five types of leaf margins?

Answer 1

The leaf margin is characteristic for a genus and aids in determining the species.

* entire: even; with a smooth margin; without toothing
* ciliate: fringed with hairs
* crenate: wavy-toothed; dentate with rounded teeth, such as Fagus (beech)
* dentate: toothed, such as Castanea (chestnut)
coarse-toothed: with large teeth
glandular toothed: with teeth that bear glands.
* denticulate: finely toothed
* doubly toothed: each tooth bearing smaller teeth, such as Ulmus (elm)
* lobate: indented, with the indentations not reaching to the center, such as many Quercus (oaks)
palmately lobed: indented with the indentations reaching to the center, such as Humulus (hop).
* serrate: saw-toothed with asymmetrical teeth pointing forward, such as Urtica (nettle)
* serrulate: finely serrate
* sinuate: with deep, wave-like indentations; coarsely crenate, such as many Rumex (docks)
* spiny: with stiff, sharp points, such as some Ilex (hollies) and Cirsium (thistles).

Answer 2

Types Of Leaf Margins

Answer 3

There are generally 3 types of leaf margins: entire, toothed, and lobed. Entire leaves are smooth, they have no bumps (like a dogwood tree leaf). Toothed leaves have shallow bumps, like on a birch tree. There are seval sub-types of toothed (see web site below) including doubly-toothed). Lobed leaves have deep indentations (like on an oak leaf).
