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 ...
The plants had tapering trunks as wide as 2 m (6.6 ft) at their base that rose to about 40 m (130 ft) [2] and even 50 m (160 ft), [1] arising from an underground system of horizontally spreading branches that were covered with many rootlets.
Plant identification is a determination of the identity of an unknown plant by comparison with previously collected specimens or with the aid of books or identification manuals. The process of identification connects the specimen with a published name. Once a plant specimen has been identified, its name and properties are known.
The leaves of tricussate plants such as Nerium oleander form a triple helix. The leaves of some plants do not form helices. In some plants, the divergence angle changes as the plant grows. [22] In orixate phyllotaxis, named after Orixa japonica, the divergence angle is not constant. Instead, it is periodic and follows the sequence 180°, 90 ...
Duration of leaves: Deciduous – leaves are shed after the growing season. Evergreen – leaves are retained throughout the year, sometimes for several years. Fugacious – lasting for a short time: soon falling away from the parent plant. Marcescent – dead leaves, calyx, or petals are persistent and retained. Persistent – see Marcescence ...

This is noticeable in the outline, shape, and hairiness of its leaves, in the size of the lower leaves, in the number of stamens, and in the size of the seeds and fruits. [3] M. perennis possesses three distinct varieties are: M. perennis L. var. genuina Miiller-Aarg
