How to tell it
Lower leaves entire and oval, upper ones deeply cut into segments, giving the plant two different faces. Very small pale pink flowers in loose clusters, each with a short spur behind. A tender hollow stem.
What it is confused with
No dangerous lookalikes known in the Iberian Peninsula.
What it is for
No relevant use
It counts as an exercise: a plant whose lower and upper leaves look like different species teaches you not to identify anything from a single leaf.
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.
