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 ...
External leaf characteristics, such as shape, margin, hairs, the petiole, and the presence of stipules and glands, are frequently important for identifying plants to family, genus or species levels, and botanists have developed a rich terminology for describing leaf characteristics. Leaves almost always have determinate growth.
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-
Leaf Base Shape: Semiamplexicaul – the leaf base wraps around the stem, but not completely. Leaf Blade Apex: Acuminate – narrowing to a point (a term used for other structures, too). Acute – with a sharp, rather abrupt ending-point. Acutifolius – with acute leaves. Attenuate – tapering gradually to a narrow end. Leaf Blade Margins:
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.
Magnolia grandiflora, a spiraled flower.. Depending on the family considered, the pieces of the flower can be arranged on the receptacle in two different ways. In the case of the spiral arrangement, the parts are inserted consecutively and at different levels, describing a spiral on the axis in the same way as the leaves are inserted on the stem.
To shape plants, trim back any disproportionately long shoots, cutting back to a leaf or side branch. Lower branches can be shortened to maintain a more upright growth habit. How To Get Early ...
A plant morphologist makes comparisons between structures in many different plants of the same or different species. Making such comparisons between similar structures in different plants tackles the question of why the structures are similar. It is quite likely that similar underlying causes of genetics, physiology, or response to the ...
