Indian-apple

Datura innoxia, known as Indian-apple, pricklyburr, or downy thorn-apple, is a coarse, sprawling annual or short-lived perennial herb in the Solanaceae family native to the south-western United States, Mexico, Central America, and South America. The plant grows fifty centimetres to two metres tall with branching, somewhat downy, greyish-green stems. The alternate leaves are broadly ovate, soft and velvety with shallow, irregularly toothed margins and a heavy, narcotic smell when crushed. Large solitary trumpet-shaped flowers, fifteen to twenty centimetres long, open in the evening; the corolla is white, sometimes flushed with lavender, with ten slender pointed lobes. The fruits are nodding spherical capsules densely covered with stout spines, splitting irregularly to release numerous flattened pale brown seeds. All parts of the plant contain potent tropane alkaloids (hyoscyamine, scopolamine, atropine) and are highly toxic.
