Polygonatum / ˌ p ɒ l ɪ ˈ ɡ ɒ n ə t əm /, [2] also known as King Solomon's-seal or Solomon's seal, is a genus of flowering plants. In the APG III classification system , it is placed in the family Asparagaceae , subfamily Nolinoideae (formerly the family Ruscaceae). [ 3 ]
Polygonum is a genus of about 130 species of flowering plants in the buckwheat and knotweed family Polygonaceae.Common names include knotweed and knotgrass (though the common names may refer more broadly to plants from Polygonaceae).
Persicaria amphibia (syn. Polygonum amphibium) is a species of flowering plant in the knotweed family known by several common names, including longroot smartweed, water knotweed, water smartweed, and amphibious bistort.
Vegetative reproduction (also known as vegetative propagation, vegetative multiplication or cloning) is a form of asexual reproduction occurring in plants in which a new plant grows from a fragment or cutting of the parent plant or specialized reproductive structures, which are sometimes called vegetative propagules.
Plant propagation is the process by which new plants grow from various sources, including seeds, cuttings, and other plant parts. Plant propagation can refer to both man-made and natural processes. Plant propagation can refer to both man-made and natural processes.
Polygonatum biflorum (smooth Solomon's-seal, great Solomon's-seal, Solomon's seal) is an herbaceous flowering plant native to eastern and central North America. [2] The plant is said to possess scars on the rhizome that resemble the ancient Hebrew seal of King Solomon. [3] It is often confused with Solomon's plume, which has upright flowers.
For a certain water depth, surface gravity waves – i.e. waves occurring at the air–water interface and gravity as the only force restoring it to flatness – propagate faster with increasing wavelength. On the other hand, for a given (fixed) wavelength, gravity waves in deeper water have a larger phase speed than in shallower water. [1]
Propagation of a continuous flow can be thought of as the same as that of the tail (or body) of a very long finite volume. Gravity flows are described as consisting of two parts, a head and a tail. The head, which is the leading edge of the gravity current, is a region in which relatively large volumes of ambient fluid are displaced.
