Organism of the week #18 – Feeling rotten

It’s been ages since I did one of these, and today’s will not be terribly long or exciting, for the reason that is the very title of this post. Whilst bumbling around in the fridge looking for something bland and bowel-friendly, I chanced upon a lemon that had fallen into a oubliette in the bottom of the salad drawer. Perhaps it’s just the sickness talking, but I found it rather beautiful:
