Datura inoxia

Datura innoxia, often spelled inoxia, (sometimes called by the common names pricklyburr, recurved thorn-apple, downy thorn-apple, Indian-apple, lovache, moonflower, nacazcul, toloatzin, tolguache or toloache) is a species in the family Solanaceae. It is more rarely called sacred datura, but this name in fact refers to the related Datura wrightii. It is native to S.W. United States, Central and South America, and introduced in Africa, Asia, Australia and Europe. The scientific name is often cited as D. innoxia. When English botanist Philip Miller first described the species in 1768, he misspelled the Latin word innoxia (inoffensive) when naming it D. inoxia. The name Datura meteloides was for some time erroneously applied to some members of the species, but that name has now been abandoned. Datura innoxia is an annual shrubby plant that typically reaches a height of 0.6 to 1.5 metres. Its stems and leaves are covered with short and soft grayish hairs, giving the whole plant a grayish appearance. It has elliptic smooth-edged leaves with pinnate venation. All parts of the plant emit a foul odor similar to rancid peanut butter when crushed or bruised, although most people find the fragrance of the flowers to be quite pleasant when they bloom at night. The flowers are white, trumpet-shaped, 12–19 cm (4.5–7.5 in) long. They first grow upright, and later incline downward. It flowers from early summer until late fall. The fruit is an egg-shaped spiny capsule, about 5 cm in diameter. It splits open when ripe, dispersing the seeds. Another means of dispersal is by the fruit spines getting caught in the fur of animals, who then carry the fruit far from the mother plant. The seeds have hibernation capabilities, and can last for years in the soil. The seeds, as well as the entirety of this plant, act as deliriants, but have a high probability of overdose. The currently-accepted botanical name for this plant is Datura innoxia, in spite of the fact that many references spell it Datura inoxia. According to Tropicos, a widely-accepted authority on botanical names, the inoxia form is due to an error originally made by 18th century taxonomist Philip Miller, and since corrected. Modern authorities state that the inoxia form literally means 'not noxious', which certainly does not seem to apply to the highly poisonous Datura. On the other hand, Miller said that the 'not noxious' form refers to the soft spines on the fruit, which are in contrast to the sharp spines on other Datura species. (Miller refers to the ... 'oval fruit, covered with long, soft, innocent spines' ...). All parts of Datura plants contain dangerous levels of poison and may be fatal if ingested by humans and other animals, including livestock and pets. In some places it is prohibited to buy, sell or cultivate Datura plants. When cultivated, the plant is usually grown from seed, but its perennial rhizomes can be kept from freezing and planted in the spring of the following year.
