Cataphyll

The stems of Athrotaxis are covered with small flat pointed leaves called

Acer pseudoplatanus seedling showing cotyledons that supplied the first photosynthetic function for the growing plant. They will soon drop off after the young leaves grow large enough to take over.

Opuntia compressa, showing a so-called spiny cactus. Each areole contains one or more fixed, large spines as well as a sheaf of glochidia. The spines are examples of cataphylls.

In plant morphology, a cataphyll (sometimes also called a cataphyllum, or cataphyll leaf) is a reduced, small leaf. Many plants have both "true leaves" (euphylls) which perform the majority of photosynthesis, and cataphylls that are modified to perform other specialized functions. Cataphylls include bracts, bracteoles, and bud scales, as well as any small leaves that resemble scales, which are known as scale leaves. Some cataphylls have a primary function other than photosynthesis. The functions of cataphylls such as bud scales may be short-lived and they are often shed after the need for them is past.
