Plant habit refers to the overall shape of a plant, and it describes a number of components such as stem length and development, branching pattern, and texture. While many plants fit neatly into some main categories, such as grasses, vines, shrubs, or trees, others can be more difficult to categorise.
Three goals of plant taxonomy are the identification, classification and description of plants. The distinction between these three goals is important and often overlooked. 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.
It can be useful for flower identification or comparison between angiosperm taxa. Paleontologists can take advantage of diagrams for reconstruction of fossil flowers. Floral diagrams are also of didactic value. [1]: xiii Relation of a plant material (Campanula medium) to the floral diagram. Black dashed line shows the cross-section. 1 ...
The pattern of branching in a tree will vary from species to species, as will the appearance of a plant as a tree, herb, or grass. Fourthly, plant morphology examines the pattern of development , the process by which structures originate and mature as a plant grows.
Leaves of most plants include a flat structure called the blade or lamina supported by a network of veins, a petiole and a leaf base; [1] but not all leaves are flat, some are cylindrical. [ citation needed ] Leaves may be simple, with a single leaf blade, or compound, with several leaflets .
Diagram of flower parts. In botany, floral morphology is the study of the diversity of forms and structures presented by the flower, which, by definition, is a branch of limited growth that bears the modified leaves responsible for reproduction and protection of the gametes, called floral pieces.
Branching, with branches having unequal diameters, such as a trunk and its branch. Contrast isotomic. annual A plant that completes its life cycle (i.e. germinates, reproduces, and dies) within a single year or growing season. annulus 1. A ring-like structure; in the form of a ring.
The leaf lobes of Grevillea rivularis are described as divaricate. [2]In botany, the term is often used to describe the branching pattern of plants.Plants are said to be divaricating when their growth form is such that each internode diverges widely from the previous internode, producing an often tightly interlaced shrub or small tree.
