Giuseppe Giacinto Moris
Giuseppe Giacinto Moris (25 April 1796, Orbassano – 18 April 1869, Turin) was an Italian botanist known for investigations of flora native to Sardinia. He studied medicine in Turin, from where he graduated while still in his teens. From 1822 to 1829, he worked as a professor at the University of Cagliari, afterwards returning to Turin as a professor at the University of Turin, university. Here, he was director of its botanical garden from 1831 until 1869. He was the binomial authority of the genus ''Ridolfia segetum, Ridolfia'' (family Apiaceae) as well as of numerous plant species. In 1832, Jaques Étienne Gay named the genus ''Morisia'' (family Brassicaceae) in his honor.

Apioideae
This is a list of genera belonging to the family Apiaceae. It contains all the genera listed by Plants of the World Online (PoWO) . A few extra genus names are included that PoWO regards as synonyms. Unless otherwise indicated, the placement of genera into sub-taxa is based on the taxonomy used by the Germplasm Resources Information Network (GRIN). "Not assigned" means either that the genus is unplaced in GRIN or that it is not listed by GRIN. Not assigned to a subfamily In a 2021 molecular phylogenetic study, the ''Platysace'' clade and the genera ''Klotzschia'' and ''Hermas'' fell outside the four subfamilies. It has been suggested that they could be placed in subfamilies of their own. *'' Hermas'' *'' Klotzschia'' *'' Platysace'' ;Others *'' Actinanthus'' *'' Adenosciadium'' *'' Agasyllis'' *'' Angoseseli'' *'' Apodicarpum'' *'' Asciadium'' *'' Austropeucedanum'' *'' Brachyscias'' *'' Caropodium'' *'' Caropsis'' *''Chaetosciadium'' *'' Dactylaea'' *'' Dethawi ...

Glabrousness
Glabrousness () is the technical term for a lack of hair, down, setae, trichomes, or other such covering. A glabrous surface may be a natural characteristic of all or part of a plant or animal, or be due to loss because of a physical condition, such as alopecia universalis in humans, which causes hair to fall out or not regrow. In botany Glabrousness or otherwise, of leaves, stems, and fruit is a feature commonly mentioned in plant keys; in botany and mycology, a ''glabrous'' morphological feature is one that is smooth and may be glossy. It has no bristles or hair-like structures such as trichomes. In anything like the zoological sense, no plants or fungi have hair or wool, although some structures may resemble such materials. The term "glabrous" strictly applies only to features that lack trichomes at all times. When an organ bears trichomes at first, but loses them with age, the term used is ''glabrescent''. In the model plant ''Arabidopsis thaliana'', trichome formation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Essential Oil
An essential oil is a concentrated hydrophobic liquid containing volatile (easily evaporated at normal temperatures) chemical compounds from plants. Essential oils are also known as volatile oils, ethereal oils, aetheroleum, or simply as the oil of the plant from which they were extracted, such as oil of clove. An essential oil is essential in the sense that it contains the essence of the plant's fragrance—the characteristic fragrance of the plant from which it is derived. The term "essential" used here does ''not'' mean required or usable by the human body, as with the terms essential amino acid or essential fatty acid, which are so called because they are nutritionally required by a living organism. Essential oils are generally extracted by distillation, often by using steam. Other processes include expression, solvent extraction, '' sfumatura'', absolute oil extraction, resin tapping, wax embedding, and cold pressing. They are used in perfumes, cosmetics, soaps, ...

α-phellandrene
Phellandrenes are organic compounds with the formula . They have a similar molecular structure and similar chemical properties. α-Phellandrene and β-phellandrene are cyclic monoterpenes and are double-bond isomers. In α-phellandrene, both double bonds are endocyclic, and in β-phellandrene, one of them is exocyclic. Both are insoluble in water, but miscible with organic solvents. Etymology and occurrence α-Phellandrene was named after ''Eucalyptus phellandra'', now called ''Eucalyptus radiata'', from which it can be isolated. It is also a constituent of the essential oil of ''Eucalyptus dives''. β-Phellandrene has been isolated from the oil of water fennel and Canada balsam oil. The main source of β-phellandrene is terpentine. β-pinene is a source of β-phellandrene. Reactions and uses α-Phellandrene undergoes hydrochlorination to give phellandrene hydrochloride (a cyclohexenyl chloride). Base hydrolysis of this hydrochloride gives piperitol. The phellandrene ...

Terpinene
The terpinenes are a group of isomeric hydrocarbons that are classified as monoterpenes. They each have the same molecular formula and carbon framework, but they differ in the position of carbon-carbon double bonds. α-Terpinene has been isolated from cardamom and marjoram oils, and from other natural sources. β-Terpinene has no known natural source but has been prepared from sabinene. γ-Terpinene and δ-terpinene (also known as terpinolene) have been isolated from a variety of plant sources. They are all colorless liquids with a turpentine-like odor. Production and uses α-Terpinene is produced industrially by acid-catalyzed rearrangement of α- pinene. It has perfume and flavoring properties but is mainly used to confer pleasant odor to industrial fluids. Hydrogenation gives the saturated derivative ''p''-menthane. Biosynthesis of α-terpinene The biosynthesis of α-terpinene and other terpenoids starts with the isomerization of geranyl pyrophosphate to linalyl py ...

Dillapiol
Dillapiole is an organic chemical compound and essential oil commonly extracted from dill weed, though it can be found in a variety of other plants such as fennel root. This compound is closely related to apiole, having a methoxy group positioned differently on the benzene ring. Dillapiole works synergically with certain insecticides like pyrethrins similarly to piperonyl butoxide, which likely results from inhibition of the MFO enzyme of insects. No carcinogenicity was detected with parsley apiol or dill apiol in mice. See also * Pseudodillapiole References See also * Apiole * Phenylpropene Phenylpropenes broadly are compounds containing a phenyl ring bonded to propene, more specifically those with an allyl group bonded to a benzene ring, having the parent structure of allylbenzene.

Edible Apiaceae
An edible item is any item that is safe for humans to eat. "Edible" is differentiated from "palatability, eatable" because it does not indicate how an item tastes, only whether it is fit to be eaten. Nonpoisonous items found in nature – such as some edible mushroom, mushrooms, insects as food, insects, edible seaweed, seaweed, and so forth – are referred to as edible. Processed items that normally are not ingested but are specially manufactured to be so, like edible underwear or edible packaging, are also labeled as edible. Edible items in nature Humans eat thousands of plant species; there may be as many as 75,000 edible species of angiosperms, of which perhaps 7,000 are often eaten. Edible plants found in nature include List of edible flowers, flowers, List of edible seeds, seeds, berry, berries, edible seaweed, seaweed, and List of edible cacti, cacti. Being able to identify the versions of these plants that are safe to eat is an important survival skills, survival skill. ...

Monotypic Apioideae Genera
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. Theoretical implications Monotypic taxa present several important theoretical challenges in biological classification. One key issue is known as "Gregg's Paradox": if a single species is the only member of multiple hierarchical levels (for example, being the only species in its genus, which is the only genus in its family), then each level needs a distinct definition to maintain logical structure. Otherwise, the different taxonomic ranks become effectively identical, which creates problems for organizing biological diversity in a hierarchical system. ...
