The age of some herbaceous perennial plants can be determined by herbchronology, the analysis of annual growth rings in the secondary root xylem. [18] Herbaceous plants do not produce perennializing above-ground structures using lignin, which is a complex phenolic polymer deposited in the secondary cell wall of all vascular plants. The ...
The word herbaceous is derived from Latin herbāceus meaning "grassy", from herba "grass, herb". [9] Another sense of the term herb can refer to a much larger range of plants, [10] with culinary, therapeutic or other uses. [6]
A prefix meaning "two", e.g. bisulcate, having two sulci or grooves. biennial A plant which completes its life cycle (i.e. germinates, reproduces, and dies) within two years or growing seasons. Biennial plants usually form a basal rosette of leaves in the first year and then flower and fruit in the second year. bifid
Each plant commences its growth as a herbaceous plant. Plants that remain herbaceous are shorter and seasonal, dying back at the end of their growth season. Woody plants (such as trees, shrubs and woody vines will gradually acquire woody (lignaceous) tissues, which provide strength and protection for the vascular system, [4] and they tend to be ...
Deciduous perennials include herbaceous and woody plants; herbaceous plants have stems that lack hard, fibrous growth, while woody plants have stems with buds that survive above ground during dormancy. [15] Some perennials are semi-deciduous, meaning they lose some of their leaves in either winter or summer. [16]
Extant ferns are herbaceous perennials and most lack woody growth. [5] When woody growth is present, it is found in the stem. [6] Their foliage may be deciduous or evergreen, [7] and some are semi-evergreen depending on the climate. [8] Like the sporophytes of seed plants, those of ferns consist of stems, leaves and roots.
The Fabaceae (/ f ə ˈ b eɪ s i. iː,-ˌ aɪ /) or Leguminosae, [6] commonly known as the legume, pea, or bean family, are a large and agriculturally important family of flowering plants. It includes trees, shrubs, and perennial or annual herbaceous plants, which are easily recognized by their fruit and their compound, stipulate leaves.
The scientific use of life-form schemes emphasizes plant function in the ecosystem and that the same function or "adaptedness" to the environment may be achieved in a number of ways, i.e. plant species that are closely related phylogenetically may have widely different life-form, for example Adoxa moschatellina and Sambucus nigra are from the ...
