Read this before the sheet
This plant, or one that resembles it, is dangerous. Identifying is not authorising: no app has the authority to tell you that you may eat or touch a plant.
Emergency
The white trumpet that opens at dusk on waste ground, followed by a spiny capsule. Everything about it is toxic, and serious poisonings in Portugal almost always come from recreational use.

Also known asjimsonweed, devil's snare
How to tell it
A white trumpet flower 6 to 10 cm long, with a sickly smell. A walnut-sized green fruit covered in stiff spines, splitting into four. Large leaves with irregular margins and an unpleasant smell.
What it is confused with
No dangerous lookalikes known in the Iberian Peninsula.
What it is for
None
The tropane alkaloids it contains cause delirium, tachycardia and death, and the concentration varies so much between plants that there is no predictable dose. That is why this sheet exists.
Where it occurs
Each square is an area with recorded observations of this plant. The lighter background is the set of areas where any of the entries has been observed, and serves as a reference. Note what this is not: it is not where the plant lives, it is where people record it, so trails and towns always look fuller than the mountains. Data from GBIF.
