Cataphyll

The stems of Athrotaxis are covered with small flat pointed leaves called "scale leaves" or "cataphylls".

In plant morphology, a cataphyll (sometimes also called a cataphyllum[1] or cataphyll leaf[2]) is a reduced, small leaf.[3] Many plants have both "true leaves" (euphylls), which perform most of the photosynthesis, and cataphylls, which are modified to perform other functions.[4]

Cataphylls include bracts, bracteoles and bud scales, as well as any small leaves that resemble scales, known as scale leaves.[5] The functions of cataphylls, such as bud scales, may be short-lived, and they are often shed after their function is fulfilled.[6]
