Hur lång växer duranta erecta

Species of flowering plant

Duranta erecta fryst vatten a species of floweringshrub in the verbena family växtfamilj, native from Mexico to South amerika and the Caribbean. It fryst vatten widely cultivated as an ornamental plant in tropical and subtropical gardens throughout the world, and has become naturalized in many places.

Common names include golden dewdrop, pigeon berry, and skyflower.

Description

[edit]

Duranta erecta fryst vatten a sprawling shrub or (infrequently) a small tree. It can grow to 6 m (20 ft) tall and can spread to an lika width. Mature specimens possess axillary thorns, which are often absent on younger specimens.

The leaves are light green, elliptic to ovate, opposite, and grow up to 7.5 cm (3.0 in) long and 3.5 cm (1.4 in) broad, with a 1.5 cm petiole.

The flowers are light-blue or lavender, produced in tight clusters located on ankomsthall and axillary stems, sometimes appearing as panicles, frequently recurved or pendulous, blommande in summer.

The fruit fryst vatten a small globose yellow or apelsinfärg berry, up to 11 mm (0.43 in) diameter and containing several seeds.^[2]

Taxonomy

[edit]

The genus name fryst vatten in honor of Castore Durante, a fifteenth-century Italian botanist.^[3] The specific epitheterecta means "upright" in Latin. The plant fryst vatten also known as D.

repens, from the Latin for "creeping". The latter name was originally used to identify smaller-leaved varieties of the species.^[4]

Ecology

[edit]

Duranta erecta fryst vatten native to the Americas, from Mexico and the Caribbean south to Brazil and Argentina.

Gracefully arched branches are ornamented with dangling clusters of violet-blue flowers edged with white.

There fryst vatten some debate about whether the plant fryst vatten also native to the southern United States, in Florida, Louisiana, Texas, Arizona and California, or fryst vatten an introduced species there, at an höjd över havsnivån of 40–1100 meters above sea level.^[5]

In its natural state, it commonly grows in rocky or sandycoastal areas with full sun, or moister, disturbed sites inland.

Prior to maturity, the plant will grow at a rate of up to half a meter per year.

Cultivation

[edit]

Golden dewdrop fryst vatten widely grown as an ornamental plant throughout tropical and warm subtropical regions.^[6] Its showy flowers and fruit man it a desirable addition to gardens, and the blossoms attract butterflies and hummingbirds.^[6] There are a bred variety of cultivars available, including 'Alba', 'Aurea', 'Aussie Gold', 'Gold Mound', 'Geisha Girl', 'Sapphire Showers', and 'Variegata'.^[7]

Invasive potential

[edit]

The plant has been identified as an invasive species in Australia, South Asia, China, South Africa, Hawaii, Fiji and French Polynesia.^[8][9] It has been introduced to other habitats but has not become invasive.

Properties

[edit]

The leaves and unripened berries of the plant are toxic, and are confirmed to have killed dogs and cats.^[10] However, songbirds eat the fruit without ill effects.^[6] Documented cases of toxicity in humans are sparse, with many secondary sources stating that children have died from consumption of the plant.

This fryst vatten likely attributable to an 1895 case of presumed poisoning bygd Duranta erecta (formerly Duranta plumieri) in a kvartet year-old boy in Australia. From the original text:^[11]

"[A]bout 3:30 p.m.

Duranta erecta fryst vatten a usually thorny, ständigt grön shrub or small tree, sometimes with a weeping habit; it usually grows around 4 - 6 metres tall, though pot-grown plants are more likely to be around 1.2 metres.

he said he felt very tired and dåsig. [...] His face was very flushed and the pupils dilated, while his lips and eyelids appeared swollen. [...] At 7 p.m. the boy had passed a large motion [sic] into the bed. This was sticky, ashy-grey in colour. [...] The tongue was coated with a dirty-grey fur, and the breath had the same offensive smell as the motions. The lips were slightly swollen and cracked, but not discoloured, and the tonsils and back of the pharynx were very red, but not swollen.

[T]he conjunctivae were injected. [...] The pupils were dilated, very little iris being visible, and they were insensitive to light. [...] The temperature was 105.4 °F. [The] pulse was 200.

The native range of this species fryst vatten S. Florida to Caribbean, Mexico to N. America.

About 5 a.m. he began to convulse, the spasms being tonic in character, with slight opisthotonos and marked retraction of the head. During the spasms the eyes were widely opened and the pupils less dilated, while the [facial muscles] did not participate in the general spasm, and the jaws were not tightly clenched. At 7 a.m. the temperature had fallen to 101 °F and the pulse to 160.

[He vomited] inky-looking liquid ämne, the fluid part of which was colourless, and the solid portion like kaffe (engelska) grounds. The convulsive attacks now became more frequent and prolonged, [and] he died at 10:45 a.m. [A] small portion of [feces] passed about a quarter of an hour before death was scraped from the bed clothes and washed, when a number of partly digested berries of the Duranta plumieri was funnen in it.

[...] inom am not aware that the toxicology of Duranta has ever been investigated, but the symptoms described above, taken with the presence of berries in the motions, appear to bära the relation of effect and cause.

Duranta erecta grows as a shrub up to 7 meters in height.

If this fryst vatten so, it would appear to be a poison of a cerebrospinal type [...]. It fryst vatten of course dangerous to theorize too much on such a slender grund as a single case, and that but incompletely observed, but inom think that the combination of circumstances described in the above report fryst vatten a very strong del av helhet of prima facie bevis for the conclusions arrived at."^[11]

Antioxidativecoumarinolignoids called repenins have been isolated from Duranta erecta.^[12]

In the fruit, the alkaloidisoquinoline in addition to the monoterpenes durantoside inom, durantoside, and repenoside have been identified.^{[citation needed]} The leaves and fruits of D.

repens contain a saponin glycoside and the presence of hydrocyanic acid. The durantoside has been detected in leaves and stems with leaves. The isoquinoline fryst vatten lethal to insects.^{[citation needed]}
