The following terms are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple (that is, the leaf blade or 'lamina' is undivided) or compound (that is, the leaf blade is divided into two or more leaflets). [1] The edge of the leaf may be regular or irregular, and may be smooth or have hair, bristles, or ...
In order to reduce the potential harms of the sawtooth oak, researchers and scientists are advising to remove tree saplings and remove the plant species altogether from reclamation species lists. Due to their preference for well-drained acid soils, Quercus acutissima is able to thrive and survive in various harsh locations. [6]
Cladium (fen-sedge, sawgrass or twig-sedge) is a genus of large sedges, with a nearly worldwide distribution in tropical and temperate regions.These are plants characterized by long, narrow (grass-like) leaves having sharp, often serrated (sawtooth-like) margins, and flowering stems 1–3 m tall bearing a much-branched inflorescence.
The leaves are alternate and palmately compound. First-year plants have palmate leaves with 5 leaflets while second-year plants have palmate leaves with 3 leaflets. Second-year plants develop racemes of flowers each containing 5–20 flowers. [4] The flowers are typically 5-merous with large, white petals and light green sepals, borne in mid ...
Eryngium foetidum is a tropical perennial herb in the family Apiaceae.Common names include culantro (Panama) (/ k uː ˈ l ɑː n t r oʊ / or / k uː ˈ l æ n t r oʊ /), cimarrón, recao (Puerto Rico), chardon béni (France), Mexican coriander, samat, bandhaniya, long coriander, Burmese coriander, sawtooth coriander, Shadow Beni (Caribbean), and ngò gai (Vietnam).
The plant morphologist goes further, and discovers that the spines of cactus also share the same basic structure and development as leaves in other plants, and therefore cactus spines are homologous to leaves as well. This aspect of plant morphology overlaps with the study of plant evolution and paleobotany.

The lanceolate leaves are glossy, simple and alternate and may reach 4 to 12 inches (10–30 cm) long and from 1 to 4 inches (2–10 cm) wide. The leaves have large teeth along the edges (hence the name, sawtooth) to occasionally nearly entire and the tips are pointed. [6]
