Species

Incarvillea is a genus of about 16 species [1] [2] of flowering plants in the family Bignoniaceae, native to central and eastern Asia, with most of the species growing at high altitudes in the Himalaya and Tibet. The most familiar species is Incarvillea delavayi , a garden plant commonly known as hardy gloxinia [note 1] or Chinese trumpet flower. Unlike most other members of Bignoniaceae, which are mainly tropical woody plants, species of Incarvillea are herbaceous perennial plants from temperate regions. [2]

Contents

Genetic analysis supports the division of the genus into five clades: the subgenus Niedzwedzkia, the subgenus Amphicome, the subgenus Incarvillea, the subgenus Pteroscleris, and the species I. olgae, which does not fit into a subgenus. It may be given a subgenus of its own in a future study. [2]

Incarvillea is named after the French Jesuit missionary and botanist Pierre Nicholas Le Chéron d'Incarville. [3]

Species include:

Chemistry

Incarvillea sinensis contains the alkaloid incarvillateine. [4]

Notes

  1. even though Incarvillea is not closely related to Gloxinia and Sinningia ("florist Gloxinia"), which are Gesneriads.

Magnolia is a large genus of about 210 flowering plant species in the subfamily Magnolioideae of the family Magnoliaceae. It is named after French botanist Pierre Magnol.

<i>Fritillaria</i> Genus of flowering plants in family Liliaceae

Fritillaria (fritillaries) is a genus of spring flowering herbaceous bulbous perennial plants in the lily family (Liliaceae). The type species, Fritillaria meleagris, was first described in Europe in 1571, while other species from the Middle East and Asia were also introduced to Europe at that time. The genus has about 130–140 species divided among eight subgenera. The flowers are usually solitary, nodding and bell-shaped with bulbs that have fleshy scales, resembling those of lilies. They are known for their large genome size and genetically are very closely related to lilies. They are native to the temperate regions of the Northern hemisphere, from the Mediterranean and North Africa through Eurasia and southwest Asia to western North America. Many are endangered due to enthusiastic picking.

Bignoniaceae Family of flowering plants

Bignoniaceae is a family of flowering plants in the order Lamiales commonly known as the bignonias. It is not known to which of the other families in the order it is most closely related.

<i>Ophiocordyceps sinensis</i> Species of fungus

Ophiocordyceps sinensis is known in English colloquially as caterpillar fungus, or by its more prominent names yartsa gunbu, or dōng chóng xià cǎo or Yarsa-gumba or Yarcha-gumba, or Keeda Jadi, or ရှီးပတီး. It is an entomopathogenic fungus in the family Ophiocordycipitaceae. It is mainly found in the meadows above 3,500 meters on Tibetan Plateau in Southwest China and Himalayan regions of Bhutan and Nepal. It parasitizes larvae of ghost moths and produces a fruiting body which used to be valued as a herbal remedy and in traditional Chinese medicine. Caterpillar fungus contains the compound Cordycepin, an adenosine derivative. However, the fruiting bodies harvested in nature usually contain high amounts of arsenic and other heavy metals so they are potentially toxic and sales have been strictly regulated by the CFDA since 2016.

Camellia sinensis is a species of evergreen shrubs or small trees in the flowering plant family Theaceae. Its leaves and leaf buds are used to produce tea. Common names include "tea plant", "tea shrub", and "tea tree".

<i>Symphoricarpos</i> Genus of flowering plants in the honeysuckle family Caprifoliaceae

Symphoricarpos, commonly known as the snowberry, waxberry, or ghostberry, is a small genus of about 15 species of deciduous shrubs in the honeysuckle family, Caprifoliaceae. With the exception of the Chinese coralberry, S. sinensis, which is indigenous to western China, all species are native to North and Central America. The name of the genus is derived from the Ancient Greek words συμφορεῖν (sumphoreîn), meaning "to bear together", and καρπός (karpós), meaning "fruit". It refers to the closely packed clusters of berries the species produces.

Euphorbiaceae Family of Eudicot flowering plants

The Euphorbiaceae, the spurge family, are a large family of flowering plants. In common English, they are sometimes called euphorbias, which is also the name of a genus in the family. Most spurges, such as Euphorbia paralias, are herbs, but some, especially in the tropics, are shrubs or trees, such as Hevea brasiliensis. Some, such as Euphorbia canariensis, are succulent and resemble cacti because of convergent evolution. This family has a cosmopolitan distribution, with greatest diversity in the tropics. However, the Euphorbiaceae also have many species in nontropical areas of all continents except Antarctica.

The endocannabinoid transporters (eCBTs) are transport proteins for the endocannabinoids. Most neurotransmitters are water-soluble and require transmembrane proteins to transport them across the cell membrane. The endocannabinoids on the other hand, are non-charged lipids that readily cross lipid membranes. However, since the endocannabinoids are water immiscible, protein transporters have been described that act as carriers to solubilize and transport the endocannabinoids through the aqueous cytoplasm. These include the heat shock proteins (Hsp70s) and fatty acid-binding proteins for anandamide (FABPs). FABPs such as FABP1, FABP3, FABP5, and FABP7 have been shown to bind endocannabinoids. FABP inhibitors attenuate the breakdown of anandamide by the enzyme fatty acid amide hydrolase (FAAH) in cell culture. One of these inhibitors (SB-FI-26), isolated from a virtual library of a million compounds, belongs to a class of compounds that act as an anti-nociceptive agent with mild anti-inflammatory activity in mice. These truxillic acids and their derivatives have been known to have anti-inflammatory and anti-nociceptive effects in mice and are active components of a Chinese herbal medicine used to treat rheumatism and pain in human. The blockade of anandamide transport may, at least in part, be the mechanism through which these compounds exert their anti-nociceptive effects.

Incarvillea semiretschenskia is a rare perennial flower endemic to dry, rocky hillsides in Kazakhstan, placed on the IUCN Red List in 1997. It was first described as Niedzwedzkia semiretschenskia, the only species in the genus Niedzwedzkia. It has also been placed as the only species in Incarvillea subgenus Niedzwedzkia.

<i>Allium</i> Genus of flowering plants in the family Amaryllidaceae

The generic name Allium is the Latin word for garlic, and the type species for the genus is Allium sativum which means "cultivated garlic".

Solanaceae Family of flowering plants that includes tomatoes, potatoes and tobacco

The Solanaceae, or nightshades, are a family of flowering plants that ranges from annual and perennial herbs to vines, lianas, epiphytes, shrubs, and trees, and includes a number of agricultural crops, medicinal plants, spices, weeds, and ornamentals. Many members of the family contain potent alkaloids, and some are highly toxic, but many—including tomatoes, potatoes, eggplant, bell and chili peppers—are used as food. The family belongs to the order Solanales, in the asterid group and class Magnoliopsida (dicotyledons). The Solanaceae consists of about 98 genera and some 2,700 species, with a great diversity of habitats, morphology and ecology.
