https://en.wikipedia.org/wiki/Rose_hip
Rose hip can be of different species, and 'elongated form' and specific orange or red color arent a must.
Rose hips that I captured today for the chalenge are exactly like in this post . I saw the 'elongated' ones but not in this location where I live, more to the south. Both are rosehips, just different species.
But I agree with you - the photos were taken not recently, probably in the summer. I cant say I see a person put some efforts to execute the challenge task - go out, find something, and describe it...
