Leaf Margins The margin on a leaf is its outside edge. On begonias, they come in a wide range of variously accented margins. A leaf with no dentation or indivisions is called entire. All possible margins have been illustrated on the following pages. Many times margins can also be a combination of one or more types of margins so require combining descriptions to properly describe. For instance if a leaf is serrated with hairs along the edge you would combine serrate (serrated edge) and ciliate (hairy edge) as serrate ciliate margin. The next few pages have illustrations combined with the exact description of the term. Crenulate: A crenulate margin is minutely crenate. That means it has a scalloped edge but the scallops are very small and fine. Double serrate: A double serrate margin is a serrated margin that also has extra serration on the teeth of the serration. Entire: An entire margin is a margin with a bare edge with no indentations or divisions along the margin. A margin with extremely slight waviness or slight uneveness should still be described as entire. Crenate: A crenate margin is a margin with obtuse or broad rounded teeth or scallops. page 17
Serrate: A serrate margin is a margin with sharp saw like teeth that slant towards the apex or tip of the leaf. Denticulate: A denticulate margin is a minutely dentate margin. It is similar to dentate in that the points are upright along the margin but are finer than dentate. Repand: A repand margin is a margin with an unevenly slightly sinuous edge. page 18 Ciliate: A ciliate margin is a margin with small hairs along the edge. Serrulate: A serrulate margin is a minutely serrate edge. Similar to serrate but the teeth are smaller.
