A rose by any other name...

While wandering round Ingoldsby Wood I came across a rather odd looking rose with rather bristly hips. Although most wild roses have beautiful flowers in shades of pink and white, they are best identified from characters of the hips. Like many plants, roses don't really respect species boundaries, and this proved to be a hybrid which goes by the name of Rosa x scabriuscula. One of its parents is the Harsh Downy-rose Rosa tomentosa, which has bristly hips and glandular hairs on the flower-stalk, but the fact that some of the sepals are reflexed shows that its other parent was a Dog-rose Rosa canina. Real rose experts can even tell which species was the pollen parent and which was the seed parent - I can't!
