Chondrodendron tomentosum

Chondrodendron tomentosum is one of six accepted species [1] in the small genus Chondrodendron, belonging to the Moonseed family Menispermaceae. [2] It is a large tropical liana native to Central and South America. [3] It contains highly toxic alkaloids and is one of the sources of the arrow poison curare - specifically 'tube curare', the name of which is derived from the name of the medicinally valuable alkaloid tubocurarine. [4]

Derivation of scientific name

The generic name is a compound of Greek χόνδρος ( chondros ) 'cartilage' / 'lump' / 'grain' and δένδρον ( dendron ) 'tree' - hence 'lumpy / gristly tree', while the specific name consists of the Latin adjectival form tomentosum 'covered in matted hairs'. The binomial in its entirety thus conveys the image of a rather large coarse plant. [5]

Description

Chondrodendron tomentosum is a woody climbing plant with stems that can reach 10 cm in thickness at the base and which can climb up to 30 metres into the rainforest canopy. The large, glossy, cordate leaves are densely clothed beneath with a silky white pubescence, from which it gets its common name 'Velvet Leaf'. [6]

<i>Menispermum</i> Genus of flowering plants

Menispermum (moonseed) is a small genus of deciduous climbing woody vines in the moonseed family (Menispermaceae). Plants in this genus have small dioecious flowers, and clusters of small grape-like drupes. The name, moonseed, comes from the shape of the seed, which resembles a crescent moon. The word Menispermum is derived from the Greek words μήν (mēn), meaning (crescent) moon, and σπέρμα (sperma) meaning seed. The common name moonseed is also applied to some other species in the related genus Cocculus.

<i>Monstera deliciosa</i> Species of plant

Monstera deliciosa, the Swiss cheese plant or split-leaf philodendron is a species of flowering plant native to tropical forests of southern Mexico, south to Panama. It has been introduced to many tropical areas, and has become a mildly invasive species in Hawaii, Seychelles, Ascension Island and the Society Islands. It is very widely grown in temperate zones as a houseplant.

<i>Argyreia nervosa</i> Species of plant

Argyreia nervosa is a perennial climbing vine native to the Indian subcontinent and introduced to numerous areas worldwide, including Hawaii, Africa, and the Caribbean. Though it can be invasive, it is often prized for its aesthetic and medicinal value. Common names include Hawaiian baby woodrose, adhoguda अधोगुडा or vidhara विधारा (Sanskrit), elephant creeper and woolly morning glory. Its seeds are known for their powerful entheogenic properties, greater or similar to those of Ipomoea species, with users reporting significant psychedelic and spiritual experiences. The two botanical varieties are A. n. var. nervosa described here, and A. n. var. speciosa, which are used in Ayurvedic medicine for their medicinal value.

<i>Strychnos</i> Genus of flowering plants in the family Loganiaceae

Strychnos is a genus of flowering plants, belonging to the family Loganiaceae. The genus includes about 100 accepted species of trees and lianas, and more than 200 that are as yet unresolved. The genus is widely distributed around the world's tropics and is noted for the presence of poisonous indole alkaloids in the roots, stems and leaves of various species. Among these alkaloids are the well-known and virulent poisons strychnine and curare.

<span class="mw-page-title-main">Curare</span> Group of chemical substances used as poison

Curare is a common name for various alkaloid arrow poisons originating from plant extracts. Used as a paralyzing agent by indigenous peoples in Central and South America for hunting and for therapeutic purposes, curare only becomes active when it contaminates a wound. These poisons cause weakness of the skeletal muscles and, when administered in a sufficient dose, eventual death by asphyxiation due to paralysis of the diaphragm. Curare is prepared by boiling the bark of one of the dozens of plant sources, leaving a dark, heavy paste that can be applied to arrow or dart heads. In medicine, curare has been used as a treatment for tetanus and strychnine poisoning and as a paralyzing agent for surgical procedures.

<span class="mw-page-title-main">Menispermaceae</span> Family of flowering plants

Menispermaceae is a family of flowering plants. The alkaloid tubocurarine, a neuromuscular blocker and the active ingredient in the 'tube curare' form of the dart poison curare, is derived from the South American liana Chondrodendron tomentosum. Several other South American genera belonging to the family have been used to prepare the 'pot' and 'calabash' forms of curare. The family contains 68 genera with some 440 species, which are distributed throughout low-lying tropical areas with some species present in temperate and arid regions.

Tubocurarine is a toxic benzylisoquinoline alkaloid historically known for its use as an arrow poison. In the mid-1900s, it was used in conjunction with an anesthetic to provide skeletal muscle relaxation during surgery or mechanical ventilation. Safer alternatives, such as cisatracurium and rocuronium, have largely replaced it as an adjunct for clinical anesthesia and it is now rarely used.

<i>Catharanthus roseus</i> Species of flowering plant in the family Apocynaceae

Catharanthus roseus, commonly known as bright eyes, Cape periwinkle, graveyard plant, Madagascar periwinkle, old maid, pink periwinkle, rose periwinkle, is a perennial species of flowering plant in the family Apocynaceae. It is native and endemic to Madagascar, but grown elsewhere as an ornamental and medicinal plant. It is a source of the drugs vincristine and vinblastine, used to treat cancer.

The fruits, which are globular and largely enclosed by the accrescent calyces, can reach a kilogram in weight and have a taste described as apple-like or melon-like.

The flora of China consists of a diverse range of plant species including over 39,000 vascular plants, 27,000 species of fungi and 3000 species of bryophytes. More than 30,000 plant species are native to China, representing nearly one-eighth of the world's total plant species, including thousands found nowhere else on Earth. China's land, extending over 9.6 million km, contains a variety of ecosystems and climates for plants to grow in. Some of the main climates include shores, tropical and subtropical forests, deserts, elevated plateaus and mountains. The events of the continental drift and early Paleozoic Caledonian movement also play a part in creating climatic and geographical diversity resulting in high levels of endemic vascular flora. These landscapes provide different ecosystems and climates for plants to grow in, creating a wide variety of different flora spanning over not just China, but different parts of the world.
