by external factors such as harsh weather conditions, predators, or pathogens. Secondly, they play a role in attracting pollinators. The color, shape, and texture of phyllaries can sometimes mimic petals, contributing to the overall appearance of the flower head and attracting pollinators towards the center, where the actual reproductive structures are located. Finally, phyllaries also provide structural support to the flower head, helping to maintain its shape and integrity.
In addition to their functional roles, the presence or absence of phyllaries and their characteristics can serve as important identification features in the classification and taxonomy of plants within the Asteraceae family. They are often used by botanists and horticulturists to distinguish between different species and genera.

Etymology of PHYLLARIES
The word "phyllaries" has its etymology rooted in the Greek language. It is derived from the Greek word "phullon", meaning "leaf". The term "phyllaries" specifically refers to the involucral bracts that surround the base of a flower head in plants of the Asteraceae family (also known as the composite or daisy family). These bracts often resemble leaves, hence the use of "phyllaries" to describe them.
