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
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 ...
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. [4]
See also Leaf shape. acropetal Moving from roots to leaves, e.g. of molecular signals in plants. acrophyll Regular leaves of a mature plant, produced above the base, as opposed to bathyphyll. acrostichoid (describing a type of sorus) Covering the entire abaxial surface of a frond, usually densely so, as in Elaphoglossum and Acrostichum. actino-
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.
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 ...
Prickles on a blackberry branch. In plant morphology, thorns, spines, and prickles, and in general spinose structures (sometimes called spinose teeth or spinose apical processes), are hard, rigid extensions or modifications of leaves, roots, stems, or buds with sharp, stiff ends, and generally serve the same function: physically defending plants against herbivory.
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.
