Magnolia in the context of "Eudicotyledon"

A plant cutting is a piece of a plant that is used in horticulture for vegetative (asexual) propagation. A piece of the stem or root of the source plant is placed in a suitable medium such as moist soil. If the conditions are suitable, the plant piece will begin to grow as a new plant independent of the parent, a process known as striking. A stem cutting produces new roots, and a root cutting produces new stems. Some plants can be grown from leaf pieces, called leaf cuttings, which produce both stems and roots. The scions used in grafting are also called cuttings.

Propagating plants from cuttings is an ancient form of cloning. There are several advantages of cuttings, mainly that the produced offspring are practically clones of their parent plants. If a plant has favorable traits, it can continue to pass down its advantageous genetic information to its offspring. This is especially economically advantageous as it allows commercial growers to clone a certain plant to ensure consistency throughout their crops.

The eudicots or eudicotyledons are flowering plants that have two seed leaves (cotyledons) upon germination. The term derives from dicotyledon (etymologically, eu = true; di = two; cotyledon = seed leaf). Historically, authors have used the terms tricolpates or non-magnoliid dicots. The current botanical terms were introduced in 1991, by evolutionary botanist James A. Doyle and paleobotanist Carol L. Hotton, to emphasize the later evolutionary divergence of tricolpate dicots from earlier, less specialized, dicots.

Scores of familiar plants are eudicots, including many commonly cultivated and edible plants, numerous trees, tropicals and ornamentals. Among the most well-known eudicot genera are those of the sunflower (Helianthus), dandelion (Taraxacum), forget-me-not (Myosotis), cabbage (Brassica), apple (Malus), buttercup (Ranunculus), maple (Acer) and macadamia (Macadamia). Most leafy, mid-latitude trees are also classified as eudicots, with notable exceptions being the magnolias and American tulip tree (Liriodendron)—which belong to the magnoliids—and Ginkgo biloba, which is not an angiosperm.

A tepal is one of the outer parts of a flower (collectively the perianth). The term is used when these parts cannot easily be classified as either sepals or petals. This may be because the parts of the perianth are undifferentiated (i.e. of very similar appearance), as in Magnolia, or because, although it is possible to distinguish an outer whorl of sepals from an inner whorl of petals, the sepals and petals have similar appearance (as in Lilium). The term was proposed by Augustin Pyramus de Candolle in 1827 and was constructed by analogy with the terms "petal" and "sepal". (De Candolle used the term perigonium or perigone for the tepals collectively; the term is since used as a synonym for perianth.)

Magnolia × wieseneri is a hybrid plant in the genus Magnolia and family Magnoliaceae. A small tree or large shrub with white highly fragrant blooms, it is the progeny of Magnolia sieboldii and Magnolia obovata.

The San Francisco Botanical Garden at Strybing Arboretum (formerly Strybing Arboretum) is located in San Francisco's Golden Gate Park. Its 55 acres (22.3 ha) represents nearly 9,000 different kinds of plants from around the world, with particular focus on Magnolia species, high elevation palms, conifers, and cloud forest species from Central America, South America and Southeast Asia.

San Francisco's County Fair Building is located near the main entrance to the Garden.

Magnoliids, Magnoliidae or Magnolianae are a clade of flowering plants. With more than 10,000 species, including magnolias, nutmeg, bay laurel, cinnamon, avocado, black pepper, tulip tree and many others, it is the third-largest group of angiosperms after the eudicots and monocots. The group is characterized by trimerous flowers, pollen with one pore, and usually branching-veined leaves.

Some members of the subclass are among the earliest angiosperms and share anatomical similarities with gymnosperms like stamens that resemble the male cone scales of conifers and carpels found on the long flowering axis. According to molecular clock calculations, the lineage that led to magnoliids split from other plants about 135 million years ago or 160-165 million years ago.

The Magnoliaceae (/mæɡˌnoʊliˈeɪsii/) are a flowering plant family, the magnolia family, in the order Magnoliales. It consists of two genera: Magnolia and Liriodendron (tulip trees).

Unlike most angiosperms, whose flower parts are in whorls (rings), the Magnoliaceae have their stamens and pistils in spirals on a conical receptacle. This arrangement is found in some fossil plants and is believed to be a basal or early condition for angiosperms. The flowers also have parts not distinctly differentiated into sepals and petals, while angiosperms that evolved later tend to have distinctly differentiated sepals and petals. The poorly differentiated perianth parts that occupy both positions are known as tepals.

Honokiol is a lignan isolated from the bark, seed cones, and leaves of trees belonging to the genus Magnolia. It has been identified as one of the chemical compounds in some traditional Eastern herbal medicines along with magnolol, 4-O-methylhonokiol, and obovatol.

Honokiol, a compound with a spicy odor extracted from various Magnolia species worldwide, including those native to the Southeastern United States and Mexico, can readily cross the blood-brain and cerebrospinal fluid barriers, making it a highly bioavailable and potentially effective therapeutic agent. Honokiol is a small, hydrophobic neolignan biphenol structurally similar to propofol that can be purified efficiently from its isomer magnolol using advanced chromatography techniques such as magnolol acetonide protection followed by flash chromatography or high-capacity high-speed countercurrent chromatography.
