River Crinum

Crinum macowanii is a deciduous bulbous plant of the Amaryllidaceae family, native to most of east, central and southern Africa and used in traditional medicine throughout southern Africa. It is called river crinum, Cape coast lily and sabie crinum in South Africa, common vlei-lily in Mozambique and pyjama lily in Tanzania and Kenya. Its local names include intelezi in Xhosa, umduze in Zulu and gitoka in Swahili. The flowers are long, slender, bell-shaped and highly scented, white with dark pink stripes, and the bulbs measure 6 to 25 centimetres across. Wikipedia says infusions of the bulb are used in Zimbabwe for back pain, as an emetic, and to increase lactation, and that the Zulu and Xhosa use the plant for swelling, urinary tract disorders and itchy rashes. Its continued existence is threatened by unsustainable harvesting for its medicinal reputation.
