I must admit, my knowledge of mainstream scents is not all that great - I'm a bit of a perfume newbie, having been on Basenotes less than a year. I'm still learning!
Sample A then...
Sharp green opening - galbanum? Something a little animalic too, and maybe iris? It's quite astringent on my skin to begin with.
After a while it softens to a lovely jasmine. There are other flowers here, but my nose isn't doing a great job of distinguishing them. Maybe a hint of rose?
I'm going to have a stab at No.19.
