Palae

Palae, also known as palea, is a term used in botany to describe the lower glume of a grass seed. The upper and lower glumes are a pair of bracts that enclose the floret of a grass spikelet. The palae is usually narrower and more pointed than the upper glume, known as the lemma.

The palae is a distinctive feature of grass anatomy and is often used in botanical classifications. It can be used to identify different species of grasses, as the shape and structure of the palae can vary significantly between different genera and species.

In addition to its role in taxonomy, the palae also serves a functional purpose. The glumes, including the palae, help to protect the seed and facilitate its dispersal by wind. The shape and size of the glumes can affect the aerodynamics of the seed, allowing it to travel further and more efficiently.

The study of grass anatomy, including the palae, is an important area of research in botany and ecology. Grasses are a key component of many ecosystems, and an understanding of their structure and function can provide valuable insights into the workings of these systems. By studying the palae and other features of grass anatomy, scientists can gain a better understanding of the biology of grasses and their role in the environment.
