A geophyte (earth+plant) is a plant with an underground storage organ including true bulbs, corms, tubers, tuberous roots, enlarged hypocotyls, and rhizomes. Most plants with underground stems are geophytes but not all plants that are geophytes have underground stems. Geophytes are often physiologically active even when they lack leaves.
Homeria species produce bunches of cormels on underground stem nodes, and Watsonia meriana for example actually produces cormels profusely from under bracts on the inflorescences. [4] Those growing from the bottom of the corm are normal fibrous roots formed as the shoots grow, and are produced from the basal area at the bottom of the corm.
Some plants have rhizomes that grow above ground or that lie at the soil surface, including some Iris species as well as ferns, whose spreading stems are rhizomes. Plants with underground rhizomes include gingers, bamboo, snake plant, the Venus flytrap, Chinese lantern, western poison-oak, [13] hops, and Alstroemeria, and some grasses, such as ...
In most plants, stems are located above the soil surface, but some plants have underground stems. Stems have several main functions: [3] Support for and the elevation of leaves, flowers, and fruits. The stems keep the leaves in the light and provide a place for the plant to keep its flowers and fruits.
In botany, stolons are plant stems which grow at the soil surface or just below ground that form adventitious roots at the nodes, and new plants from the buds. [1] [2] Stolons are often called runners. Rhizomes, in contrast, are root-like stems that may either grow horizontally at the soil surface or in other orientations underground. [1]
The stems of dendrobium orchids are thick pseudobulbs that store water and nutrients and should not be cut after blooming. With such a diverse plant family, I encourage home growers to try new ...
The purpose of a pangram is for fun wordplay, for artists to display various fonts in sentences using every letter, and they are useful to children that are learning to write, practice their ...
A rhizome is a horizontal stem that often grows underground, usually sending out roots and shoots from its nodes. Some plants have rhizomes that grow above ground or that lie at the soil surface, including some Iris species. Usually, rhizomes have short internodes; they send out roots from the bottom of the nodes and new upward-growing shoots ...
