käpylisäke

The term "käpylisäke" is a Finnish word that translates to "pinecone scale" in English. It refers to the individual, woody structure that makes up a pinecone. These scales are typically arranged in a spiral pattern around the central axis of the cone and are responsible for protecting the developing seeds within.

Each käpylisäke usually has a thickened base and a thinner, often slightly curved or pointed, free end. The size, shape, and texture of käpylisäke can vary significantly between different species of pine trees, serving as a characteristic feature for identification. For example, some scales are smooth, while others may have a spiny or warty surface. The number of scales on a single pinecone can also range from a few dozen to over a hundred, depending on the species.

When a pinecone matures, the käpylisäke will typically open to release the seeds, often facilitated by changes in humidity. This release mechanism ensures the dispersal of the pine tree's offspring. In some species, the scales may remain attached to the cone even after opening, while in others, they may fall off gradually. The dried käpylisäke are a common sight in forests where pine trees grow and are often collected by nature enthusiasts.
