Being one of the more visible features, leaf shape is commonly used for plant identification. Similar terms are used for other plant parts, such as petals, tepals, and bracts. Oddly pinnate, pinnatifid leaves (Coriandrum sativum, coriander or cilantro) Partial chlorosis revealing palmate venation in simple leaves of Hibiscus mutabilis
A leaf (pl.: leaves) is a principal appendage of the stem of a vascular plant, [1] usually borne laterally above ground and specialized for photosynthesis.Leaves are collectively called foliage, as in "autumn foliage", [2] [3] while the leaves, stem, flower, and fruit collectively form the shoot system.

Used for leaf fungus that live on the surface of the leaf. Epiphloedal – growing on the bark of trees. Epiphloedic – an organism that grows on the bark of trees. Epiphyllous – growing on the leaves. For example, Helwingia japonica has epiphyllous flowers (ones that form on the leaves). [5] Epiphyte – growing on another organism but not ...
The primary leaf or leaves of a plant embryo which upon germination develops into the seed-leaf or the first set of leaves. craspedodromous Pinnate venation in which the secondary veins terminate at the margin s, often as teeth. crateriform In the shape of a saucer or shallow cup; hemispherical or more shallow. cremnophyte
For example, the leaves of pine, oak, and cabbage all look very different, but share certain basic structures and arrangement of parts. The homology of leaves is an easy conclusion to make. 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 ...
This is an incomplete list of plants with trifoliate leaves. Trifoliate leaves (also known as trifoliolate or ternate leaves) are a leaf shape characterized by a leaf divided into three leaflets. Species which are known to be trifoliate are listed here.
In botany, a rosette is a circular arrangement of leaves or of structures resembling leaves. In flowering plants, rosettes usually sit near the soil. Their structure is an example of a modified stem in which the internode gaps between the leaves do not expand, so that all the leaves remain clustered tightly together and at a similar height.
In botany, a stipule is an outgrowth typically borne on both sides (sometimes on just one side) of the base of a leafstalk (the petiole).Stipules are considered part of the anatomy of the leaf of a typical flowering plant, although in many species they may be inconspicuous —or sometimes entirely absent, and the leaf is then termed exstipulate.
