Gloriosa superba

Gloriosa superba is a species of flowering plant in the family Colchicaceae. Common names include flame lily, climbing lily, creeping lily, glory lily, gloriosa lily, tiger claw, and fire lily.

This herbaceous perennial grows from a fleshy rhizome. It is scandent, climbing using modified leaf-tip tendrils, the stem reaching 4 m (13 ft) long. The leaves are mainly alternately arranged, but they may be opposite, as well. They are somewhat lance-shaped and tipped with tendrils, and they are up 13 to 20 cm (5.1 to 7.9 in) long. The showy flower has six tepals each up to 5 to 7.6 cm (2.0 to 3.0 in) long. They are generally bright red to orange at maturity, sometimes with yellowish bases. The margins may be quite wavy. The six stamens also are long, up to 4 cm (1.6 in), and each bears a large anther at the tip that drops large amounts of yellow pollen.

The style may be more than 6 cm (2.4 in) long. One flower may weigh over 2.5 g (0.09 oz). The fruit is a fleshy capsule up to 6 to 12 cm (2.4 to 4.7 in) long containing red seeds. Cultivars of this popular garden plant may vary from these wild-type characteristics; the cultivar 'Lutea' has all-yellow tepals, 'Citrina' is yellow with red markings, and 'Nana' is a dwarf. Whitish forms are also known.

Gloriosa superba is native to much of Africa, except North Africa. It is native to much of tropical Asia, including the Indian subcontinent and mainland and maritime Southeast Asia. It is also native to south-central China.

The species has been introduced to eastern Australia (New South Wales and Queensland), Alabama in the United States, Suriname, parts of the Caribbean, and various Pacific Islands.

The plant likely is pollinated by butterflies and sunbirds. It grows in many types of habitat, including tropical jungles, forests, thickets, woodlands, grasslands, and sand dunes. It can grow in nutrient-poor soils.^{[citation needed]} It can be found at as high as 2,500 m (8,200 ft) in elevation.

This plant is poisonous, and toxic enough to cause human and animal fatalities if ingested. It has been used to commit murder, to achieve suicide, and to kill animals. Every part of the plant is poisonous, especially the tuberous rhizomes. As with other members of the Colchicaceae, this plant contains high levels of colchicine, a toxic alkaloid. It also contains the alkaloid gloriocine. Within a few hours of the ingestion of a toxic amount of plant material, a victim may experience nausea, vomiting, numbness, tingling around the mouth, burning in the throat, abdominal pain, and bloody diarrhea, which leads to dehydration.^{[citation needed]} As the toxic syndrome progresses, rhabdomyolysis, ileus, respiratory depression, hypotension, coagulopathy, haematuria, altered mental status, seizures, coma, and ascending polyneuropathy may occur.^{[citation needed]} Longer-term effects include peeling of the skin and prolonged vaginal bleeding in women. Colchicine is known to cause alopecia. One case report described a patient who accidentally ate the tubers and then experienced hair loss over her entire body, including complete baldness. Poisonings can occur when the tubers are mistaken for sweet potatoes or yams and eaten. The plant can be dangerous for cats, dogs, horses, and livestock, as well.

The alkaloid-rich plant has long been used as a traditional medicine in many cultures. It has been used in the treatment of gout, infertility, open wounds, snakebite, ulcers, arthritis, cholera, colic, kidney problems, typhus, itching, leprosy, bruises, sprains, hemorrhoids, cancer, impotence, nocturnal emission,^{[citation needed]} smallpox, sexually transmitted diseases, and many types of internal parasites. It is an anthelmintic.^{[citation needed]} It has been used as a laxative and an alexiteric. The sap is used to treat acne and head lice.^{[citation needed]} In a pregnant woman, it may cause abortion. In parts of India, extracts of the rhizome are applied topically during childbirth to reduce labor pain.^{[citation needed]}
