Confidence: It's likely to be this, but I can't be certain.
Notes: Broomrapes are parasitic on other plants. This is growing in grassland where Common Broomrape is likelier to occur with the presence of clover and other herbaceous plants. I think I can see a clover plant to the middle left of the image. The height and colour seem right and Common Broomrape occurs in the area of this sighting.
