New succulents and free spiders

I went off to a local flea market today and realised that I'd had a brain fart about the dates. It falls on the first and last Sunday of every month and today is the first, so I missed it last week. Sadly, I have never been much good at knowing what day of the week it is, much less the date. I got some new things from my favourite succulent seller. He couldn't remember what this is called, and suggested osteo... osteoporosis. I told him that Osteoporisis is a medical condition: does anyone have a clue what this plant is? * Update: it is Orostachys fimbriata or Dunce’s Cap *

I got these, and I do know what they are, clockwise from left: Aloe "Tuffy", Gasteria nigricans cultivar, Cotyledon, Aeonium and Haworthia limifolia

Then I found a stall selling old clay pots so I got a few of those and look who was hiding in the bottom, very well camouflaged:

I tried putting her in the tree but she jumped off and headed in a direction that was likely to get her squashed so I put her back in her pot and took her home with me. She's a nursery web spider, one of the medium-sized hunting spiders and they often do end up stuck inside buckets and plant pots because they fall in and they can't get out if the sides are too steep. I brought her home and put her pot sideways under a bush so that she can make her way out when she feels ready.
