Herbaceous: Non woody stems which die at the end of the growing season. Internode: An interval between two successive nodes. It possesses the ability to elongate, either from its base or from its extremity depending on the species.
Lysimachia latifolia (broadleaf starflower) is a perennial herbaceous plant of the ground layer of forests in western North America. Herbaceous plants are vascular plants that have no persistent woody stems above ground. [1] [2] This broad category of plants includes many perennials, and nearly all annuals and biennials. [3]
Pedicel – the stem or stalk that holds a single flower in an inflorescence. Peduncle – the part of a stem that bears the entire inflorescence, normally having no leaves, or the leaves having been reduced to bracts. When the flower is solitary, it is the stem or stalk holding the flower. Peduncular – referring to or having a peduncle.
Bark is present only on woody plants - herbaceous plants and stems of young plants lack bark. Tree cross section diagram. From the outside to the inside of a mature woody stem, the layers include the following: [20] Bark Periderm Cork (phellem or suber), includes the rhytidome; Cork cambium (phellogen) Phelloderm; Cortex; Phloem; Vascular ...
A caudex (pl.: caudices) of a plant is a stem, [1] but the term is also used to mean a rootstock [2] and particularly a basal stem structure from which new growth arises. [ 3 ] In the strict sense of the term, meaning a stem, "caudex" is most often used with plants that have a different stem morphology from the typical angiosperm dicotyledon ...
The cork cambium is a lateral meristem and is responsible for secondary growth that replaces the epidermis in roots and stems. It is found in woody and many herbaceous dicots, gymnosperms and some monocots (monocots usually lack secondary growth). It is one of the plant's meristems – the series of tissues consisting of embryonic disk ...
In the roots of vascular plants, the cortex occupies a larger portion of the organ's volume than in herbaceous stems. The loosely packed cells of root cortex allow movement of water and oxygen in the intercellular spaces. [4] One of the main functions of the root cortex is to serve as a storage area for reserve foods. [4]
In botany and dendrology, a rhizome (/ ˈ r aɪ z oʊ m / RY-zohm) [note 1] is a modified subterranean plant stem that sends out roots and shoots from its nodes. Rhizomes are also called creeping rootstalks or just rootstalks. [3] Rhizomes develop from axillary buds and grow horizontally. The rhizome also retains the ability to allow new shoots ...
